I can't boot from Installation CD of FreeBSD-6.0. 
When I am booting from CD-ROM, I see a looped message similar to this:

int=0000000d err=00000000    efl=00010046 eip=000090db
eax=00000011 ebx=00000700    ecx=00000000 edx=00000000

       72 72 3d 30 30 30 30 30-30 30 30 20 20 65 66 6c
BTX halted

My system is:
1. SCSI Host Adapter DC-390 Series 
2. Motherboard Gigabyte GA-6OXT

Note: I can boot from Installation CD of FreeBSD-4.10 without any problems.
