|
|
<P>This section is written by Dr. Tilmann Bubeck,

|

<P>
|
|
<P>I tried hard to install a laptop through PLIP with a RedHat 6.2 but
|
|
the installer from RedHat is buggy and could not be used for
|
|
PLIP. I verified that it was already broken in RedHat 6.1, but
|
|
works in RedHat 5.2 as desired. Patches have been sent to RedHat
|
|
and will hopefully be applied to the upcoming RedHat 7.0.
|
|
<P>So if you want to install a RedHat 6.x over PLIP you <B>must</B>
|
|
follow these instructions.
|
|
<P>The problem is the "bootnet" disk. This disk should be used for
|
|
PLIP installation but has 2 serious errors:
|
|
<P>
|
|
<UL>
|
|
<LI>it does not contain the necessary driver "parport_pc"</LI>
|
|
<LI>it does not allow you to specify important module
|
|
parameters to "parport_pc" (especially "iobase" and "irq").</LI>
|
|
</UL>
|
|
<P>
|
|
<H2><A NAME="ss15.1">15.1 Using a fixed "bootnet" disk</A>
|
|
</H2>
|
|
|
|
<P>Probably the easiest way to solve the above problem is to use a
|
|
fixed "bootnet" disk. You can get a fixed "bootnet" disk for RedHat
|
|
6.2 from
|
|
<A HREF="http://www-ti.informatik.uni-tuebingen.de/~bubeck/bootnet-plip-62.img">http://www-ti.informatik.uni-tuebingen.de/~bubeck/bootnet-plip-62.img</A><P>Use the following command to copy the downloaded image to an empty disk:
|
|
<P><CODE>dd if=bootnet-plip-62.img of=/dev/fd0</CODE>.
|
|
<P>Then insert the disk and turn your computer on. When you come to
|
|
the point where you must choose your network device driver please
|
|
do:
|
|
<P>
|
|
<UL>
|
|
<LI>1- Choose "Parallel Port Module for PC" and select "specify
|
|
module parameters".
|
|
</LI>
|
|
<LI>2- Enter iobase and interrupt for your parallel
|
|
port. Typical values are iobase=0x378 or iobase=0x3bc. Interrupt most
|
|
often is "irq=7".
|
|
</LI>
|
|
<LI>3- Validate that the kernel loads the module and finds the
|
|
parallel port. Use ALT+F4 to switch to kernel messages and look
|
|
for a line saying: "parport: ... irq: 7".
|
|
</LI>
|
|
<LI>4- The installation will then try to access the network
|
|
which is still not available. So the installer asks again for the
|
|
installation method. Choose your method again.
|
|
</LI>
|
|
<LI>5- Now choose the "plip" module without any
|
|
parameters. Again verify the loading of the module in the kernel
|
|
messages.
|
|
</LI>
|
|
<LI>6- Network should be up and running, installation should
|
|
proceed. If not, then check the modules parameters to
|
|
"parport_pc".</LI>

<H2><A NAME="ss15.2">15.2 Building your own "bootnet" disk</A>
|
|
</H2>
|
|
|
|
<P>If the above bootnet disk is not suitable for your needs, I will
|
|
present a small description of how to transform a standard bootnet
|
|
disk for using "plip". This description is quite short and is
|
|
addressed to the advanced user.
|
|
<P>
|
|
<UL>
|
|
<LI>1- make a copy of the standard bootnet disk by using "dd".
|
|
</LI>
|
|
<LI>2- insert this copy of standard bootnet disk and mount it
|
|
with: <CODE>mount /dev/fd0 /mnt</CODE>
|
|
</LI>
|
|
<LI>3- gunzip initial ramdisk with <CODE>cp /mnt/initrd.img
|
|
/tmp/initrd.img.gz; gunzip /tmp/initrd.img.gz</CODE>
|
|
</LI>
|
|
<LI>4- Mount initial ramdisk with <CODE>mkdir /mnt2; mount -o loop
|
|
/tmp/initrd.img /mnt2</CODE>
|
|
</LI>
|
|
<LI>5- gunzip and extract modules directory with: <CODE>cd /tmp;
|
|
zcat /mnt2/modules/modules.cgz | cpio -ivd</CODE>
|
|
</LI>
|
|
<LI>6- You should now have a directory called with your kernel
|
|
version number (e.g. "2.2.14-5.0BOOT") containing a lot
|
|
of modules. Check if the modules "parport_pc.o" is
|
|
included in this directory (it is unfortunately NOT
|
|
included in RedHat 6.0-6.2). If you can not find it, then
|
|
please build a custom kernel with the EXTRAVERSION number
|
|
like your bootnet disk (in this case: "5.0BOOT") and
|
|
"parport" support as module. Copy the newly created
|
|
parport_pc.o module to your new modules directory: <CODE>cp
|
|
.../parport_pc.o /tmp/2.2.14-5.0BOOT</CODE>.
|
|
</LI>
|
|
<LI>7- delete a normally unused module, so that you have
|
|
additional space on the disk: <CODE>rm
|
|
/tmp/2.2.14-5.0BOOT/sktr.o</CODE> (driver for token ring
|
|
network adapter).
|
|
</LI>
|
|
<LI>8- rebuild modules archive with: <CODE>find
|
|
/tmp/2.2.14-5.0BOOT | cpio -ov -H crc | gzip >
|
|
/mnt2/modules/modules.cgz</CODE>
|
|
</LI>
|
|
<LI>9- insert a new modules dependency line into modules.dep
|
|
saying that module "parport_pc" needs module "parport":
|
|
<CODE>echo "parport_pc: parport" >>
|
|
/mnt2/modules/modules.dep</CODE>
|
|
</LI>
|
|
<LI>10- insert entry for parport_pc module into module-info so
|
|
that the user can select the parport_pc module during
|
|
installation. Append the following text to the end of
|
|
/mnt2/modules/module-info:
|
|
<PRE>
|
|
parport_pc
|
|
plip
|
|
"Parallel Port Module for PC"
|
|
io "Base I/O address"
|
|
irq "IRQ level"
|
|
</PRE>
|
|
|
|
|
|
</LI>
|
|
<LI>11- unmount and gzip initial ramdisk with: <CODE>umount /mnt2;
|
|
gzip -9 /tmp/initrd.img</CODE>
|
|
</LI>
|
|
<LI>12- copy initial ramdisk to bootnet disk and unmount: <CODE>cp /tmp/initrd.img.gz /mnt/initrd.img; umount /mnt</CODE></LI>
|
|
</UL>
|
|
<P>By following these instructions, you get a bootnet disk containing
|
|
all necessary modules and therefore allowing for a PLIP
|
|
installation. Please follow the instructions elsewhere in this how-to
|
|
on how to do the installation with the new disk.
