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
Page 12
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
J8 PCI VIO select and PCI pin A26 select
Table 2-1
2.3.1 Locating Jumpers
All option jumpers begin with the Jx designator. They can be located as follows:
12
Page 13
Figure 2-1
PEGASUS
2.3.2 Setting Jumpers
The option jumpers configure the Pegasus to match the needs of your application. A jumper is the
simplest kind of electric switch. It consists of two metal pins and a small metal clip (often
protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you
connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3.
The jumpers are represented in this manual as follows:
A pair of needle-nose pliers is helpful when working with jumpers. If you have any doubts about
the best hardware configuration for your application, contact your local FlexStar distributor or
technical support representative before you make any changes.

3.0 Software Configuration
The Pegasus system BIOS and Remote Boot code is located in a 512 KB, 32-pin PLCC Flash
ROM device, designated U15. A single Flash chip holds the system BIOS, VGA BIOS, and
network Remote Boot code. All peripherals are configured via CMOS settings. This method
minimizes the number of chips and difficultly of configuration.
3.1 Remote Boot LAN Configuration
The Pegasus SBC is equipped with a high performance 32-bit Ethernet chipset, which is fully
compliant with IEEE 802.3 100 Mbps CSMA/CD standards. It is supported by all major network
operating systems. It is also both 100Base-T and 10Base-T compatible.
The Ethernet port provides a standard RJ-45 jack on board. The Ethernet device is also used to
remote boot the Pegasus in embedded applications (no HDD). The network boot feature is
combined within the system BIOS, which can be enabled/disabled in the BIOS setup. To setup the
BIOS correctly for remote booting, use the following procedure:
1. Boot up the Pegasus board with keyboard and monitor attached and press the DEL key to
enter the BIOS setup
2. Enter the ADVANCED BIOS FEATURES menu and se the following:
a) FIRST BOOT DEVICE = LAN.
b) SECOND BOOT DEVICE = FLOPPY.
c) THIRD BOOT DEVICE = HDD-0.
d) OTHER BOOT DEVICE = Enable.
3. Enter the INTEGRATED PERIPHERALS menu and set the following:
a) ON BOARD SCSI BOOT ROM = Disabled.
b) RPL LAN ROM RETRY TIMER = 125.
3.2 PCI SVGA Setup
The Pegasus has an on-board PCI SVGA interface via the Intel 810 chipset. The specifications
and features are described as follows:
The Pegasus uses the Intel 810 chipset for its PCI/SVGA controller. It supports most conventional
analog CRT monitors and flat panel displays that accept the standard VGA interface. The VGA
controller can drive CRT displays or color flat panel displays with resolutions up to 800 x 600 at
64K colors.
The only BIOS setup for the video is inside the STANDARD CMOS SETUP menu:
VIDEO = EGA/VGA.

4.0 Award BIOS Configuration
Award’s BIOS ROM has a built-in Setup program that allows users to modify the basic system
configuration. This type of information is stored in battery-backed CMOS RAM so that it retains
the Setup information when the power is turned off.
Note: The battery, a CR2032, is a non-rechargeable with an expected life of 10,000
hours when the board is powered off.
4.1 Entering Setup
Power on or reset the Pegasus and press <Del> immediately after the post boot-up BEEP. This
will allow you to enter Setup. The main setup menu contains a number of sub-menus each
denoted by a bullet on the left side of the menu name. There are also five direct menu functions:
Load Fail-Safe Defaults:
Select this function to reload all BIOS menu settings with the most conservative default values.
Note: Fail safe defaults are used for debugging purposes only.
Load Optimized Defaults:
Select this function to reload all BIOS menu items with all the default settings.
Set Password:
A password may be set to prevent un-authorized booting and operation. This password protection
only prevents the user from entering the setup menu. Note that the password protection may be
reset by clearing the CMOS memory via jumper J3.
Save & Exit Setup:
The SAVE & EXIT SETUP function allows any changes that may have been made to the BIOS
setup to be saved in non-volatile CMOS memory. After the changes are saved, the Pegasus will
re-boot.
Exit Without Saving:
This function will simply cause the Pegasus to re-boot without saving any changes made to any of
the setup menu items.

5.0 Programming the Watchdog Timer
The Pegasus is equipped with a watchdog timer that resets the CPU or generates an interrupt if
processing comes to a standstill for whatever reason. This feature ensures system reliability in
industrial standalone, or unmanned, environments.
In order to program the watchdog timer, you must write a program, which writes I/O port address
443 (hex). The output data is a value of time interval. The value range is from 01(hex) to 3E(hex),
and the related time interval is 1 sec. to 62 sec.
Data Time Interval
01 1 sec.
02 2 sec.
03 3 sec.
04 4 sec.
. .
. .
. .
3E 62 sec.
After the timer expires, your program must refresh the watchdog timer by rewriting the I/O port
443 (hex). When you want to disable the watchdog timer, your program should read I/O port 443
(hex).
