Organization</title>
<para>
The content of this guide has been split into 7 distinct sections called "Chapters" as illustrated below for ease of searching and reading on behalf of the reader. The reader is expected to choose any one Microsoft Windows operating system from the list mentioned in Chapter 2, thus the other sections regarding Microsoft Windows operating systems could be skipped "without" any risk at all. After the reader has chosen which Microsoft operating system to install, he/she can proceed with the installation, then proceed with the FreeBSD/OpenBSD/NetBSD and Linux installations sequentially.</para>
<para>
Chapter 1: The first Chapter, About the operating systems covers a brief discussion on Windows operating system family (I chose to speak a few words on Microsoft Windows XP Professional), Linux, FreeBSD, OpenBSD and NetBSD operating systems. General information on each operating system, legal stuff etc. is discussed. For more official and exhaustive information, refer to the official web-sites of the products and projects listed there.</para>
<para>
Chapter 2: The second Chapter, Installing Microsoft Windows covers the installation of any one of Microsoft Windows operating system that the reader chooses to install on a new hard disk. The operating system that the reader chooses to install here is the one that would co-exist finally with the FreeBSD/OpenBSD/NetBSD and Red Hat Linux operating systems. Disk partitioning and labeling schemes under Windows is discussed in detail herein.</para>
<para>
Chapter 3: The third Chapter, Installing FreeBSD 5.1-RELEASE covers topics required for installing and configuring FreeBSD 5.1-RELEASE with the already existing Microsoft Windows operating system. If the reader chooses to install OpenBSD 3.2-RELEASE instead of FreeBSD 5.1-RELEASE, he/she may skip this chapter and proceed to the next chapter.</para>
<warning>
<para>WARNING: Since both FreeBSD and OpenBSD operating systems are POSIX compliant BSD-derivatives, both use the same BSD-style hard disk partitioning and labeling schemes, and both have the same set of commands when viewed from the user-level. Thus, partitioning and filesystems naming covered in FreeBSD section will not be repeated in the next chapter. If it so happens that you are a complete OpenBSD newbie or the term "OpenBSD" sounds like a Greek mythology character, it is best for you to go through all the information in this chapter and install and configure FreeBSD. The OpenBSD installation, though simple and neat, is a text-based installation procedure completely and assumes a sound knowledge of hardware, BSD-style hard disk slicing and labeling schemes. Messing up at any one stage, messes up the entire installation and may even render the Microsoft Windows operating system (installed initially) totally inaccessible. Experience has taught me to keep proper backup when doing such installations. Do not send problem reports later. You have been warned!</para>
</warning>
<para>
Chapter 4: The fourth Chapter, Installing OpenBSD 3.2-RELEASE covers topics required for installing and configuring OpenBSD 3.2-RELEASE with the already existing Microsoft Windows operating system. If the reader chooses to install FreeBSD 5.1-RELEASE instead of OpenBSD 3.2-RELEASE, he/she may skip this chapter and take a peek into the earlier chapter. Partitioning and essential booting process details etc. is discussed herein.</para>
<para>
Chapter 5: The fifth Chapter, Installing NetBSD 1.6.1 covers topics needed for installing and configuring NetBSD 1.6.1 with the already existing Microsoft Windows operating system. If the reader chooses to install FreeBSD 5.1-RELEASE or OpenBSD 3.2-RELEASE, he/she may skip this chapter and take a peek into the earlier chapters. Partitioning and essential booting process details etc. is discussed herein. </para>
<para>
Chapter 6: The sixth Chapter, Installing Red Hat Linux 8.0 (Psyche) covers the topics required for installing and configuring Red Hat Linux 8.0 distribution release with the already pre-existing Microsoft Windows operating system and FreeBSD 5.1-RELEASE/OpenBSD 3.2-RELEASE/NetBSD 1.6.1.</para>
<para>
Chapter 7: The seventh and the final Chapter, Mounting Filesystems contains a detailed discussion on topics required for mounting Linux filesystem (ext2fs) on FreeBSD systems and mounting UFS (or FFS) on Linux systems and other minute yet significant details. Readers interested in gathering working knowledge on Linux filesystems must browse through the contents of this Chapter.</para>

<chapter>
<title>About the operating systems</title>
<para>
A general overview of the operating systems that have been covered in
this guide has been provided here. Readers must note that these are my
personal views (and comments) and have nothing to do with the views of
the Linux/FreeBSD/OpenBSD/NetBSD or in general terms, the Open-Source
community.</para>
<section>
<title> Microsoft Windows</title>
<para> Microsoft Corp. has a long (yet fatally weak and buggy) list of operating systems, targets ranging from the mild and feeble home-user to the truly multi-tasking, multi-processing, multi-programming, fault-tolerant, hack-resilient real-time systems; from MS Windows 95 to the most recently launched Microsoft Windows Server 2003. The reader is free to choose any operating system according to his/her own personal taste and/or targeted environment. I personally do "not" consider Microsoft Windows 2000 family of operating systems (Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server and Windows 2000 DataCenter server) a very good choice for "corporate" environments. If the PASSME theme of Software engineering is considered, where PASSME = Performance, Availability, Scalability, Security, Maintainability and Extensibility features of any software under scrutiny; Microsoft Windows 2000 servers (and operating systems, in general) are rated much lower than UNIX SVR4, *BSDs, Sun Solaris, Linux and any of the other commercial variants of UNIX like IBM-AIX, HP-UX, Digital UNIX, Tru64 UNIX, SGI-Irix and so on.</para>

