Hello Praveen,

well so far I didn't manage to boot anything.  Of course the OS cdrom is 
nowhere to be found  (I am trying to locate the disk for Linux 
2.6.12-1.1381_FC3smp  (I know, old, but it is one of those machines with 
"if it ain't broken don't fix it)

What happened is:

The machine acted 'weird'  the whole file system seemed to be read only. 
(I didn't log in to it for a while)

I rebooted the machine and got to see the  raid battery/memory error. 
The machine booted fine. I looked up the error on the web and it said 
that there was either a faulty battery or faulty raid memory.

The machine seemed to be working fine so I ordered a new battery.
Than the same problem occurred; I rebooted and that is when I saw the 
kernel panic.

So I ordered a new raid kit.  machine boots fine now, no hardware/bios 
errors   but I still have the kernel panic
