BIOS Compatibility and Windows 2000
Posted: February 17, 2000
Finding out if your BIOS (basic input/output system) is compatible
with Windows? 2000 is important for two reasons:
You might not be able to use the advanced power management and device
configuration features in Windows 2000 if you do not have the most
current BIOS version for your system.
If your computer manufacturer has indicated that you need a new BIOS and
you do not update it, or you install the wrong BIOS version, your
computer may stop working properly. Please be aware that installing an
incorrect BIOS update may cause serious damage to your computer system.
Review the Question and Answer document below to find out more about
BIOS compatibility and Windows 2000.
Q: What is a BIOS?
The BIOS is the software interface that allows the Windows 2000
operating system to communicate with your computer's underlying
hardware. It is used to boot the computer when it is turned on. The BIOS
is the lowest level code that lives directly on the computer's main
circuit board (motherboard).
Q: Why do I need to update my BIOS?
Windows 2000 has advanced power management and Plug and Play features.
If you acquired your system before the manufacturer prepared it for some
of these new features, it may have a BIOS version that is not
compatible with Windows 2000. To work properly with Windows 2000, your
computer must have a compliant Advanced Configuration and Power
Interface (ACPI) BIOS, otherwise you won't be able to use the ACPI-based
power management support in Windows 2000. Updating your BIOS is
especially important if you have a notebook or laptop computer and you
want to take advantage of the latest power management features built
in to Windows 2000.
Q: What is ACPI?
ACPI stands for Advanced Configuration and Power Management Interface.
ACPI defines new working interfaces between Windows 2000, the BIOS,
and your system's hardware. These new interfaces include mechanisms that
allow Windows 2000 to control power management and device
configuration.
Q: What is power management?
Windows 2000 has power management capabilities that allow it to
control how much power a computer uses by putting it in lower power
"sleep states," such as Standby and Hibernate. Windows 2000 then "wakes"
the system up when you press the power button, and your system is fully
operational almost immediately.
Q: How do I know if my Windows 98 system requires a BIOS update?
Determine if your computer uses ACPI. You can tell whether your
Windows 98-based system uses ACPI by checking the list found in the
Device Manager.
NOTE: Windows 95 and Windows NT? systems do not support ACPI features.
From the Start menu, point to Settings, then Control Panel, and click
System.
Select the Hardware tab and then click Device Manager. If your
computer uses ACPI, Advanced Configuration and Power Interface appears
in the list.
NOTE: After you upgrade to Windows 2000, you can tell if you have ACPI
support if Standby appears in the Shutdown menu. If you get a BIOS
update from your computer manufacturer, you can enable ACPI-based
power management support after installing Windows 2000.
Q: How do I get the correct BIOS update for my computer?
You must know the make and complete model number of your computer. Check
your system documentation or contact the hardware manufacturer for
complete information. In some cases, you can determine the
manufacturer and model from the BIOS identification string that is shown
on the first screen when you turn your computer on (during the memory
count-up). When this screen comes up, push the PAUSE or BREAK button
to freeze the screen and note the long string of numbers and letters
at the bottom of the screen, excluding the date.
CAUTION! It is very important to obtain the correct version of BIOS for
your computer model from the manufacturer. Computer manufacturers may
offer several different BIOS versions. Do not download a version of BIOS
that is not specified for your specific computer model. Please be aware
that installing an incorrect BIOS update may cause serious damage to
your computer system. You are solely responsible for the accuracy of
your selection. Contact your computer manufacturer to ensure you have
the most current BIOS version.
Go to the Search for Compatible Computers area. This area lets you
search for computers that are compatible with Windows 2000. When you
search for your computer by model and manufacturer, some search
results include links to manufacturer Web sites that have the correct
version of BIOS for specific computer models. The search tool results
are not all-inclusive.
NOTE: The links provided from the Search for Compatible computers site
allow you to leave Microsoft’s site and access the computer
manufacturer’s site, from which you may download a BIOS update.
Microsoft does not control, and is not responsible for the contents of
any linked site, any link contained in such linked site, or any
