3.1Introduction
The PCM-3350 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.

AWDFLASH.EXE
CBROM.EXE