<title>Linux</title>
<para>Linux is the kernel or core of an operating system called
GNU/Linux system, where the GNU Project provides the software
and applications that runs on the Linux kernel. The Linux
kernel, originally written by Linus Benedict Torvalds, is a
UNIX-clone, which is POSIX compliant and was initially targeted
towards the Intel x86 architecture. As rightly mentioned in the
"Linux Information Sheet" by Michael K. Johnson at
http://www.tldp.org, "...Linux is a completely free
reimplementation of the POSIX specification, with SYSV and BSD
extensions (which means it looks like Unix, but does not come
from the same source code base), which is available in both
source code and binary form. Its copyright is owned by Linus
Torvalds ; and other contributors, and is freely redistributable
under the terms of the GNU General Public License (GPL). A copy
of the GPL is included with the Linux source; you can also get a
copy from ftp://prep.ai.mit.edu/pub/gnu/COPYING...". </para>
<para>
Readers must note the fact that though many Linux users worldwide refer to the GNU/Linux operating system simply as "Linux", it is more appropriate to refer to the operating system as a GNU/Linux system and when talking about the kernel in particular just to call it Linux. Moreover, a very popular misconception amongst new Linux users is: "Hey! Linux is UNIX!". No, absolutely "not". Once again, readers must note: The Linux kernel is a UNIX-clone, in other words a reimplementation of the UNIX-Kernel, but it is not UNIX itself. On the other hand, the BSDs, FreeBSD and OpenBSD for example, are not kernels merely. They are more closer to the real UNIX (AT&Ts Official Release UNIX SVR4). They represent an entire operating system with a whole set of applications, tools, user utilities, shells, games, documentation, developer utilities, system and user-level binaries and full source code for the operating systems.</para>

<title>*BSD's</title>
<section>
<title>FreeBSD</title>
<para>
FreeBSD which stands for the Free version of Berkeley Software Distribution operating system software (though all the BSDs out there are "open-source" or "free" in nature except BSD/OS) is technically speaking, the most powerful, professional quality and advanced UNIX-compatible operating system software on earth today. FreeBSD is originally based on 4.4BSD-Lite (with a minor inclusion from the 4.4BSD-Lite2 code base too), developed at the University of California, Berkeley, under the authorization of the Computer Systems Research Group (CSRG), Computer Science Division, Department of Electrical Engineering and Computer Science at Berkeley. FreeBSD operating system (just like a Linux distribution) comes with a whole set of packages, including user applications, tools, user utilities, shells, games, documentation, developer utilities, system and user-level binaries and full source code for the operating systems. The FreeBSD Project web-site can be accessed at: http://www.freebsd.org.</para>
<para>
Recently, a lot of media spotlight has put the GNU/Linux system (more specifically the Linux Kernel) in a stardom status. Some rate Linux as the best ever written UNIX-clone that would spell disaster for UNIX and other UNIX-clones and UNIX-compatibles out there in the market. But in reality it is not so. Readers must note: Just as the power of an automobile comes from the quality of the engine running under it's hood, similarly features like stability, reliability, extensibility and robustness of an operating system software comes from the internal structure of the Kernel or the core of that corresponding operating system. I personally feel that both the Linux and the FreeBSD Kernel are great works of creativity and tremendous effort and just a user-level or technical comparison between the two is meaningless. Situations where memory is a scarcity and moreover gets crunched and stressed upon real hard, the Linux Kernel breaks down. FreeBSD with it's highly optimized and advanced VM/Swap system comes to the rescue! On the other hand, under given situations, Linux may outperform FreeBSD by a mile. The significant point for readers to note and remember is that the Linux Kernel favors simplicity over highly optimized and dynamic yet more complex code whereas the FreeBSD Kernel optimizes performance by introducing more complex code and heavily optimizing the code base by rearranging and rewriting some of the more important internal algorithms and data structures from time to time.</para>
<para>
A complete and exhaustive discussion on Linux and FreeBSD Kernels is beyond the scope of this guide. If readers find it interesting, they may search the Internet for more Linux and/or FreeBSD specific information. I would suggest the readers to read "Understanding the Linux Kernel" by Bovet and Cesati for getting more in-depth information on the inner-workings of the Linux Kernel, "The Design and Implementation of the 4.4BSD Operating System" for FreeBSD/OpenBSD and so on, and "The Design of the UNIX Operating System" by M. Bach for UNIX SVR4 internals.</para>

<title>
OpenBSD</title>
<para>
The BSD family, other than the dominant big-brother FreeBSD, also consists of OpenBSD, NetBSD, BSD/OS and Darwin operating systems. OpenBSD is a fully functional, multi-platform UNIX-like Operating System based on Berkeley Networking Release 2 (Net/2) and 4.4BSD-Lite. The OpenBSD team strives to achieve what is called "a secure by default" status. This means that an OpenBSD user should feel safe that their newly installed machine will not be compromised. This "secure by default" goal is achieved by taking a proactive stance on security. FreeBSD -RELEASES target stability and reliability under the most adverse of conditions whereas OpenBSD -RELEASES target optimum security in corporate environments. The OpenBSD operating system software has been labeled "the proactively secure Unix-like operating system". The OpenBSD Kernel is heavily optimized with security features thereby providing customers with utmost secure and hack-resilient real-time systems. The OpenBSD Project web-site can be accessed at: http://www.openbsd.org.</para>
<para>
The OpenBSD operating system software has integrated strong cryptography into the base system. A fully functional IPsec (Internet Protocol Security) implementation is provided as well as support for common protocols such as SSL (Secure Sockets Layer) and SSH (Secure Shell). Network filtering and monitoring tools such as packet filtering, NAT (Network Address Translation), and bridging are also included. For high performance demands, support for hardware cryptography has also been added to the base system. OpenBSD provides as many security options as possible to allow the user to enjoy secure computing without feeling burdened by it.</para>
</section>
<section>
<title>
NetBSD</title>
<para> The NetBSD kernel focuses on clean design and well architected solutions. NetBSD supports a massive range of hardware platforms from a single source tree, including simultaneous release across all platforms, and continues to attract users and experienced developers despite lack of media exposure and commercial backing - all thanks to attention to code quality. The NetBSD operating system kernel targets "portability" and tries to run on as many platforms as possible. The NetBSD Project web-site can be accessed at: http://www.netbsd.org</para>

<para>One can use the Windows fdisk and format tools for partitioning a new unformatted hard disk. I have assumed that the reader has a new unformatted hard disk which he/she wishes to partition and then format for installing a Microsoft Windows operating system. The material mentioned right below applies to Microsoft Windows 95, Microsoft Windows 98 (SE) and Microsoft Windows Millennium (ME). If you plan to install Windows NT, Windows 2000 or Windows XP, then skip this section and go to the part referring to sections D, E and F.</para>

The material mentioned below applies to Microsoft Windows 95, Microsoft Windows 98 (SE) and Microsoft Windows Millennium (ME). Thus, if you are installing any one of these, make sure you read through all the content mentioned herein which describes the Fdisk and Format tools and explains how to use them to partition or repartition a hard disk. The material describes the following topics:</para>

<para>How to Partition and Format a Master Hard Disk</para>
</listitem>
</itemizedlist>
<para>
Before you install your operating system, you must first create a primary partition on the hard disk (disk 1) on your computer, and then format a filesystem on that partition. The Fdisk tool is an MS-DOS-based tool that you can use to prepare (partition) a hard disk. You can use the Fdisk tool to create, change, delete, or display current partitions on the hard disk, and then each allocated space on the hard disk (primary partition, extended partition, or logical drive) is assigned a drive letter. Disk 1 may contain one extended partition, and a second hard disk may contain a primary or extended partition. An extended partition may contain one or more logical MS-DOS drives.</para>
<para>
After you have used the Fdisk tool to partition the hard disk, you can use the Format tool to format those partitions with a filesystem. The filesystem File Allocation Table (FAT) allows the hard disk to accept, store and retrieve data. Windows 95, Windows 98 (SE), Windows Millennium (ME) and Windows 2000 support the FAT16 and FAT32 filesystems. When you run the Fdisk tool on a hard disk that is larger than 512 megabytes (MB), you are prompted to choose one of the following file systems: FAT16 or FAT32. The FAT16 filesystem has a maximum of 2 gigabytes (GB) for each allocated space or drive letter. For example, if you use the FAT16 filesystem and have a 6-GB hard disk, you can have three drive letters (C, D, and E), each with 2 GB of allocated space. As for the FAT32 filesystem, it supports drives that are up to 2 terabytes in size and stores files on smaller sections of the hard disk than the FAT16 filesystem does. This results in more free space on the hard disk. Please note that the FAT32 filesystem does not support drives that are smaller than 512 MB. When you run the "fdisk" and "format" commands, the Master Boot Record (MBR) and file allocation tables are created. The MBR and file allocation tables store the necessary disk geometry that allows hard disk to accept, store, and retrieve data.</para>
<para>
Please note that I have assumed that you own a computer system which can run without glitches and that you have access to a bootable Microsoft Windows CD-ROM. If you do run into problems booting from the CD-ROM or using Start-up disks, please consult your hardware manufacturer to obtain the CD-ROM device driver(s). For partitioning a master hard disk, you have to run the fdisk command. First insert the Startup disk in the floppy disk drive, restart your computer, and then use one of the following methods, depending on your operating system.</para>
<section>
<title>For a Windows 95/98/ME Startup disk</title>
<para>At a command prompt, type fdisk, and then press enter. If your hard disk is larger than 512 MB, you receive the following message: Your computer has a disk larger than 512 MB. This version of Windows includes improved support for large disks, resulting in more efficient use of disk space on large drives, and allowing disks over 2 GB to be formatted as a single drive.</para>
<para>
If you enable large disk support and create any new drives on this disk, you will NOT be able to access the new drive(s) using other operating systems, including some versions of Windows 95 and Windows NT, as well as earlier versions of Windows and MS-DOS. In addition, disk utilities that were not designated explicitly for the FAT32 file system will not be able to work with this disk. If you need to access this disk with other operating systems or older disk utilities, do not enable large drive support.</para>
<screen>Do you wish to enable large disk support?</screen>
<para>
If you want to use the FAT32 file system, press Y and then press enter. If you want to use the FAT16 file system, press N, and then press enter. After you press enter, the following Fdisk Options menu is displayed:</para>
<screen>
1. Create DOS partition or Logical DOS Drive
2. Set active partition
3. Delete partition or Logical DOS Drive
4. Display partition information
5. Change current fixed disk drive

