problem changing SCSI cards on RedHat 6.2

It's in the ramdisk that's being loaded during boot. Look at the initrd
parameter in your lilo.conf file for the exact pathname. For now I'll use
the pathname on my RH 6.1 system to illustrate.

+ your system unbootable in a heartbeat.  The trick is to always have a +
+ fallback plan, i.e. boot disk, boot entries in lilo.conf, etc.        +

First uncompress the image:

zcat < /boot/initrd-2.2.12-20.img > /tmp/initrd

Next mount the ramdisk:

mount -o loop /tmp/initrd /mnt

There is a script '/mnt/linuxrc', which should be loading your
modules at boot time. The modules are in /mnt/lib. Add/remove files and
edit linuxrc to reflect the changes you want to make...

Next unmount and recompress the ramdisk image. Don't forget to save a
backup of the original ramdisk. I'd create another entry in lilo.conf in
case you need to boot off of the original ramdisk.

umount /mnt
gzip < /tmp/initrd > /boot/initrd-2.2.12-20.img

Last thing is to do a lilo so it can do it's mapping thing.
