I downloaded the manual for the motherboard and nothing jumps out as causing the problem you have.
The only ones that might be of issue:
Ultra DMA - for the hard drive. Is this enabled (should be if you had device select set to AUTO)
USB Legacy Devices - Disabled or not
Video Memory USWC - is this set to UC (uncacheable) or USWC
Ethernet Lan Boot Rom - should be disabled
HOWEVER
Its mentioned in the bios revisions that there is a situation where XP can freeze on loading and this was fixed with Bios release 1.04. It was related to a setting in the bios that would cause the problem if set to disabled.
What revision of Bios are you running? A bios upgrade may be in order.
BTW Nice board.
