Safety Instructions 
Integrated circuits on computer boards are sensitive to static electricity. To 
avoid damaging chips from electrostatic discharge, observe the following 
precautions: 
� Do not remove boards or integrated circuits from their anti-static packaging 
until you are ready to install them. 
� Before handling a board or integrated circuit, touch an unpainted portion of 
the system unit chassis for a few seconds. This helps to discharge any static 
electricity on your body. 
� Wear a wrist-grounding strap, available from most electronic component 
stores, when handling boards and components. Fasten the ALLIGATOR clip 
of the strap to the end of the shielded wire lead from a grounded object. 
Please wear and connect the strap before handle the product to ensure 
harmlessly discharge any static electricity through the strap. 
� Please use an anti-static pad when putting down any components or parts or 
tools outside the computer. You may also use an anti-static bag instead of 
the pad. Please inquire from your local supplier for additional assistance in 
finding the necessary anti-static gadgets. 
NOTE: DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE 
COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC 
PROTECTIONS.
Chapter 1 
General Description 
 
The HS-1745 is an Intel® 945GME GMCH chipset-based board 
designed. The HS-1745 is an ideal all-in-one mITX board. Additional 
features include an enhanced I/O with CF, DVI/CRT/LVDS, TV-Out, 
dual Giga LAN, audio, SPDIF, SATA, 6 COM, IrDA, and USB2.0 
interfaces. 
Designed with the Intel® 945GME GMCH, the board supports Intel® 
Core™ 2 Duo/Core™ Duo/Core™ Solo processor 1.66~2.33GHz. 
Its onboard ATA/33/66/100 to IDE drive interface architecture allows 
the HS-1745 to support data transfers of 33, 66 or 100MB/sec. to one 
IDE drive connection.  The Intel® ICH7-M serial ATA controller with two 
ports supporting transfer rates up to 150MB/sec.  
Onboard Intel® 945GME GMCH for CRT display with DVMT or 
CHRONTEL 7307 for DVI display supporting up to 2048 x 1536. It also 
supports 18-bit single channel/36-bit dual channel LVDS interface. 
System memory is also sufficient with the one SO-DDRII socket that 
can support up to 1GB. Additional onboard connectors include an 
advanced USB2.0 port providing faster data transmission. And two 
external RJ-45 connectors for 10/100 Based Ethernet use. 
To ensure the reliability in an unmanned or standalone system, the 
watchdog timer (WDT) onboard HS-1745 is designed with software 
that does not need the arithmetical functions of a real-time clock chip. If 
any program causes unexpected halts to the system, the onboard WDT 
will automatically reset the CPU or generate an interrupt to resolve 
such condition.

Unpacking 
2.1 Opening the Delivery Package 
The HS-1745 is packed in an anti-static bag. The board has 
components that are easily damaged by static electricity. Do not 
remove the anti-static wrapping until proper precautions have been 
taken. Safety Instructions in front of this manual describe anti-static 
precautions and procedures.  
2.2 Inspection 
After unpacking the board, place it on a raised surface and carefully 
inspect the board for any damage that might have occurred during 
shipment. Ground the board and exercise extreme care to prevent 
damage to the board from static electricity. 
Integrated circuits will sometimes come out of their sockets during 
shipment. Examine all integrated circuits, particularly the BIOS, 
processor, memory modules, ROM-Disk, and keyboard controller chip 
to ensure that they are firmly seated. The HS-1745 delivery package 
contains the following items:

3.20 Watchdog Timer 
Once the Enable cycle is active a Refresh cycle is requested before the 
time-out period. This restarts counting of the WDT period. When the 
time counting goes over the period preset of WDT, it will assume that 
the program operation is abnormal. A system reset signal will restart 
when such error happens. 
The following sample programs show how to enable, disable and 
refresh the watchdog timer:

AMI BIOS Setup 
The HS-1745 uses AMI BIOS for the system configuration. The AMI 
BIOS setup program is designed to provide the maximum flexibility in 
configuring the system by offering various options that could be 
selected for end-user requirements. This chapter is written to assist 
you in the proper usage of these features. 
4.1 Starting Setup 
The AMI BIOS is immediately activated when you first power on the 
computer. The BIOS reads the system information contained in the 
CMOS and begins the process of checking out the system and 
configuring it. When it finishes, the BIOS will seek an operating system 
on one of the disks and then launch and turn control over to the 
operating system. 
While the BIOS is in control, the Setup program can be activated in one 
of two ways: 
1. By pressing  immediately after switching the system on, or 
2. By pressing the  key when the following message appears 
briefly at the bottom of the screen during the POST (Power On Self 
Test). 
Press DEL to enter SETUP. 
If the message disappears before you respond and you still wish to 
enter Setup, restart the system to try again by turning it OFF then ON or 
pressing the "RESET" button on the system case. You may also restart 
by simultaneously pressing

What they say about us
FANTASTIC RESOURCE
One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!
Bucher Emhart Glass
EXCELLENT SERVICE
With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.
Fuji
HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
