PocketLinuxers:

Many distributions use GRUB as the bootloader program instead of LILO,
even though GNU hasn't officially released GRUB. Thus, an 
alternative/optional Chapter 2 of the Pocket Linux Guide using GRUB is appropriate. The required 
series of commands are listed below, assuming a floppy disk in /dev/fd0 and 
that GRUB is the bootloader on the host Linux OS.

bash# mke2fs -m0 /dev/fd0

bash# mount /dev/fd0 /mnt

bash# mkdir /mnt/boot

Comment: build the appropriate kernel

bash# cp /boot/vmlinuz /mnt/boot/vmlinuz

bash# mkdir /mnt/boot/grub

bash# cp /boot/grub/stage1 /mnt/boot/grub/stage1

bash# cp /boot/grub/stage2 /mnt/boot/grub/stage2

bash# cp /boot/grub/e2fs_stage1_5  /mnt/boot/grub/e2fs_stage1_5

bash# grub-install --root-directory=/mnt '(fd0)'

Comment: grub-install will ask if the device mapping is correct. If the line
(fd0) /dev/fd0 is present, all is well for our purposes.

bash# cd /mnt/boot/grub

Comment: Create the file menu.lst using your favorite editor. menu.lst is the
GRUB configuration file. Ours will be very simple.
