Good morning Hicookie:
It looks like the BIOS is chocking on ACPI service which I believe is the south bridge interface. You may want to disable all the hardware in the BIOS to reduce PCI conflicts and try turning PLUG and PLAY OS On or Off to see if ACPI gets assigned another IRQ or PCI buss #.
From what I see, all these AOPEN boards seem to be real crap.
EDIT: What south bridge is used?
