Hi I'm having problems with an ABIT KV7 mobo. Spec: ABIT KV7 2 x 512MB DDR400 RAM 1 x 120GB Maxtor S-ATA HDD 1 x Radeon 9800PRO I am attempting to install Windows XP home onto the S-ATA drive, I am able to install the additional driver using F6 during text setup and then it continues to load generic driver files. When it attempts to start the windows installation i get a blue screen error telling me that "my mobo BIOS doesn't support ACPI" i know for sure that it does and followed the advice given (F6 and manually select ACPI) but still no go. Any suggestions? Regards Gary

I think I heard that ACPI needs to be set prior to the installation of XP. Before you got re-installing I would try to verify that because I don't know for a fact that's true.

Once you drop the CD in the tray and fire up the computer to install XP, the first thing you'll see at the bottom of the screen is the option to press F6 if you need to install a SCSI or RAID controller. Don't press F6. Press F5 instead. This will take you to a separate menu of Hardware Abstraction Layer's where you can choose an appropriate HAL that supports ACPI. The choices will be: ACPI Multiprocessor PC ACPI Uniprocessor PC Advanced Configuration and Power Interface (ACPI) PC Compaq SystemPro Multiprocessor or 100% Compatible PC MPS Uniprocessor PC MPS Multiprocessor PC Standard PC Standard PC with C-Step i486 Other In the majority of installations the 'Advanced Configuration and Power Interface (ACPI) PC' HAL is the one you will want to use. A few cautions are also in order: Obtain and install the latest BIOS for your motherboard before you begin the XP installation. Make sure ACPI is enabled in bios Unfortunately, XP doesn't always recognize a computer BIOS is ACPI capable and doesn't install the support for ACPI.

Hey, my notebook doesn't support changing fan speed (under winXP). There is a little dos-tool that can do it but I can't see a chance to do it under xp. Might that be because of the missing ACPI support?? How can I see what ACPI (HAL) is supported on my system? Is there a opportunity to install it on the running system? Thank's for your help!! Joe
