Re: Bios is not ACPI compliant...?
Try removing all add on cards, modem. nic, etc.
Also, if you want to do a bios update, you will need to find the latest bios for your board by checking the manufacturers website. Typically this means making a startup disk, and putting the flash utility, and the bios rom, or bin file on a floppy. Boot to floppy, run the flash util., and replace your bios with the newer one.
