Chapter 3 Software Configuration

3.1 Introduction

The system BIOS and custom drivers are located in a 512 KB, 32-pin

(JEDEC spec.) Flash ROM device, designated U15. 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 onboard VGA interface supports a wide range of popular LCD, EL,

gas plasma flat panel displays and traditional analog CRT monitors. The

855GME chip with optimized Shared Memory Architecture, supports up

to 32 MB frame buffer using system memory to provide LVDS mode up

to UXGA panel resolution with frequency range from 25 MHz to 112

MHz, the interface can drive CRT displays with resolutions up to 2048 x

1536 @ 75 Hz.

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.
