ACPI in Win2K disabling it, please help

[Exiler]

Can anyone please tell me how I can disable ACPI in Win2K before installation?

I have a ASUS CUSL2-C Motherboard, and I dont know how to disable the ACPI, the only option I see is disable the PnP OS and thats it.

I tried disabling the PnP OS in BIOS and installed Win2K and now all IRQ are set at IRQ 9, which effects my internet since my Network card and video card and everything else uses it.

Also after installation, I read from the past post, that in order to
disable the shared IRQ, you just have to change the ACPI driver,
well I dont see what I can change it to.


In System Devices there is:

ACPI Fixed Feature Button
and
Microsoft ACPI-Compliant System which takes IRQ 9


Which one do I change and EXACLTY to what, cause I dont know what
to choose.


I can re-install Win2K again if I have to, so please tell me what to do. I did 2 times reinstallation and the PnP OS in the BIOS had zero effect.

And there is NO ACPI option in the BIOS.

If you have no option to turn it off in the BIOS then you'll have to go into Device Manager, click on Computer, and change the ACPI Compliant PC driver to Standard PC. Reboot. When you restart Win2K will probably redetect and reinstall your devices.

You can do this at the beginning of installing Win2K by tapping F5 right when the blue installation screen comes up (is also where it tells you to press F6 for SCSI controllers).

Hope it gets straightened out.

i updated mine once to standard pc to be just sure wasnt losing performance on anything (video card mainly) and actually my bench scores were worse. that made me think there is no problem using ACPI with a full compatible system but: if i disable ACPI during setup can the results be different than updating it for standard pc after installation?
thanks.

I've seen a few posts detailing the disabling of ACPI in Win2K. Why is this being done, stability, performance?

dunno why other people do it, but i turn off mine because it sets ALL my pci/agp devices to the same irq.

video card, net card, scsi card, sound card, raid controller (on board)

i think that's all of them, i'm not at my home computer now.

anyhow, i would tend to get lockups on heavy disk activity (hard drive, on the ide raid controller) and would have to actually flip the power off on the PSU or hold the power button in for 14 seconds. ctrl+alt+del does nothing, reset wont work, etc.

once i went to standard pc, all my problems went away (as well as each of my devices getting their own irq). i am assuming it was the irq thing, but honestly i cant say for sure. abit manual says to not let the raid controller share irq with anything. w/ acpi enabled, this is not possible to change irq's.
