FreeBSD 6.x won't install or run on my Ampro Mightyboard 800.  
Installing from Known good CD's with versions 6.0. 6.1 and 6.2Rc1 all 
generate the following error after present [Enter] at the menu prompt.

This board has an Intel Celeron Processor, 512Mb RAM, a Seagate HD and a 
Sony CDROM. It uses a BIOS from General Software dated 5/11/05.  ACPI 
and APM have been disabled at the BIOS level.  The same configuration 
successfully loads, installs and runs NetBSD 3.1, CentOS 4.4 and WindowsXP.

Connecting a working Freebsd 6.1 disk generates a 'Fatal trap 9'.

Start screen output
............
Fatal trap 9: general protection fault while in kernel mode

trap number            = 9
panic: general protection fault
Uptime: 1s
Automatic reboot in 15 seconds - press a key on the console to abort

I'm stumped and looking for suggestions.
