Building a Bootable Root Disk
Introduction
------------
You may wish to build a bootable root disk from your hard drive, to
use as a backup. These instructions should work for you:
1. Build and install LILO 0.9 on your hard drive. Read the docs
come with LILO 0.9.
2. I am using xia fs. Another choice is ext2 fs.
mkxfs -c /dev/fd0 [1200|1440]
3. mount -t xiafs /dev/fd0 /mnt
4. cp -av /etc /dev /mnt
5. cp zImage /mnt/vmlinux.z
6. copy libc.so.4.x in /lib to /mnt/lib
cd /mnt
mkdir lib proc mnt
cd lib
ln -s libc.so.4.x libc.so.4
We use cp to make some holes so that we can save some disk
spaces. Otherwise, there is no way we can put anything on a
floppy drive after kernel (300K) and shared library (700K).
6. copy what you want to /dev/fd0, which is mounted on /mnt in my
example, and make necessary directories. You need a few programs
in /bin, like sh, login, mkxfs/xfsck, mke2fs/e2fsck, .....
Please check my rootdisk for hints.
7. Do
cd /mnt/etc/lilo
rm -f map boot.????
./lilo -c -r /mnt -b /dev/fd0 -i /etc/lilo/boot.b -v -v -v /vmlinux
If you want to build a 5.25" bootable root disk or a 3.5" bootable
root disk in /dev/fd1, please contact me for details.
8. umount /dev/fd0
9. reboot
BTW, you can use my bootable rootdisk as a model for your own personal
rootdisk. You can delete/add whatever you want as long as they work for
me.
