PEGASUS

1.0 Introduction

Pegasus is a highly integrated and self-contained Single Board Computer (SBC). Using a Socket
370 with the Intel 810 chip set, the Pegasus board will accept a full range of Intel Celeron and
Pentium III CPU’s up to 800 MHz. Pegasus’ performance is unmatched in its class with these
powerful yet cost effective Intel processors and a 168 pin DIMM slot for extra large memory
capacity.

On board features include two serial, one parallel, two USB and one 12 bit digital programmable I/
O ports. The on board PCI IDE interface supports one IDE device up to UDMA-66 and the
PCIMG expansion bus can support multiple devices with automatic Front Side Bus switching.
Also included are a floppy disk controller, high speed timer (1 us resolution), built in PS/2
keyboard and mouse ports, AC’97 audio, VGA and a 10/100 Base-T Ethernet port.

Flexstar also offers a wide array of options and accessories for the Pegasus. Ultra DMA 100/133,
Fibre Channel and various SCSI host bus adapters are available; along with programmable DC
voltage controllers with built in current and voltage monitor/capture functions. FlexStar also offers
a diskless remote boot software package for the ultimate in self contained and ruggedized
operation. Please visit FlexStar’s web site at www.flexstar.com for more details.

The Pegasus uses a CR2032 battery, which is used to maintain the
CMOS when the unit is powered off. The battery has a life of
approximately 10,000 hours. How many months the battery is good
for depends on how many hours the unit is ON or OFF.)

2.0 Installation

This chapter explains how to set up the Pegasus hardware, including instructions on setting
jumpers and connecting peripherals, switches and indicators. Be sure to read all the safety
precautions before you begin the installation procedure.

Always disconnect the power cord from Pegasus when you are working on it.
Do not make connections while the power is on as sensitive electronic
components can be damaged by the sudden rush of power. Only experienced
electronics personnel should install and/or maintain Pegasus.

Always ground yourself to remove any static charge before touching the PC
board. Modern electronic devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all electronic components on a
static-dissipative surface or in a static-shielded bag when they are not in the
chassis.

2.1 CPU Installation & Upgrade

The Pegasus provides a Zero Insertion Force (ZIF) socket (socket 370 type) for easy CPU
installation.

1. Make sure the ZIF socket lever is in the upright position. To raise the lever, pull it out to
the side a little and raise it as far as it will go.

2. Place the CPU in the empty socket. Follow the instructions that came with the CPU. If you
have no instructions, do the following:

3. Carefully align the CPU so it is parallel to the socket and the notch on the corner of the
CPU corresponds with the notch on the inside of the socket. Gently slide the CPU in. It
should insert easily. If it doesn‘t, it is probably not installed correctly or the lever is not fully
released.

4. Press the lever down. The plate will slide forward. You will feel some resistance as the
pressure starts to secure the CPU in the socket. This is normal and will not damage the
CPU.

When the CPU is installed, the lever should snap into place at the side of the socket.
Note: To remove a CPU, pull the lever out to the side a little and raise it as far as it will go. Lift out

the CPU chip.
Note also that the CPU clock speed and operating voltage is automatically detected by the SBC

and there are no jumper options for these settings.

2.2 DRAM (DIMM) Installation & Upgrade

Doc # 98-37844-00 Rev. 1.1 02/12/02

PEGASUS

You can install anywhere from 8MB to 256MB of on-board DRAM memory using one 8, 16, 32,
64, 128 or 256MB 168-pin DIMM. Note: The modules can only fit into a socket one way and
their gold fingers must point down into the DIMM socket. The procedure for installing DIMMs
appears below. Please follow these steps carefully.

1. Ensure that all power supplies to the system are switched off.

2. Locate the DIMM near the Pegasus DIMM socket so that its gold fingers point down into the
DIMM socket.

3. The DIMM module has two notches on its edge connector. Ensure that the notches are facing
away from the CPU.

4. Gently push the DIMM vertically down until the ejector tabs of the DIMM sockets snap into
place.

2.3 Jumpers

The Pegasus SBC contains various jumpers that allow configuration of the board to suit your
application. Table 2-1 lists the function of each Pegasus jumper:

Jumper Function

J1 Firmware hub lock\unlock
J2 PC104 +VIO select
J3 CMOS battery normal\clear CMOS
J4 CPLD Program Connector
J5 CPLD Program Connector
J6 Internal speaker enable\disable
J7 IDE tri-state buffer control
