BTX Halted from 5.2.1 CD, MS-9211 1U Rackmount Server

[j snod]

As soon as my machine boots off the CD, I get a memory dump of some sort 
followed by "BTX Halted" ...

BTX Halted

Sometimes this BTX Halt only happens once and hangs the system, other 
times it dumps this info to my screen over and over in an infinite loop. 
  Only a power down stops it.

I've come across TONS of articles/discussions with the same problem but 
none of their suggestions have worked.  I've verified that I have the 
latest BIOS for my motherboard, but it does not have a "Virtual boot 
device" to disable.  I forced my IDEs to use PIO as suggested in one 
discussion, no worky.  I've disabled all unneeded items in the BIOS, 
including unused IDE channels, USB, onboard LAN, still no fix.  I've 
verified that my RAID drivers work with 5.2.1 as seen in other 
dicussions.  I've verified the MD5 of this 5.2.1 disk before burning, 
and I've also used this very CD to install on another machine with no 
problems.

The 5.1 and 4.10 CDs boot just fine.

My system:
MSI P1-1000 1U Rackmount
http://www.msi.com.tw/program/products/server/svr/pro_svr_detail.php?UID=376
Motherboard says: "MS-9129 Ver 1"
BIOS Version: W9211MS v1.0 121002 19:07:50
RAID BIOS: MB FastTrack "Lite" 2.00.1030.27

IDE1 Slave : NONE
IDE2 Master: CD-ROM (Mitsumi SR244W1)
IDE2 Slave : NONE

Please Help!  Any ideas?

Thanks,
