General Mach Discussion / Re: Driver test failed: APIC seems to fail

It's working! the problem was indeed with the interrupt: the parallel port was set to use interrupt 7. it was set this way in the bios, and in the device manager the parallel port was set to use an interrupt. but, windows still didn't get it: on the resources page in device manager, there wasn't any interrupt mapped to the parallel port. so, I mapped IRQ7, et voila, the steppers are stepping!
the system is very stable now, the line almost completely flat. even 100KHz is no problem. one funny thing: APIC timing constant is still 0.
