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.