<title>For a FAT32 File System</title>
<para>If you press Y for the FAT32 file system (in step 2) and you want all of the space on the hard disk to be assigned to drive C, press Y, and then press enter. Press ESC, and then press ESC to quit the Fdisk tool and return to a command prompt.</para>
</section>
<section>
<title>For a FAT16 File System</title>
<para> If you press N for the FAT16 file system (in step 2), you can accept the default 2 GB size for the partition size, or you can customize the size of the partition.</para>
</section>
</section>
<section>
<title>Customizing partition size</title>
<para>
If you want to customize the size of the partitions (drive letters) on the hard disk, press N, and then press enter. A dialog box is displayed in which you can type the size that you want for the primary partition in MB or percent of disk space. Note that for computers that are running either Windows 98 (SE) or Windows ME, Microsoft recommends that you make the primary partition at least 500 MB in size. Type the size of the partition that you want to create, and then press enter. Press ESC to return to the Options menu. To assign drive letters to the additional space on the hard disk, press 1, and then press enter. Press 2 to select the Create Extended DOS Partition menu option, and then press enter. You receive a dialog box that displays the maximum space that is available for the extended partition. You can adjust the size of the partition or use the default size. Note that the default maximum space is recommended, but you can divide the space between multiple drive letters. Type the amount of space that you want, press enter, and then press ESC. The Create Logical DOS Drive(s) in the Extended DOS Partition menu is displayed. This is the menu that you can use to assign the remaining hard disk space to the additional drive letters. Type the amount of space that you want to assign to the next drive letter in the Enter logical drive size in Mbytes or percent of disk space (%) box, and then press enter. After this, you have to activate the partition from which you plan to boot. This, usually is the drive C. So, press 2 to select the Set active partition menu option, and then enter the number of the partition you want to make active.</para>
</section>
<section>
<title>Format Partition</title>
<para>After you create the partitions, you must format the partitions for accessing and using them. If you are using a Windows 95 Startup disk, a command prompt is displayed and you can skip to step 2. If you are using a Windows 98 Second Edition or a Windows ME Startup disk, select the Start computer without CD-ROM support menu option when the Windows 98 Startup menu is displayed. When a command prompt is displayed, type "format c:", and then press enter This command formats drive C (or your "active" drive). For all other partitions, type format drive: (where drive is the letter of the partition that you want to format).</para>
<warning>
<para>
Readers must note that I speak about "partitioning a hard disk" using Microsoft fdisk utility in general here in this section in order to provide the absolute newbies with general information on how to partition and format a new hard disk drive.</para>

For installing any one of these 3 above-mentioned operating systems, first use fdisk tool to partition your hard disk. Then comes to choosing the filesystem type.</para>
<para>
During a new installation of Windows NT, 2000 or XP, you may have to choose which file system your computer should use. On my other PC, I personally use Microsoft Windows XP Professional which supports:
</para>
<para>FAT32: An enhanced version of the file allocation table (FAT) system that is standard on all Windows operating systems starting with later (32-bit) versions of Windows 95. The FAT32 system can be used on large hard disks, from 512 megabytes (MB) to 32 gigabytes (GB).</para>
<para>
NTFS: The NT file system (NTFS) is used with the Windows NT, Windows 2000, and Windows XP operating systems. NTFS provides enhanced reliability, stability, and security, and supports large hard disks of up to 2 terabytes (TB).</para>
<para>
But very "important" information: The conversion to NTFS is one-way only; if you convert your FAT or FAT32 file system to NTFS you cannot convert your hard disk back to FAT later.</para>
<para>
If you are not sure which file system to use, I would suggest using FAT32. If you want to change your file system, here are a few recommendations:</para>
<itemizedlist>
<listitem>
<para>Use FAT32 if your hard disk is smaller than 32 GB.</para>
</listitem>
<listitem>
<para>Use FAT32 if you want to install more than one operating system on your computer.</para>
</listitem>
<listitem>
<para>Use NTFS if your hard drive is larger than 32 GB and you are running only one operating system on your computer.</para>

