Error message on any softmenu tweaking on IC7

Whenever I do any tweaking in the softmenu menu in the bios, The system starts to boot up normally, but then it looks for a boot disk, and wont boot from hard disk. Anyone have any experience with this?

System is:
IC7 mobo
2.8c p4
aeroflow cpu cooler
saphire 9600
wd 74 raptor

Make sure the AGP/PCI is set to "fix" and "66/33".
