The computer is an Compaq Proliant DL360 1U-Rack server
The cdrom is connected to an IDE controller as /dev/hdc

Yes it has a Compaq SMART2 Raid controller, but both drives
have been disconnected so that they don't interfere with booting.
(If connected, it loads kernel from cdrom, then loads root from HDD)

This CDROM is supposed to be able to be inserted into a fresh
server with no partitions on the HDD's. When booted, it will detect
the HDD, partition it and then install some rpm packages to get a
basic setup running.

I have also tested this cdrom in a few other computers with the
same error messages.

"enableapic"? I just assumed it existed.
