creating a custom bootdisk

[markh@…]

Relevant file is BLFS/part2/chapter2a/bootdisk.xml

Basically this is so people can create a bookdisk for when they sod up their system by forgetting to run lilo or something

2 ways I know to do this, dd if={kernel image} of=/dev/fd0 or lilo -b /dev/fd0 Are we looking for linux on a floppy here, or just a boot disk?

Here it is, not sure which way we want to go here, I've used all of these successfully. Last one may be the most failsafe, as it uses a lilo.conf that already works, and just changes a few things.

Boot disk instructions

To make a boot disk with kernel on floppy - loads slower - better chance of booting failed system. Type dd if=vmlinuz of=/dev/fd0 <enter> Type rdev /dev/fd0 /dev/hdax<enter> note: where x is the "/" root partition number

To make a boot floppy with kernel on hard drive lilo -b /dev/fd0

get mkbootdisk script - better to work around 'customized' lfs systems

download ​http://rpmfind.net/linux/Kondara/Jirai/SOURCES/mkbootdisk-1.2.8.tar.gz su to root make

To create floppy type mkbootdisk --device=/dev/fd0 lfskernel

The way I've done it is as follows:

fdformat /dev/fd0H1440 mkfs.ext2 /dev/fd0 mount -t ext2 /dev/fd0 /mnt

cp -dp /boot/* /mnt

Copy /etc/lilo.conf /mnt/lilo.conf Change the boot=/dev/hda(or whichever device you have) to read boot=/dev/fd0

Make the floppy bootable with: /sbin/lilo -C /mnt/lilo.conf

umount /mnt

This needs actually putting into the book.
