Subject: How to make a bootable Linux floppy
Date: 30 Dec 1992 08:05:41 GMT

Here's a script I hacked to make a bootable floppy. It requires lilo 0.7,
as well as the new mount (0.97) and init (the one that will do singleuser
mode). Have fun, kids... :)

# This script makes a Linux boot floppy in $FLOPPY.

# This works on my system (Linux 0.99p1) - check to make sure that
# stuff is being snarfed from the correct place on your system.
# This script also requires that you have the latest mount (0.97) command,
# as well as an init that will boot to singleuser mode. It also requires
# that /usr/src/linux/Image exist.

FLOPPY=/dev/fd0
RFLOPPY=/dev/fd0H1440
# Set BLOCKS to be the number of blocks on $FLOPPY
BLOCKS=1440
# Set TZONE to be your timezone, AS DEFINED IN /usr/lib/zoneinfo!!
TZONE=UTC