<para>Use NTFS if you want enhanced file security.</para>
</listitem>
<listitem>
<para>Use NTFS if you need better disk compression.</para>
</listitem>

<para>
You can choose any filesystem type that you wish. After choosing the filesystem, proceed with the Windows NT/2000/XP installation normally. After installation, feel free to configure your new system.</para>

<section>
<title>Summary of the actual steps</title>
<para>
Enough said about the different Microsoft operating systems. Now let us look more closely how exactly we would partition the hard disk. As mentioned above, we use Microsoft fdisk, then create a Primary DOS Partition of about 2000MB or so. On my PC, I have a primary partition of 999MB which contains Microsoft Windows 98 (SE). I have used such a small space cause I hardly do any work on Windows thereby reserving space for FreeBSD and Linux! Readers can choose a bit more space if they feel like doing so. After creating this partition, do not forget to format it using the Format tool. On my system, I have a FAT32 Primary partition.</para>
<para>
After creating this Primary Partition (suppose say, of 999MB), we do not (I repeat: do not) need to create any more partitions using Microsoft fdisk utility. For example, I have a 20.0 GB Maxtor HDD. I create a primary partition of about 1000MB using fdisk. The obvious question from the reader is: What about the rest 19GB? What happens to it? Well the answer is simple. I leave it untouched because I would be dividing this available space into 2 halves for installing FreeBSD or OpenBSD or NetBSD and Linux while using the FreeBSD Partition editor or OpenBSD Partition editor or NetBSD partition editor respectively while installing FreeBSD 5.1-RELEASE or OpenBSD 3.2-RELEASE or NetBSD 1.6.1. So, no need to worry absolutely and just take the ride with me. I promise, by the time you are done reading this guide, not a single MB on your hard disk will be wasted.</para>
<para>
Thus, before we finally move on to the next section where we install
and configure FreeBSD 5.1-RELEASE or OpenBSD 3.2-RELEASE or NetBSD
1.6.1, I would like to round-off this chapter with a "Partition
check". I have the following partition table on my computer after this
step (as observed from Microsoft fdisk):</para>
<screen>
Display Partition Information Partition
Status Type Volume_Label Mbytes System Usage
C:1 A PRI DOS WIN 1000 FAT32 5%
</screen>
<para>
Once this done, reboot your computer and using a bootable Microsoft Windows CD-ROM (depending on your operating system of choice), install the operating system as usual. Do the usual system configuration and log into Windows to check whether everything works fine. That is all for this section, now take a break, have a coffee and proceed to the next chapter, Chapter 3: Installing FreeBSD 5.1-RELEASE.</para>
</section>
</chapter>
<chapter>
<title>
Installing FreeBSD 5.1-RELEASE</title>
<para>This Chapter focuses on installing FreeBSD 5.1-RELEASE and multi-booting the system so that it can coexist successfully with the already existing Windows operating system on the computer. Like the Windows installation, it too focuses on a CD-ROM based installation. Experts may proceed as usual without help, as for the newbies out there, make sure you check out the Frequently Asked Questions for FreeBSD 2.X, 3.X and 4.X at the "The FreeBSD Documentation Project" at http://www.freebsd.org. For a step-by-step FreeBSD Installation procedure with screenshots, please refer to Chapter2 : Installing FreeBSD of the FreeBSD Handbook at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html. These and other documentation available on the FreeBSD Project homepage provides exhaustive and extensive coverage of all aspects related to the FreeBSD software. Make sure you grab as much information as you can from this site before proceeding with this guide.</para>
<para>Readers must note that at the time of writing, 2 parallel branches of the FreeBSD operating system exist. The latest -STABLE release is the FreeBSD 4.9-RELEASE while the latest -CURRENT release is the FreeBSD 5.1-RELEASE. In this Chapter, we would discuss some theoretical aspects of installing FreeBSD 5.1-RELEASE, disk partitioning (better known as slicing in FreeBSD terminology) and then move on to the actual installation itself.

