Bits 12-15 are reserved according to the BKDG I have. Maybe you should try printing those values earlier? I don't know what's going on to get such strange values. So the default link is 0, and the Routing Table Disable bit is set to zero. You mentioned bit 11 - that seems to be marked as 'reserved' in the BKDG for fam10? In the version I have it's marked as read only. Thanks, Myles -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
