PPREFACE
HOT-681 is a highly integrated IBM PC/ATX compatible system board designed to
meet the industry's most demanding desktop applications.
Based on the Intel 82440BX AGPset chipset which support up to 500MHz PPGA
Celeron processor with MMX technology.
HOT-681 is equipped with an Accelerated Graphics Port (A.G.P.), a high-performance
interconnect for graphic-intensive application, such as 3D applications. The A.G.P. is
independent of the PCI bus and is designed to exclusively use with graphical-display
devices. The HOT-681 supports 3.3 V A.G.P. devices with data transfer rates up to 133
MHz, allowing data throughput of 500 MB/sec.
The Intel's 82440BX AGPset chipset provides an integrated Bus Mastering IDE control-
ler with two high performance IDE interfaces which allows up to four IDE devices
connection and up to 33 MB/sec of data transfer rates.
The on-board I/O controller provides standard PC I/O functions:
floppy drive interface, two FIFO serial ports, an InDA device port and a SPP/EPP/ECP
capable parallel port.
HOT-681 is built with four PCI local bus slots providing a high bandwidth data path for
data-movement intensive functions such as graphics, and with three ISA slot.
HOT-681 provides the foundation for cost effective, high performance and highly
expandable platforms, which delivers the latest in the Intel PPGA Celeron processor and
new advanced chipset technology.

2HARDWARECONFIGURATION
HOT-681 mainboard provides a 370-pin ZIF Socket370 for Intel PPGA Celeron CPU. The
CPU that came with the mainboard should have a fan attached to it to prevent overheating. If
this is not the case then purchase a fan before you turn on your system.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF Socket370
and open it by first pulling the lever sideways away from the socket then upwards to a 90-
degree right angle. Insert the CPU with the correct orientation as shown.(Figure 2-1) Use
the notched corner of the CPU as your guide. The notched corner should point towards the
end of the lever. Notice that there are two blank area where one hole is missing from that
corner of the square array of pin holes. Because the CPU has a corner pin for two of the four
corner, the CPU will only fit in the one orientationn, hold down on the CPU and close the
socket’s lever.
The Installation PPGA Celeron Processor

Then you should have a CPU fan that
will cover the face of the CPU. Apply
thermal jelly to the CPU metallic top and
then install the fan onto the CPU. (Figure

Jumpers
HOT-681 mainboard features a clock generator to provide adjustable system clock frequency.
JP5 is a 6-pin jumpers which determine the system clock frequency 66 MHz to 133 MHz. and
JP6 is a 8-pin jumper which determine the processor clock ratio from 3.5X to 8X.
Several hardware settings are made through the use of jumper caps to connect jumper pins on
the main board. The jumper's pin 1 on main board will be on the top or on the left when hold-
ing the main board with the keyboard connector away from yourself.
Jumpers with two pins will be shown as for Close (On) and for Open (Off).
To connect the pins, simply place a plastic jumper cap over the two pins.

Special Tip for User's Reference Only
HOT-681 mainboard provides a special JumperJP4
to overspeed your 66 MHz based Intel PPGA Celeron
processor to 100 MHz when jumper group JP6 set to
MANUAL.
Normally, CPU Host Clock 100 ~ 133 MHz are not
available for 66 MHz based processor no matter Soft-
Configure or Hard-Configure.
But, when pull out mini jumper from JP4 (let it open),
the user can Hard-Configure your 66 MHz based
processor to 100 MHz based. For example, overspeed
your 333 MHz (66 MHz x 5) PPGA Celeron to
400 MHz (100 x 4) or more. Figure 2-4

Clear CMOS - JP9
HOT-681 mainboard supports jumper JP9 for discharging mainboard's CMOS memory.
This jumper can clear the CMOS data stored in the Giga I/O chip. To clear the CMOS data
please follow listed steps:
1) Turn off the PC,
2) Remove mini jumper from JP9 pin 1-2,
3) Insert mini jumper to JP9 pin 2-3 for a brief while,
4) Remove mini jumper from JP9 in 2-3,
5) Reinsert mini jumper to JP9 pin 1-2,
6) Turn on the PC.
Keyboard & PS/2 Mouse Power-On Setting - JP2
HOT-681 mainboard provides an optional power-on function by stroke any key (or hot-key)
on keyboard or double click on PS/2 mouse.
Note: Power-on by serial mouse is not supported
JP2 is the jumper used to set the functions of keyboard & PS/2 mouse power-on Enabled or
Disabled.
When you enabled K/B & PS/2 Mouse Power-ON function, you also have to set the proper
item on POWER ON function category of Integrated Peripherals of BIOS setup.

The HOT-681 mainboard provides three 168-pin DIMM sockets that make it possible to
install from 8MB up to 256MB of SDRAM. The DIMM socket support 8MB, 16MB,
32MB, 64MB, 128MB and 256MB 3.3V single- or double- side SDRAM DIMM.
The three DIMM sockets are arranged in three banks of one socket each, Each bank
provides a 64/72-bit wide data path.
HOT-681 provides optional data integrity features including EC (Error Checking) or
ECC (Error Checking and Correcting) in the memory array. EC mode provides single
and multiple bit error detection. In ECC mode, during reads from the DRAM, the HOT-
681 provides error checking and correction of the data.
To support ECC, you must use true (opposed to phantom parity generated by TTL chips)
72-bit parity-type DIMM for all modules.
Install memory in any or all of the banks in any combination as follows:

only examples to let you have a more clear understanding of the updating process.
How to Begin
1. Please type “awdflash” and press the ENTER key to begin the updating process.
2. Once you enter, you will see a main menu displaying:
3. Move the cursor to “File Name to Program: “
4. Type the program name “test.bin”, and then press the ENTER key.
5. At the bottom of the menu, you will be requested to answer:
“Do You Want to Save BIOS (Y/N)? “

- 17 -
If “Yes”
To save the old BIOS:
1. Please respond “Y”, and then press the ENTER key.
2. Move the cursor to “File Name to Save: “
3. Type file name “TEST.BIN”, and then press the ENTER key. (Your old BIOS will be
saved in the file name you create. In this case, the old BIOS is saved in the file
name,681.OLD).
4. Then you will be requested to answer:
“Are You Sure to Program (Y/N)? “
5. Type “Y” to begin programming, and press the ENTER key.
6. When the programming is finished, the showing message will appear:
7. Once you see the showing message “Power Off or Reset System”, please restart your
system.
8. When you power on the computer again, you will find your old BIOS has already
been successfully updated.
To view a complete usage of FLASH utility, please type “awdflash /?” and press the
ENTERkey.
Notes About Award Flash Utility
Please note that Award Flash Utility cannot run under EMM386 or QEMM. Thus,
when executing the command “awdflash”, an error message will appear:
“Error Message: Fail — Due to EMM386 or QEMM !”

BIOSSETUP
The 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 RAM so that it retains
the Setup information when the power is turned off.
Entering Setup
Power on the computer and press <Del> immediately will allow you to enter Setup. The
other way to enter Setup is to power on the computer, when the below message appear
briefly at the bottom of the screen during the POST (Power On Self Test), press <Del> key
or simultaneously press <Ctrl>,<Alt>, and <Esc> keys.
“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 the ON or pressing the “RESET” button on the system
case. You may also restart by simultaneously press <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”