<title>Slicing in FreeBSD</title>
<para>
Before installing FreeBSD, it would be a good idea to take a brief tour of what FreeBSD calls "slicing". If you already know this stuff, feel free to skip this part and read the section entitled "Summary of Installation Steps".</para>
<para>The FreeBSD operating system partitions (a hard disk) and labels partitions according to a particular chosen scheme which is similar to other BSD-based UNIX systems such as NetBSD, OpenBSD, Ultrix, Digital Unix and SunOS. Let us see how the FreeBSD software "slices" your hard disk and then "creates partitions in it" for use. Each partition-that-contains-a-filesystem is stored in what FreeBSD calls a "slice". Slice is FreeBSD's term for what were earlier called partitions. Slices are numbered, starting at 1, through to 4 (In Windows terminology, they would be called "primary partitions", starting at 1, through to 4). Thus, the reader must note that "a primary partition" in Windows refers to a "slice" in FreeBSD terminology, and "an extended partition containing logical disk drives in it" is simply called as "partitions" in FreeBSD. A logical disk drive within an extended partition may also be called as "a logical slice inside a physical slice" in FreeBSD. It may appear a bit awkward at times, but the sooner the reader gets used to these terms, the better!</para>
<para>
Now, the important part. There exists a few operating systems which can boot even if their corresponding boot files are stored within a logical disk drive of an extended partition. For FreeBSD, this mechanism does "not" work. FreeBSD necessarily needs one of the slices (that is the 4 entries in the partition table on your computer's hard drive, which in Windows terminology would be called as a "primary partition"). It then uses a program called "disklabel" for making upto eight partitions in this slice. Readers must note a very significant fact: You "cannot" install FreeBSD in an extended partition made by Linux (or DOS).</para>
<para>
FreeBSD labels hard disks and partitions as follows:
<itemizedlist>
<listitem>
<para>First IDE hard disk (Primary Master) - /dev/ad0</para>
</listitem>
<listitem>
<para>Second IDE hard disk (Primary Slave) - /dev/ad1</para>
</listitem>
<listitem>
<para>Third IDE hard disk (Secondary Master) - /dev/ad2</para>
</listitem>
<listitem>
<para>Fourth IDE hard disk (Secondary Slave) - /dev/ad3</para>
</listitem>
</itemizedlist>
where, /dev is the directory under the root ("/") directory in FreeBSD which contains all the device special files associated with devices. I assume readers are using a FreeBSD 4.X-RELEASE or later. IDE hard disks are named as wd* before FreeBSD 4.0-RELEASE.</para>
<para>
What about SCSI drives? Well, FreeBSD labels that too!
<itemizedlist>
<listitem>
<para>
First SCSI hard disk (Primary Master) - /dev/da0</para>
</listitem>
<listitem>
<para>Second SCSI hard disk (Primary Slave) - /dev/da1</para>
</listitem>
<listitem>
<para>
Third SCSI hard disk (Secondary Master) - /dev/da2</para>
</listitem>
<listitem>
<para>Fourth SCSI hard disk (Secondary Slave) - /dev/da3</para>
</listitem>
</itemizedlist>
where, /dev is the directory under the root ("/") directory in FreeBSD which contains all the device files associated with devices.</para>
<para>
Now, let us talk about the partitioning scheme under FreeBSD. It is just like in Linux, only the way the partitions are named is different. In FreeBSD, we first consider a particular hard disk, whether IDE or SCSI. Then, we consider the partitions on it. For example, the partitions on an IDE drive are named in the following way (/dev/ad0 is used as an example):<itemizedlist>
<listitem>
<para>First primary partition - /dev/ad0s1</para>
</listitem>
<listitem>
<para>
Second primary partition - /dev/ad0s2</para>
</listitem>
<listitem>
<para>Third primary partition - /dev/ad0s3</para>
</listitem>
<listitem>
<para>Fourth primary partition - /dev/ad0s4</para>
</listitem>
</itemizedlist></para>
<para>
These above mentioned drives may contain partitions as well. FreeBSD labels them too and each label has it's own corresponding mount point too. Let us consider an example. A computer has /dev/ad0 as its hard disk named, contains 2 slices; the first slice is a FAT32 partition and the second a BSD/i386 partition containing 4 logical slices [logical disk drives] in it. So, in this case, how would the partition table look like and mean? Let us see how FreeBSD labels this scheme. FreeBSD would represent this as:
<itemizedlist>
<listitem>
<para>
/dev/ad0</para>
<itemizedlist>
<listitem>
<para>/dev/ad0s1</para>
</listitem>
<listitem>
<para>/dev/ad0s2</para>
<itemizedlist>
<listitem>
<para>/dev/ad0s2a</para>
</listitem>
<listitem>
<para>/dev/ad0s2b</para>
</listitem>
<listitem>
<para>dev/ad0s2e</para>
</listitem>
<listitem>
<para>/dev/ad0s2f</para>
</listitem>
</itemizedlist>
</listitem>
</itemizedlist>
</listitem>
</itemizedlist>
where, ad0s2a refers to the "first partition (a) on the second slice (s2) on the first IDE disk (ad0)". In the above example, /dev/ad0s1 is the slice containing FAT32 filesystem and /dev/ad0s2 is the second slice on the hard disk drive under scrutiny. Readers must note that FreeBSD labels slices from /dev/ad0s1 onwards to /dev/ad0s4, with a maximum of 8 possible logical slices named as a, b, c, d, e, f, g and h. In this example, the "logical slices" a, b, e and f have their corresponding mount points in FreeBSD.</para>
<para>
Here, the mount points are as follows:<itemizedlist>
<listitem>
<para>a = / (the root directory)</para>
</listitem>
<listitem>
<para>b = swap filesystem</para>
</listitem>
<listitem>
<para>e = /var</para>
</listitem>
<listitem>
<para>f = /usr</para>
</listitem>

