Miscellaneous | 80286 CMOS Battery and Setup

My first PC was a Philips P3204 AT 10 MHz Intel 80286, equipped with 2 MB RAM memory, a Hercules black and white graphics card (capable of 8 grey colors CGA), a 5,1/4 inch and a 3,1/2 inch disk drive, with a 20 MB Western Digital hard disk.

During the past few years I got regularly contacted with questions concerning the location of the CMOS battery, as well as instructions on how to access the computer's CMOS. This lead me to create this page that contains all necessary the details.


Below, you can find the instructions as scanned from the manual, both for the P3202 and P3204 models (click the images for a higher resolution).
