A7N266-VM, windows XP, ACPI, install help

[Paul7]

I need help setting up a A7N266-VM with windows XP Pro.

This is my second one to setup and I had problems with the first one so now I have a few questions.
On the first computer under the device manager under computer it has "Standard PC".

1) Should it say "ACPI PC"?
2) Do I need to do anyhting special during the Windows install to make this say ACPI? I am booting from the CD and it starts the install right away after a few questions.

On the first PC, it will not shut down, it only goes to the it is OK to turn off pc now message. I read some post saying to go into power options in control panel and then go to APM tab and check some box. After I do that and then try to shut down, the PC will not shut down, it just reboots.

3) Where in the BIOS is anyhting asking "Pnp OS Y/N", I can't find it, does it matter?
4) Is there anyhting in the BIOS for ACPI to be set on or off...?

From what I have read, for the first PC, the only way to get the PC to say "ACPI PC" is to reinstall windows.

5) Is this the only way?
6) What will be lost if I reinstall, will the registry and all be redone and what about all the software that has been installed?
7) Do I do a reinstall or repair?

Thanks for any help or links in response to this.

I have XP pro on my A7N266-VM as well and it does say ACPI uniprocessor PC, BTW I didn't do anything special during the install it was gravy. I don't see a APM tab in my power management options, I just have it set to home/office desk and chose 20min for the monitor and never for the shut down option on the HDD and standby. In the bios I left the power management alone except to make sure ac power loss recovery was on. You should make sure that in the boot menu the interrupt mode is set to APIC. BTW I didn't know XP pro would give you the "it's OK to turn off PC now" message. As to what is necessary to make XP id as a ACPI uniprocessor PC I'm not certain, Although you may want to update to the latest bios then if necessary do the re-install with the bios settings at defaults and see if all goes well as I even tweaked the bios and had no issues like you are describing.
