How to use this guide
This manual is written to help you use Peak 555A. The manual describes how
to arrange various settings on the Pentium CPU board to meet your
requirements. It‘s briefed as follows:
Chapter 1, “Introduction” gives an overview of the product‘s specifications.
It also tells you what are included in the product package.
Chapter 2, “Jumpers and Connectors” describes the definitions and positions
of Jumpers and Connectors that you may easily configure and set up per your
requirement.
Chapter 3, “Capability Expanding” describes how to change or expand the
CPU Board by changing the system memory, cache memory, and CPU to get
more power out from the CPU board.
Chapter 4, “Award BIOS Setup” describes how to use the advanced
PCI/Green BIOS to control almost every feature of the Peak 555A, including
the watchdog timer.
The Appendix describes how to set up the Watch Dog Timer (WDT) and
gives an example to program the WDT.

Introduction
Welcome to the PEAK-555A Pentium single board computer.
The PEAK 555A is a brand new generation of advanced technologies.
They are built with high performance socket7 CPU with clocks up to
100MHz, high performance PCI Bus and I/O's, and the brand new
technologies: the pipeline burst cache and the 4th generation VGA with
Unified Memory Architecture (UMA) are also included. An optional
ultra wide SCSI module also gives the PEAK 555A unique feature. It's
excellent to the system integrators, VARs, or turnkey vendor demanding
high performance computing, high performance I/O and the best
solution as the Industrial workstation, and the controller in the computer
telephony application.
The PEAK 555A can run with Intel Pentium MMX processor up to 233
MHz, the brand new socket7 CPU like AMD K6-2 with 100MHz external
clocks are also supported. The CPU support up to 400MHz very high
performance, moreover, think to its advanced design, the Peak 555A
also supports Intel low power CPU up to 266 MHz. It could run without
and cooling fan! Memory support up to 512 KB/1MB pipeline burst
cache and 512 MB SDRAM. This generates great computing power.
The Winbond integrates the floppy controller, two serial ports, one
parallel ports as well as the KBD/mouse controller. The two on-chip
UARTs are compatible with NS 16C550, and the parallel port support
EPP/ECP. The on board VGA is a high performance graphic and
video accelerator and 3D AGP built in, with the unified memory
architecture it can fully utilize the system memory up to 1280x1024, true
color, and 1600x1200, high color . The shared memory could be 8MB
for display purposes. The IDE now supports the Ultra DMA/33,
DMA/66 and the USB ports are also reserved, the socket for Disk on
Chip of the M-systems is on board, supporting up to 144MB. The 10
Base T/100 Base TX Ethernet Controller is standard on board with PCI
Interface. The proprietary PCI Bus is reserved. Now it’s for the

adapted AIC 7880, the Ultra wide SCSI module. It’s easy to design
another module if necessary.

Specifications 1-3
The additional keyboard connector is reserved for connecting to the
keyboard connector on the back plane. The high precision real time
clock/calendar is built in for accurate scheduling and the watchdog timer
is also the standard feature.
A special circuit is reserved to monitor the CPU cooling fan. If the
cooling fan stops or abnormally slow, the buzzer will beep as alarm.
The Peak’s unique offering the ISAMAX is the standard feature of the
Peak 555A, and supporting up to 20 PCs of ISA add-on cards without
any problems
A 4pin power connector is severed on the advanced power regular
module for standalone application. The Peak 555A already integrates
lot of features on hand. It’s actually complete enough for most of the
normal applications.
The PEAK 555A will be available our two module as follows:
--- PEAK 555VL: All common feature plus V6A and LAN, no SCSI
module.
--- PEAK 555A: Plus ultra wide SCSI module.
