Checking the BIOS

A basic input/output system (BIOS) is a set of instructions stored on a ROM chip inside x 86 and compatible computers, which handles all input/output (I/O) functions.

Before upgrading to Windows 2000 Professional, check the BIOS on the portable or desktop computer to see that is has an updated BIOS. If the BIOS is not compatible, obtain an updated BIOS from the manufacturer.

If your system does not have Advanced Configuration and Power Interface (ACPI) functionality during installation, you might need to update the BIOS. However, to get ACPI functionality after Windows 2000 is installed, you are required to do another installation. You can, however, upgrade your existing installation.



Microsoft does not provide technical support for BIOS upgrades. Contact the manufacturer for BIOS upgrade instructions.
