VIDEO CONFIGURATION

The COMPAQ Video Graphics Controller Board (Assy No. 109360) has two jumpers, J1 and J2, that must be set to allow the board to work properly with your computer system.  Refer to Figure 8-7 for illustration of the board.

Jumper J1 configures Video RAM for 8 or 16 bit operation.  Jumper J2 configures BIOS ROM for 8 or 16 bit operation.  The recommended settings are:

J1 = 16 bit operation

J2 = 8 bit operation
