Step 8 Connect the Mouse

The American Megatrends Enterprise-III EISA VL-Bus motherboard now has two types of PS-2-type mouse connectors:
• a standard 6-pin miniDIN plug, and
• a 10-pin berg connector.
You cannot use both mouse connectors simultaneously.
J100 is a 10-pin berg connector that attaches to a PS/2-compatible mouse via a standard serial cable. J3 is a six-pin
miniDIN socket (see below) labeled J3 on the motherboard. J3 accepts a PS/2-compatible mouse. The mouse
connnectors are next to the keyboard connector. Attach a customized serial cable from the mouse connector to a
DB9 serial port connector. You can order this cable from the American Megatrends Sales Department (404-263-

connector position is shown above. The J100 pinout and J100 itself are shown below. See the graphic above.
The DB9 connector pinout (on the other end of the cable) is:
