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 HS-6252 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
PROTECTION

General Description

The HS-6252 is a 133MHz FSB VIA VT8601 chipset-based board
designed for PCI-ISA Bus with VIA C3 800MHz Embedded CPU.
These features combine and make the HS-6252 an ideal all-in-one
industrial single board computer. Additional features include an
enhanced I/O with CRT, Dual LAN, and 4 COM ports interface.

Its onboard ATA/33/66/100 to IDE drive interface architecture allows
the HS-6252 to support data transfers of 33, 66 or 100MB/sec. to each
IDE drive connection. Designed with the VIA VT8601 core logic
chipset, the board supports VIA C3 800MHz Embedded CPU. The VIA
VT8601 integrated Trident 3D supporting AGP Bus.

For suitable installation into any size system with 8/16/32-bit ISA and/or
PCI slots operation, the board’s advanced PCI-ISA bus add-on feature
allows user to easily obtain both ISA's 16-bit and PCI's 32-bit full set
signals from a half-size PCI-ISA slot. System memory is also sufficient
with the two DIMM sockets that can support up to 1GB.

1

Additional onboard connectors include an advanced USB and IrDA

3.22 Watchdog Timer

There are three access cycles of Watch-Dog Timer as

Enable, Refresh
and Disable are the three access cycles of Watchdog Timer. The
Enable cycle proceeds via READ PORT 443H whereas the Disable
cycle proceeds via READ PORT 045H. A continued Enable cycle after
a first Enable cycle means Refresh.

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 to
re-start or a NMI cycle to the CPU transpires when such error happens.
Jumper JP6 is used to select the function of Watchdog Timer.

The Watchdog Timer is disabled after the system Power-On. It can be
enabled via an Enable cycle and reading the control port (443H), or via
a Refresh cycle and reading the control port (443H), or via a Disable
cycle and reading the disable control port (045H).

After an Enable cycle of WDT, user must immediately execute a
Refresh cycle to WDT before its period setting comes to an end every
1, 2, 10, 20, 110 or 220 seconds. If the Refresh cycle does not activate
before WDT period cycle, the onboard WDT architecture will issue a
Reset or NMI cycle to the system. There are three I/O ports that control
the Watchdog Timer.

Chapter 4

AMI BIOS Setup

The HS-6252 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 <Del> immediately after switching the system on, or

2. By pressing the <Del> 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 <Ctrl>, <Alt>, and <Delete> keys. If you do
not press the keys at the correct time and the system does not boot, an
error message will be displayed and you will again be asked to...

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

31

4.2 Using Setup

In general, you use the arrow keys to highlight items, press <Enter> to
select, use the <PageUp> and <PageDown> keys to change entries,
press <F1> for help and press <Esc> to quit. The following table
provides more detail about how to navigate in the Setup program using

4.8 PCI / Plug and Play Setup

This section describes configuring the PCI bus system. PCI, or
Personal Computer Interconnect, is a system that allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when
communicating with its own special components. This section covers
some very technical items and it is strongly recommended that only
experienced users should make any changes to the default settings.

4.9 Peripheral Setup

The IDE hard drive controllers can support up to two separate hard
drives. These drives have a master/slave relationship that is
determined by the cabling configuration used to attach them to the
controller. Your system supports two IDE controllers--a primary and a
secondary--so you can install up to four separate hard disks.

PIO means Programmed Input/Output. Rather than having the BIOS
issue a series of commands to affect the transfer to or from the disk
drive, PIO allows the BIOS to tell the controller what it wants and then
let the controller and the CPU perform the complete task by them. This
is much simpler and more efficient (also faster).
