Just completed a system upgrade using Intel D945GNT MB, D820 Processor. BIOS is by Insyde and have flashed the latest available update from Intel site. System has two bootable drives, both with Win XP Home, one is IDE, other is SATA. Both XP systems run just fine with no problems whatever. However, if I select "Restart" from the "Turn of your computer" menu, the system will not restart and apparently hangs in the BIOS. Win XP shuts down OK, but after a few seconds the BIOS splash screen appears (just like on a normal boot). In the lower right hand corner I see "BIOS Settings <F2> 58". During successful boot, the 58 changes as the BIOS progresses and then Win starts. During these unsuccessful restarts, the splash screen hangs there forever and F2 will not get you into BIOS setup. It's as if it were waiting for something - maybe hard drive? - that is never going to happen. If I then power off and on, the system boots up correctly. This happens every time I try to restart. I've tried different value for HD Pre Delay in the BIOS, with no effect. Anyone have an idea on how to proceed?
