Lost initrds

Ive searched various archives and done Google searches with no answer to my
problem.

I have an SMP RH7.0 which I upgraded the kernel from 2.2.16 to 2.2.19.
Unfortunately, the upgrade process did not build initrd images for the
new kernel. Rebooting I realized the system wasn't booting because of
the missing initrd images (The disks are SCSI so Im assuming the initrd's
preloaded SCSI drivers so my kernel can see /dev/sda1).

The worst part is that the old kernel is also gone so I cannot boot back to
the old state to run mkinitrd!

Does anyone have any ideas? I really want to keep the disk intact.
I don't have a boot disk tailored for this system.

All I need is a boot disk image with SCSI drivers where I can boot and tell it
where the root device is (thereby removing the need for the initrd).

Or if I can find /boot/initrd-2.2.19-7.0.16smp.img and somehow get LILO to
run and write to the boot sector on /dev/sda1 instead of the rescue disk
But how?

All I can do right now is boot off the RH7.0 boot floppy or CDROM and invoke
rescue mode. (Rescue mode appears to have very little tools available to help).

Any ideas would be greatly appreciated!

Thanks.
