I changed cases last week and after a few fits and starts got everything going again. There is one problem that I've found though - Windows XP (home edition) refuses to load APM. I looked in the system devices and there are no ACPI or APM devices loaded, even though I made no changes to the hardware. The only thing that's different in the hardware configuration is the power supply, which is a brand new model with full ACPI support.
This motherboard (Shuttle AK31 - Via KT266A chipset) ran fine w/r/t APM before the change, so I'm certain the problem is not in the motherboard or BIOS revision.
Things I've tried:
- toggled ACPI yes/no in the BIOS several times
- turned on/off BIOS ACPI features in various combinations
- forced an ECSD reload after each BIOS change
- reset BIOS altogether
- ran WindowsXP "repair"
None of the changes made any difference to XP - it refuses to recognize the motherboard as APM-compliant and so does not load APM. As a result, I get to deal with "It is now safe to turn off your computer" when I used to just walk away and let the OS shut down the supply. Annoying.
Anyone else seen this kind of thing? Any advice on how to resolve it?
Thanks,
Scott
