Preface
HOT-553 mainboard is a highly integrated IBM PC/AT compatible system
board. The design will accept Intel Pentium, Cyrix 6x86 and AMD5l<86 pro
cessors and also features high-performance pipeline burst secondary cache
memory support with size of 256KB and 512KB. The memory subsystem is
designed to support up to 256 MB of EDO RAM or standard Fast Page DRAM
in standard 72-pin SIMM socket. A type 7 Pentium processor socket provides
access to future processor enhancements.
HOT-553 provides a new level of I/O integration. Intel's 82430HX PCiset
chip set provides increased integration and improved performance over other
chip set designs. The 82430HX PCIset chipset provides an integrated Bus
Mastering IDE controller with two high performance IDE interfaces for up to
four IDE devices.
The onboard Super I/O controller provides the standard PC I/O functions;
floppy interface, two FIFO serial ports, an IR device port and a SPP/EPP/ECP
capable parallel port.
Up to four PCI local bus slots provide a high bandwidth data path for data-
movement intensive functions such as graphics, and up to four ISA slots com
plete the I/O function.
The HOT-553 provides the foundation for cost effective, high performance,
highly expandable platforms, which deliver the latest in Pentium processor
and I/O standard

CPU Clock Speed Selection
HOT-553 mainboarcl features a clock generator to provide adjustable sys
tem clock frequency. jP15, jP16 and jP79 are all 2-pin jumpers which
determine the system clock frequency from 40MHz to 66MH2.
HOT-553 mainboard also provides jP3 and JP58 to figure up CPtJ core
clock multiplier. By inserting or removing jumper caps on JP3 and jP58
the user can change the Host Bus Clock/CPU Core Clock ratio from
1 : 1.5 to 1 : 3.

Onboard regulator & VRM Selection - JP50;51^56^57
HOT-553 mainboard is designed an onboard voltage regulator to pro
vide 3.3V ranger for pentium, Cyrix 6x86 and AMD K5, and optional
VRM (voltage regulator module) socket for VRM to provide 3.3/2.5V
ranger for P55C processors.
Normally, VRM supports both voltage level , but some particular VRM,
they only provide 2.5V and require onboard regulator to complement
3.3V to P55C.

Cache Type Selection
HOT-553 mainboard support onboard pipeline burst cache SRAM, and
pipeline burst cache module.
Onboard pipeline burst cache RAM
A factory option on HOT-553 mainboard is an integrated 256KB external
cache implemented with two 32K x 32 pipeline burst SRAM devices
soldered to the mainboard. A 32KB x 8 external Tag SRAM is required.
Pipeline Burst cache module
If the HOT-553 is ordered with no cache installed, the cache can be
added later in a field upgrade by installing a 256KB pipeline burst cache
module into the CELP socket.
If factory option on HOT-553 mainboard integrate 256KB pipeline burst
cache installed already, the cache size can be field upgrade to 512KB by
installing a 256KB pipeline burst cache module into the CELP socket.
(please refer to section of "Pipeline Burst Type Cache Size Selection")
110 User's Manual

HOT-553 mainboard supports 256KB or 512KB pipeline burst cache
size.
If the HOT-553 is ordered with no cache installed, the cache can be field
upgraded by installing a first 256KB pipeline burst cache module into
the CELP socket.
If factory option on HOT-553 mainboard integrate 256KB pipeline burst
cache onboard mounted already, the cache size can be field upgraded to
512KB by installing a secondary 256KB pipeline burst cache module
into the CELP socket.
256KB Cache Memory
1 as
On mainboard integrate 256KB pipeline burst cache mounted, or a first
256KB pipeline burst cache module in the CELP socket.
512KB Cache Memory
On mainboard integrate 256KB pipeline burst cache mounted and a
secondary 256KB pipeline burst cache module in the CELP socket.
Note : There are some technical difference between first 256KB pipeline
burst cache module and secondary one, if 512KB cache memory are
required, please contact your supplier for help.

Parallel Port DREQ Selection - JP60, JP61
HOT-553 mainboard onboard parallel port supports ECP mode (Extended
Capabilities Port), and provide two available DMA Request lines DREQl
and DREQ3 for it.
When an ECP mode device is in use, the user may assign DREQl or
DREQ3 for parallel port. If SPP/EPP mode is selected, the user may ignore
those jumpers.

Clear Password - JP72
Allows system password to be cleared by shorting jumper jP72 and
turning the system on, "Password is cleared by jumper, (JCP)!" message
will shown up on power-on screen. The system should then be turned off
and the jumper JP72 should be returned to OPEN to restore normal
operation. The procedure should only be done if the user password has
been forgotten. (This function may not available when Cyrix 6x86 CPU is
in use)

Flash EPROM Jumper - JP9
HOT-553 mainboard supports two types of flash EPROM, 5 volt and 12
volt. By setting up jumper jP9, you can update both types of flash EPROM
with new system BIOS files as they come available.
JP9 open for 5V, Pin 2-3 close for 12V.
BIOS UPGRADES
Flash memory makes distributing BIOS upgrades easy. A new version of
/ the BIOS can be installed from a diskette.
The flash upgrade utility, Awdflash.exe, has two notice for BIOS upgrades.
Flash utility can't work under protected/virtual mode. Memory
manager like QEMM.386, EMM386 should not be loaded, (or
Simply bypass all config.sys and autoexec.bat on system boot
up.
Flash utility supports both 5V and 12V Flash EEPROM.
Clear CMOS-jPII
HOT-553 mainboard supports jumper |P11 for discharge mainboard's
CMOS memory. The CMOS memory retains the system configuration
information in the component of R.T.C.
You should short this jumper for a moment when you wish to clear
CMOS memory, and then make sure open this jumper for normal opera
tion to retain your new CMOS data.
Note: Clear CMOS & R.T.C function available only when "DS12887A "
or "DS128887" are in use.
There are different ways to discharge CMOS memory between
"DS12887A" and "DS12B887".
DS12887A - Turn off power, close jumper JP11 for 2 to 3 seconds then
release and CMOS will be discharged.
DS12B887 - Close jumper JP11, turn on power durning 2 to 3 seconds
then release jP11 and turn off power, CMOS will be discharged.

Chapter^ Award BIOS Setup
HOT-553'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 RAM so that it retains the Setup information when the
power is turned off.
Bntering 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 com
puter, 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.
TO ENTER SETUP BEFORE BOOT PRESS CTRL-ALT-ESC OR DEL KEY
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,