<title>Filesystems in FreeBSD</title>
<para>
Microsoft Windows operating systems use FAT16, FAT32, NTFS 4.0 and NTFS 5.0 filesystems for storing and retrieving data. The recently released NTFS 5.0 is implemented in all of the Windows 2000 operating systems. The Linux Kernel uses the "Third Extended native filesystem", denoted as ext3fs. Linux also supported the ext (now obsolete and no longer supported) and ext2 filesystems. The "Second Extended filesystem" (ext2fs) is an advanced hierarchical filesystem developed for the Linux operating system, which included advanced features like a maximum file size of 2.0 GB, a maximum file name length of 255 characters and support for three time/date stamps. They are the date of creation, date of last modification and date of last access. The "Third Extended filesystem" has all these features, and additionally it implements IBM's "journaled file system architecture" (JFS) functionality. The JFS architecture ensures the integrity of data stored on a hard disk in the event of an unplanned shutdown, such as one caused by a power outage. A journaled filesystem maintains a log of all read and write events; this log enables the disk to be restored to its last stable state and additionally allows incompletely written data to be restored to the maximum possible extent.</para>
<para>
The FreeBSD operating system basically uses the UNIX File System (UFS) architecture for its underlying filesystem. The University of Berkeley made more advancements to it referred to as the "Berkeley Improvements" or "Berkeley Extensions". This filesystem, currently used by FreeBSD as its native filesystem is often called the "Fast Filesystem" or FFS, because access reads and writes to data stored in FFS is very fast. The architecture is a little more complex than Linux's ext2fs. It offers a better way to insure filesystem data integrity, mainly with the "softupdates" option. This option decreases synchronous I/O and increases asynchronous I/O because writes to a UFS filesystem are not synced on a sector basis but according to the filesystem structure. This ensures that the filesystem is always coherent between two updates.</para>
<para>
The FreeBSD filesystem also supports file flags, which can stop a would-be intruder dead in his or her tracks. There are several flags that you can add to a file such as the immutable flag. The immutable (schg) flag would not allow any alteration to the file or directory unless you remove it. Other available flags are append only (sappnd), cannot delete (sunlnk), and archive (arch). When you combine these with the kernel security level option, you have a very impenetrable system. In short, the FreeBSD Kernel uses UFS = UFS+FFS+Softupdates+dirpref+dirhash functionality for storing and retrieving data on disks. </para>

