My BH6 1.01 works fine under Win2k, even better with ACPI disabled. ACPI caused some flakyness with my BH6, but it works beautifully without ACPI. In case you don't know how to disable ACPI, you must do it when installing Win2k, I've heard of major problems with switching to Standard HAL after installation. When the screen pops up that says 'Press F6 to install third party SCSI or RAID drivers', press F5 and select Standard PC & hit enter, *or* you can do the silent switch by pressing F7 when the F6 screen is there. Good luck
