Oops. I missed that the scsi.s image no longer exists in 13.0. My bad.
Well, if you can boot with the install CD and see all of your drives then it's almost easy to generate an initrd.
First thing is to mount your installation root partition on /mnt. Then you should be able to look at /mnt/etc/fstab to mount the other partitions accordingly. Then run
, which will then allow you to run the mkinitrd command (it will be able to find the kernel modules and binaries that you installed). Make sure to specify the kernel that you want via the "-k" flag as well as checking lilo.conf prior to re-running lilo. (I've converted to grub, myself, so I won't be of much help with lilo.)
Then give the "exit" command to get out of the chroot and reboot. Hopefully, things will work now.
