Boot Error

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

Have you tried booting to the CD-rom and seeing if that worked? Either it isn't getting enough power (doubt it) or you weren't properly grounded when replacing the motherboard. Perhaps clearing CMOS could help (it does wonders). And reconnecting cables is a good idear too
