Vista, ACPI and upgrade failure

[kwinsw]

Hi,

I wonder if anyone can help me. I recently bought Vista, having used the upgrade adviser to check that my PC was Vista-ready (it told me that it was). Now, however, when I try to install I get an error message telling me that my motherboard (K8N Neo4-F PCB 1.0) is not ACPI compliant, that Vista won't install and that I need to update my BIOS or buy a new motherboard.

I have updated the BIOS, but Vista still won't install. The Power Options entry in Windows Control Panel only has a tab for APM, not ACPI. In the BIOS settings the only reference I can find to ACPI is what ACPI standby state to use - [S1 (POS)] or [S3 (STR)] - nothing about how to enable ACPI. The manual makes no mention of how to turn on ACPI either, just these two states.

So, my question: is this board really non-ACPI compliant (I only bought the PC in 2005) or does anyone know of some way to turn ACPI on in the BIOS?

Any and all help much appreciated.

Thanks

In case anyone is interested, the board does appear to support ACPI. For some reason, however, the ACPI component of Windows XP was not installed. I ran the XP install again, the install routine found the previous XP installation and repaired it.

As a result, the Vista install (upgrade run from within Windows; it must simply have been looking at Power options in the Control Panel) now no longer fails because it can't find ACPI support. It fails for an entirely different reason (you have to smile). Think I can sort this one out, though.
