I've just upgraded the BIOS and my machine is still saying that it is not ACPI compliant, what do I do?

The following applies to Win2k, ME, and XP.

This procedure explains how to disable ACPI if you can not resolve it in
the BIOS. In order to disable ACPI support with Windows 2000, you must
install a fresh copy of Windows 2000. This will erase the hard drive and
registry so you will have to re-install all of your programs. You must
make certain to backup all of your important data files.

1. Backup your important data files.

2. Boot with the Windows 2000/XP CDROM.

3. When it first starts the blue screen appears and you will see the
message at the bottom for about a second: "Press F6 to install a mass
storage controller". You will press F7 instead. After pressing F7 nothing
will happen but the system will be installed as a standard PC rather than
an Advanced Configuration and Power Interface PC.

4. Hit Enter to install a fresh copy.

5. You will press ESC to install a fresh copy of Windows 2000. From here
you need to delete and recreate the partition, and install Win2K into this
partition and follow the prompts.

6. The procedure takes about 30 minutes.
