Chapter 3 Software Configuration

3.1 Introduction

The PCM-3370 system BIOS and custom drivers are located in a

256 KB, 32-pin (JEDEC spec.) Flash ROM device, designated U23. 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 number of chips and eases configuration. You can change the display BIOS simply by reprogramming the Flash chip.

3.2 VGA display firmware configuration

The PCM-3370’s on-board VGA interface supports a wide range of popu- lar LCD, EL, gas plasma flat panel displays and traditional analog CRT monitors. 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 PCM-3370 with a color TFT display attached. This is the default setting for the PCM-3370. 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.
