Windows 2000 ACPI Problems

[Zedtom]

I installed Windows 2000, and now I have too many devices sharing IRQ 7. It seems to cause a problem when I boot up, because the display drivers are sharing the same IRQ as the on board audio, modem and USB drivers.

I tried to reinstall using the F6 key when the CD asks about raid/scsi drivers. Then you are supposed to push F7. It still installs with ACPI. I disabled PnP OS in the BIOS. I don't know what I'm doing wrong?

Is the system actually useable with ACPI enabled, with all devices working? With ACPI enabled, all of your devices will be on the same IRQ; that's how ACPI works. It assigns each device to the same IRQ, and then I believe it assigns virtual IRQ's to each device to avoid IRQ conflicts.

JW310 is correct. Win2k does put devices onto the same irq with acpi enabled.
This is normal and shouldn't disrupt the sytem from running properly.
However, if you want to bypass acpi on install, then you should press F5 at the beginning of setup (when press F6 shows up) and select Standard PC from the list.
You might have an option to disable acpi in your bios, and then you should also enable the pnp os option, and install normally.

You fail to mention what the problem is.

Thanks everyone for your help. The problem is that when I boot up, I get a display conflict when the OS starts to load. This only happens about one out of five times. I must reboot, and it straightens itself out.

This is an ECS K7SEM Micro ATX board with the newest BIOS flash. Yeah, I know... these boards have a bad reputation, but this is a hobby system, not my main machine. I've got a 350 Watt PS, so I don't think its a power issue. I have a GeForce4 MX440-SE 64MB card with the latest driver. The processor is an Athlon XP 1.4GHz. 512MB Memory.

I guess I'll just consider this problem to be part of the "personality" of the motherboard.

I will never buy an ECS board again! (oops, wrong forum!)

I finally got my display problem straightened out.

I had swapped out an ATI card for a NVidia card. I had removed all the drivers and uninstalled all ATI references. There was a service called, "ATI HotKey Poller" that was starting automatically. I disabled that- and now there is no conflict at startup.

Wise decision.
