I have been through my BIOS but cant really figure this out.

I am using a DSATX, Windows XP SP2, and a Foxconn MB.

I can enter standby or hibernate fine (I shut off ignition and DSATX sends signal to jumper power button pins on the MB)

When I turn the ignition back on the MB wont come out of hibernate or standby by the power buttin pins being jumped. Sometimes a PS2 keyboard will work but even that’s not every time.

Has anyone heard of a MB that wont allow resume from the power button being pressed?
