[ale] Quick question about HD and LILO

[Jim Kinney]

The drives are labeled as follows:
Ist primary=/dev/hda
any partitions are hda1, hda2, etc
the second drive on the primary is /dev/hdb
The first drive on the secondary is hdc
and the second on the secondary is hdd.

You will need a method to boot with a floppy. Toms rootboot disk 
comes to mind. Redhats rescue disk will also work well.

Boot with one of these and do the following:

mount /dev/hdb? /mnt/hdb?  /* the ? is the partition number*/
do this for the / and /etc and /sbin and /boot if they are on seperate
partitions. They are probably all just in / . I'll assume they are all in
the / partition (/dev/hda5 for example)

ln -s /mnt/hda5/boot /boot
ln -s /mnt/hda5/etc/lilo.conf /etc/lilo.conf
ln -s /mnt/hda5/sbin/lilo /sbin/lilo

This will make links that lilo will follow when run later.

In the file /etc/lilo.conf edit the lines that list your old 
/dev/hdc5 to be /dev/hdb5 

/* EXAMPLE*/

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz-2.2.5-15
        label=linux
        root=/dev/hdc1
        initrd=/boot/initrd-2.2.5-15.img
        read-only

/* BECOMES*/

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz-2.2.5-15
        label=linux
        root=/dev/hdb1
        initrd=/boot/initrd-2.2.5-15.img
        read-only

If you use the redhat rescue disk, it has pico for an editor (easy) the
other uses vi (not so easy)

now run:  /sbin/lilo

You should see that the lilo command adds a linux * line (in this case,
you may have other OS's installed). 

IMPORTANT!!!  cd /

umount /dev/hdb5

If you don't umount the drive, it may not get written to properly. now 3
finger salute, pop out the boot floppy and you should get you old LILO
prompt. If you have more than 1 OS in LILO, the tab key will give you a
list of keywords to boot with.
