4-4 Installing Your Rastergraf Graphics Board
JP1: VGA PCI Device Jumper
JP1 enables SM731 VGA BIOS to respond. If you are running in a PC
compatible machine and you want some other graphics board to run as
console, you may need to remove this jumper. This will prevent the
system BIOS from loading a VGA BIOS from the Rastergraf board.
Note:
The Rastergraf Windows 2K/XP driver does not usually work well in
concert with a different kind of graphics board. In other words, if you need
to have two graphics boards in the system, they both (or neither) have to
be Rastergraf boards.
If your CPU chip set has a built-in graphics adapter and you want to run
Windows, you have to disable it in the system BIOS prior to installing the
Rastergraf board.
JP2 and JP4: Alternate BIOS Image Jumpers 0 and 1
These jumpers are installed to select alternate BIOS images. At present,
these jumpers are not used.
JP3: Local 3.3V Regulator Enable
If the graphics board was built with the optional local 3.3V regulator
(VR1),
install
JP3 to enable the regulator to supply 3.3V power to the
graphics board when the PMC backplane only has 5V.
