I am attempting to upgrade from Windows XP Pro SP2 to Windows Vista Home
Premimum. When I incert the CD, Vista comes up with the message that my
computer is not ACPI compliant. I checked my bios settings, APCI is enabled,
so I assume for some reason it was not installed when I installed XP. I
checked the device manager and it was not. However, I attempted to reinstall
XP and I cannot for the life of me get ACPI to install. I tried pressing F5
during the raid driver installation and nothing happens.
How do I get my computer to install ACPI?
My motherboard is an NF550 Biostar Tforce 550. It's Windows Vista Certified
and APCI compliant.
