Error on Boot - never happened to me before

[Battery Powered]

Hello

ive been using the same system for over a year, redhat 7.3 and had no problems
Until recently i needed to change PSU and case, so i did the change yesturday and when i turn on i get this :

Mounting root filesystem
ide-floppy driver 0.99.newide
kmod: failed to exec /sbin/modprobe -s -k ide-cd, errno 2
hda: driver not present
mount: error 6 mounting ext3
pivotroot: pivot_root(/sysroot,/sysroot/initrd) failed 2
freeing unused kernel memory: 312k freed
Kernel panic: No init found. Try passing init = option to kernel


then i wait a minute or two and one more line apears:

Spurious 8259A interrupt: IRQ7


Does anyone know what im suppose to do here, the bios detects the harddrive and cd so the cables all have to be ok - im not sure what else i can do
Would really appreciate some ideas
All the best everyone,
B.P

If I understand correctly, all you did was install your motherboard and all your hardware in a new case with a new PSU. Given the error, you would have to suspect that when you did so the ide configuration changed. It's looking for something on hda(primary master) and can't find it, thus the kernel panic. I'd double check to make sure your hard drive is IDE1, master. Check it in your BIOS. The hard drive should be listed as primary master. If not, reconfigure your hardware so it is.

it could be that your file is pointing root to the wrong partition. check your lilo.conf or grub.conf

How can I check these config files if I cannot get the system to finish booting?

If i explain the problem I had a little more, the PSU blew on me, and needed replacing
and by blew i literally mean that - dont ask me how as i will hang my head in shame..

could this of effected anything?

The PSU blowing could have effected a lot of things. If you were booted in RH at the time, I think you could expect some file system corruption. I assume you're using ext3 which is RH's default. As for accessing the partition, I beleive Rh install CD1 has a rescue mode which will allow you to do this from a command line. If your more comfortable in a graphical enviroment, have broadband and a CD burner, try downloading the knoppix iso from here:

Knoppix is a linux distro that runs entirely from a bootable CD. You boot into kde and have full access to all your partitions.
