Chapter 1. Introduction
The WAFER-5823 is a CPU board equipped with two ethernet
controllers so it is a special design most appropriate for
Network applications. It supports the full functions of an
AT-compatible industrial computer on a single board. The
WAFER-5823 is also equipped with a low-power consumption
and high performance GX1 processor on board moreover
contains an SDRAM SODIMM socket that can support up to
512MB memory.
The WAFER-5823 aside from providing two Ethernet interfaces,
it also has FDD interface, EIDE interface, Compact Flash Type II,
one parallel port, two serial ports RS232, two USB ports, and a
6-pin header PS/2 keyboard/mouse interface. The built-in
SVGA/LCD display controller supports both CRT and LCD display
simultaneously. It offers the resolutions of LCD screen up to
1024 x 768 and CRT resolutions up to 1280 x 1024 @ 256
colors. The Flash ROM contains both the system BIOS and the
VGA BIOS. If necessary, reprogramming the Flash ROM could
do the modification to fit actual need.
