Updating the ThinkPad system BIOS for Windows Me
Before you install or upgrade your system to Windows Me, you
must update the BIOS (basic
input/output system) of your ThinkPad computer.
To take full advantage of all the features
offered by Windows Me, it is strongly recommended that you update your ThinkPad’s system
BIOS. If you do not update the system BIOS before installing Windows Me, you will encounter
problems with the Setup utility and Windows Me will not operate properly on computers with an
outdated BIOS.
Below is a list of BIOS versions that needs to be updated prior to clean or upgrade install. The
latest Flash BIOS Update Diskette (System Program Service Diskette) file and installation guide
can be obtained from the IBM ThinkPad support Web site:

Note that the BIOS versions listed in the following list may not be the latest as IBM keeps
updating the BIOS. Please make sure to download and update to the latest BIOS available on the
web.