<title>Summary of Installation Steps</title>
<para>
The partitioning scheme and filesystems covered in FreeBSD, its time for us to move on to the actual FreeBSD installation. For a complete step-by-step coverage of FreeBSD installation, please consult the installation guide available on the FreeBSD Project web site. As in the previous Chapter, here also, I would be mentioning only the significant steps for the installation. Use these steps to install FreeBSD on your computer and configure it for "multi-booting":<orderedlist>
<listitem>
<para>We have a computer running a Microsoft Windows operating system. On my PC, it is Windows 98 (SE). I put a bootable FreeBSD 5.1-RELEASE CD-ROM in the CD-ROM drive and reboot the system.</para>
</listitem>
<listitem>
<para>
The computer boots, reads the CD-ROM, displays the usual hardware probing messages and presents you with a screen where you can choose from a list of options. Proceed to the FreeBSD System Installation and Configuration Utility. In FreeBSD it is called the /stand/sysinstall utility.</para>
</listitem>
<listitem>
<para>
Once the /stand/sysinstall screen appears, select a Novice, Custom or Express install. I choose the Custom installation because it provides the optimum flexibility. For novice users, I would suggest using the Recommended installation. Proceed as usual until you reach the FreeBSD Fdisk editor.</para>
</listitem>
<listitem>
<para>
Select the unused space and create 2 approximately equal partitions. Thus, 2 slices would be created (in addition to the one that already exists). One would be used for installing FreeBSD and the other for Red Hat Linux later. Readers with intermediate and/or expert FreeBSD knowledge should find this easy to do. After creating these 2 partitions, there should be no free space on your hard disk. Exit saving all the changes and proceed as usual to the FreeBSD Disk label editor. Readers must note: While creating the Linux slice, the filesystem ID should be 131. This creates a Linux native filesystem (ext2fs filesystem). Otherwise, the default FreeBSD UFS filesystem would be created.</para>
</listitem>
<listitem>
<para>
The next screen allows you to install a boot manager. Since Microsoft Windows 98 (SE) overwrites the Master Boot Record (MBR) rendering any other operating system unbootable, you should choose to install the FreeBSD boot manager in the MBR of your hard disk. I have installed FreeBSD alongside another operating system on the same hard disk, and I want FreeBSD to boot the other operating system when I start the computer. That is the reason, I installed the FreeBSD boot manager into the MBR. Once done, we enter the Sysinstall Disklabel Editor.</para>
</listitem>
<listitem>
<para>The Sysinstall Disklabel Editor represents the already existing Windows FAT32 partition. Readers must note that FreeBSD names this partition as a FreeBSD slice but without an appropriate "mount point". Here, I would create the logical partitions for the FreeBSD slice (which is /dev/ad0s2).</para>
</listitem>
<listitem>
<para>On my PC, the Windows FAT32 partition is named /dev/ad0s1 (C: in DOS). In other words, it is the first slice on the IDE hard disk of my computer. Disklabel can automatically create partitions for you and assign them default sizes if you press the key A. Depending on the size of the disk (and purpose of installing FreeBSD), the defaults may or may not be appropriate. For me, it works most of the time! To quote from the FreeBSD Handbook, "...Beginning with FreeBSD 4.5, the default partitioning assigns the /tmp directory its own partition instead of being part of the / partition. This helps avoid filling the / partition with temporary files...". This is an important consideration if you have a lot of temporary files to deal with. I create a /, swap, /usr, /var and other usual partitions in my FreeBSD slice (named as /dev/ad0s2).</para>
</listitem>
<listitem>
<para>Once the slices created and partitions within the FreeBSD slice set and done, we proceed to choose what to install on the system. Depending on the intended use and resources at your disposal, you must make the correct choice of what to install and what not to install. For example, Mr. A wants to check out FreeBSD 5.1-RELEASE for fun! Well, a "Minimal Install" is the best choice for him. It saves him both time and hard disk space. His brother, Mr. B is a hot-shot Kernel Developer. He wants access to documentation, full system binaries and the Kernel source code. He would go in for a "Kern-Developer" canned distribution set. And if you have enough resources at your disposal or if it so happens you do not want to use the pkg_add tool to install packages later or from the ports collection manually, well, as it so happens, you can always go in for the "All" install option. This would install everything on the system. Thus, we see that the predefined options range from installing the smallest possible configuration (Minimal) to everything (All). Those who are new to UNIX and/or FreeBSD should almost certainly select one of these canned options. Readers must note: If a graphical user interface (GUI) is desired then a distribution set that is preceded by an X should be chosen. The configuration of XFree86 and selection of a default desktop is part of the post-installation steps.</para>
</listitem>
<listitem>
<para>Next, choose the installation media from the list of available choices. I guess you are doing a Local CD/DVD-ROM installation just like me! Using the arrow keys highlight "Install from a FreeBSD CD/DVD", and press Enter to proceed with the installation. If it so happens that you want to undertake a different kind of installation, choose the appropriate option and follow the steps.
10. Next appears the "Committing to the Installation" screen. You would be asked whether you are sure of installing FreeBSD on this system or not. Select [ Yes ] and press enter to proceed. The installation can now proceed if desired. Readers must note: This is absolutely the last chance for aborting the installation to prevent changes to the hard disk.
11. The installation time will vary according to the distribution chosen, installation media used, and the speed of the computer. There will be a series of messages displayed indicating the status. The installation is complete when the following message is displayed: "Congratulations! You now have FreeBSD installed on your system....".
12. Next comes the post-installation steps. It usually involves chores as "Network Device Configuration", "Configure Gateway", "Configure Internet Services", "Anonymous FTP", "NFS Server", "NFS Client", setting up a "Security Profile", "System Console Settings", "Setting The Time Zone", "Adding Users and Groups" and so on. For an exhaustive covering of each and every step along with helpful screenshots, please refer to the FreeBSD Handbook at http://www.freebsd.org.
13. Once you have completed the post-installation steps, exit the /stand/sysinstall system installer utility, take out the CD-ROM, and reboot the system. When your computer reboots, since you have installed the FreeBSD boot loader into the MBR of your hard disk, you would normally get a following prompt on your screen. It displays something like: F1 DOS, F2 FreeBSD, F3 Linux; each one in a separate line. The Default: F1 is also shown. FreeBSD uses a 3-stage bootstrap by default, and this is actually the preceding bootblock, named /boot/boot0, which lives on the MBR, the special part of the disk that the system bootstrap looks for and runs, and it simply shows a list of possible slices to boot from.
14. Press F1 to boot into Microsoft Windows. On my computer, I successfully booted into Windows 98 (SE). So far so good! I rebooted and pressed F2 this time, and I successfully booted into FreeBSD as well. Bingo! You already have a dual-boot system which uses the FreeBSD boot loader to boot 2 operating systems.
15. Depending on the configuration of your computer, you will receive bootup messages on your screen when you boot into FreeBSD for the first time. Though the messages scroll off the screen rather fast for you to read anything productive, you can always read it later by using the "/sbin/dmesg | more" command. Finally, you will arrive at the login prompt. Login using the username/password you set during installation. Readers must note: The Linux slice is not ready yet, cause we have not defined the mount points of the root (/) directory and swap filesystem as well. So, for doing this and more, we proceed to the chapter, Chapter 6: Installing Red Hat Linux 8.0 (Psyche). Readers must note that if you have already installed FreeBSD, you can skip the next 2 chapters and proceed with the Linux installation directly.
