Chapter 3 Software Configuration
3.1 Introduction
The system BIOS and custom drivers are located in a 256 KB, 32-pin
(JEDEC spec.) Flash ROM device, designated U10. A single Flash chip
holds the system BIOS, VGA BIOS, and network Boot ROM image. The
display can be configured via software. This method minimizes the num-
ber of chips and eases configuration. You can change the display BIOS
simply by reprogramming the Flash chip.
3.2 VGA display firmware configuration
The board’s on-board VGA interface supports a wide range of popular
LCD, EL, gas plasma flat panel displays and traditional analog CRT mon-
itors. The optimized shared memory architecture supports an 8/16/32 MB
frame buffer using system memory to provide resolutions of 1280 x 1024
@ 16 bpp, the interface can drive CRT displays with resolutions up to
1024 x 768 @ 16 bpp and 800 x 600 @ 16 bpp.
The VGA interface is configured completely via the software utility, so
you do not have to set any jumpers. Configure the VGA display as fol-
lows:
1. Apply power to the board with a color TFT display attached. This
is the default setting for this board. Ensure that the AWD-
FLASH.EXE and *.BIN files are located in the working drive.
NOTE: Ensure that you do not run AWDFLASH.EXE
while your system is operating in EMM386
mode.
