14 SOM-4450 User's Manual
3.1 Introduction
The SOM-4450 system BIOS and custom drivers are located in a 256
KB, 32-pin Flash ROM device, designated U17. A single Flash chip
holds the system BIOS and VGA BIOS. The display type 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 Utility CD disk
The SOM-4450 is supplied with a software utility on CD-ROM. This
disk contains the necessary file for setting up the VGA display.
Directories and files on the disk are as follows:
AWDFLASH.EXE
This program allows you to update the BIOS Flash ROM.
4450110.BIN
This binary file contains the system BIOS.
3.3 VGA display software configuration
The SOM-4450 on-board VGA/LCD interface supports an 18-bit TFT
LCD, flat panel displays and traditional analog CRT monitors. The
interface can drive CRT displays with resolutions up to 1024 x 768 in 24
bpp. It is also capable of driving color panel displays with resolutions
of 1024 x 768 in 18 bpp. The LCD type is configured completely via the
software utility, so you do not have to set any jumpers. Configure the
LCD type as follows:
AWDFLASH.EXE
4450Vxxx.BIN
