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 handling the HS-7238
to protect yourself from the discharge of 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
COMPONENT WITHOUT ALL NECESSARY ANTI-STATIC
PROTECTION.

Unpacking
2.1 Opening the Delivery Package
The HS-7238 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. Make sure all integrated circuits, particularly the BIOS,
processor, memory modules, ROM-Disk, and keyboard controller chip
are firmly seated. The HS-7238 delivery package contains the following
items:
HS-7238 Board x 1
Utility CD Disk x 1
ATA/100 IDE flat cable x 2
FDD flat cable x 1
Printer cable with bracket x 1
Two RS-232 COM Port cable with bracket x 1
8-pin USB split type cable with bracket x 1
PS/2 KB/MS transfer cable x 1
MIC/Audio 8-pin cable x 1

Chapter 3
Hardware Installation
This chapter provides the information on how to install the hardware
using the HS-7238. This chapter also contains information related to
jumper settings of switch, watchdog timer etc.
3.1 Before Installation
After confirming your package contents, you are now ready to install
your hardware. The following are important reminders and steps to
take before you begin with your installation process.
1. Make sure that all jumper settings match their default settings
and CMOS setup correctly. Refer to the sections on this chapter
for the default settings of each jumper. (Set JP2 1-2)
2. Go through the connections of all external devices and make
sure that they are installed properly and configured correctly
within the CMOS setup. Refer to the sections on this chapter
for the detailed information on the connectors.
3. Keep the manual and diskette in good condition for future
reference and use.
4. Ma ke sure your power supply is us ing for P4 only. One o f 4-pin
connectors is for +12V lead which should connect to PW2
connector of HS-7238.
NOTE:
Since AD22 has been assigned for ISA bridge at HS-7238, please
make sure do not use this address for other PCI cards to avoid
confliction. In order to get detailed information, please contact
technical support engineer.

3.19 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
re-start when such error happens.
The following sample programs show how to Enable, Disable and
Refresh the Watchdog Timer:
;---------------------------------------------------------------------------------; Enter the WDT function mode, interruptible double-write
