Chapter 3 Software Configuration
3.1 Introduction
The SOM-4486 system BIOS and custom drivers are located in a 512 KB,
32-pin Flash ROM. 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-4486 is supplied with a software utility on CDROM. 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.
4481Vxxx
This binary file contains the system BIOS.
3.3 VGA display software configuration
The SOM-4486 on-board VGA/LCD interface supports an 18bit TFT
LCD, flat panel displays and traditional analog CRT monitors. The inter-
face can drive CRT displays with resolutions up to 1280 x 1024@32 bpp.
It is also capable of driving color panel displays with resolutions of 1280
x 1024 @ 16bpp. The LCD type is configured completely via the soft-
ware utility, so you do not have to set any jumpers. Configure the LCD
type as follows:
