error loading OS at boot

[m_ginty]

I'm tryng to install Redhat 9 onto an old system I've lying around.
It's got a scsi hd (not sure what size) and also a 20gb ide hd (on primary) inside.
I thought I had succesfully installed boot on reboot, I get a message saying "error loading OS".
I've booted from the cd agan and gone to linux rescue.
I did a chroot /mnt/sysimage (also did an /sbin/lilo initially but that didn't work) and my lilo.conf looks like this:
prompt
timeout=50
default=linux
boot=/dev/hdc
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear
image=/boot/vmlinuz-2.4.20-8
label=linux
initrd=/boot/initrd-2.4.20-8.img
read-only
append="root=label=/"

I can't remember how i set the partitions out as the install was sometime ago and I've only just gone back to it.
I've tried a stat command but no output so I've tried:
fdisk -l /dev/hdc
which gave this:
disk dev/hdc:20gb
255 heads 63 sectors/ tracks 2432 cylinders
dev boot start end blocks id system
hdc1 * 1 393 356741 83 linux
hdc2 394 1412 81851171 83 linux
hdc3 1413 2413 81851171 83 linux

I also tried the fdisk command with hda/ hdb but there was no output.
Any ideas as to the problem/ how to resolve or should I just start again?
thanks

It seems someone has put the IDE drive on the secondary bus. That might be the problem since most BIOSes only boot from the primary bus. Try moving the hard drive to the primary bus and see if that helps.
