If you think your BIOS's ACPI will work, you can add this to your boot command: acpi=force Of course if it doesn't work then take that back off. > Why are this BIOSes blacklisted ? I agree with Zwane Mwaikambo's answer as to why, but I think that 1999 is likely to be safe. 1998 was dodgy. By the way, since Mr. Mwaikambo spoke of Monopolysoft systems, I'll add a bit. Windows 98 can be switched between ACPI and APM after installing, though it probably requires multiple reboots (one reboot to load one of the newly selected drivers and additional reboots to load drivers for redetected devices further down the chain). For Windows 2000 and XP you can force a selection at the beginning of installing, using a poorly documented technique, but they cannot be switched afterwards. For Windows 2000 and XP, if the installer doesn't get forced, it checks lists of known good BIOSes and known bad BIOSes, and then goes by date for BIOSes that aren't on either list. But I think they default to assuming 1999 was good, since Windows 2000 was essentially completed in 1999.
