Hardware and performance

A while ago, I intended to migrate a moodle server from a linux machine(A) to another linux machine(B), so I take two HDD out, 36 GB and 140 GB HDD which consist of, operating system and moodle(user, course) data respectively.

Problem occurred after I put these two hard disk on B machine, which is, it failed to load up although those HDD are detected smoothly, the screen display the message as below:

Uncompressing Linux... OK, booting the kernel
.. MP-BIOS bug: 8254 timer not connected to IO - APIC

Red Hat hash version 5.1.19.0.3 starting
Reading all physical volumes. This may take a while...
No volume groups found
Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: Could not find file system '/dev/root/'
setuproot: moving /dev/ failed: no such item or directory
setuproot: error mounting /proc: no such item or directory
setuproot: error mounting /sys: no such item or directory
switchroot: mount failed: no such item or directory
kernel panic - not syncing: Attempted to kill init!

I think it is maybe caused by incompatible SCSI code.

Please advise above matters.

Thank you.
