<P>Next, I installed Windows-95 on my office system. It blew away my nice
Lilo MBR, but it left my Linux partitions alone. Kernels take a long
time to load from floppy, so I made a floppy with a working Lilo setup
on it, which could boot my kernel from the IDE.</P>
<P>I made the lilo floppy like so:
<PRE>
fdformat /dev/fd0H1440 # lay tracks on virgin diskette
mkfs -t minix /dev/fd0 1440 # make file system of type minix
mount /dev/fd0 /mnt # mount in the standard tmp mount point
cp -p /boot/chain.b /mnt # copy the chain loader over
lilo -C /etc/lilo.flop # install Lilo and the map on the diskette.
umount /mnt
</PRE>
</P>
<P>Notice that the diskette <B>must be mounted when you run the
installer</B> so that Lilo can write its map file properly.</P>
<P>This file is /etc/lilo.flop. It's almost the same as the last one:</P>
<P>
<PRE>
# Makes a floppy that can boot kernels from HD.
boot = /dev/fd0
map = /mnt/lilo-map
delay = 100
ramdisk = 0
timeout = 100
prompt
disk = /dev/hda # 1 GB IDE, BIOS only sees first 500 MB.
bios=0x80
sectors = 63
heads = 16
cylinders = 2100
image = /vmlinuz
append = "hd=2100,16,63"
root = /dev/hda2
label = linux
read-only
vga = extended
other = /dev/hda1
label = msdos
table = /dev/hda
loader = /mnt/chain.b
</PRE>
</P>
<P>Finally, I needed MS-DOS 6.2 on my office system, but I didn't
want to touch the first drive. I added a SCSI controller and
drive, made an msdos file system on it with Linux' mkdosfs, and
Windows-95 sees it as "D:". But of course MSDOS will not boot
off of D:. This is not a problem when you have Lilo. I added
the following to the <CODE>lilo.conf</CODE> in Example 2. </P>
<P>
<PRE>
other = /dev/sda1
label = d6.2
table = /dev/sda
loader = /boot/any_d.b
</PRE>
</P>
<P>With this modification MSDOS-6.2 runs, and it thinks it is on C: and
Windows-95 is on D:.</P>
