Ok so you are watching for the IRQ ack from the IRQ driver. I don't
know a whole lot about the deep internals of the windows irq stack.
Does the system ACK the IRQ and pass up up a notification or when you
hook the IRQ is your driver responsible for all that.
By driver I meant the chipset driver so they can't be the same. Via
vs nvidia. I would guess that the difference is in the way the
chipset driver deals with interrupts.
Unless you can somehow track it down to a setting in the chipset I
doubt linuxbios will be much help.
Are you using some type of RTOS extensions for XP? I wasn't aware
that you could get response times that small with XP.
