HOT-555 User's Manual 4
HOT-555 mainboard is a highly integrated IBM PC/AT compatible system
board. The design will accept Intel Pentium, Cyrix 6x86 and AMD5k86
processors and also features high-performance pipeline burst secondary cache
memory support with size of 256KB. The memory subsystem is designed to
support up to 128 MB of EDO RAM, Standard Fast Page DRAM and SDRAM
in standard 72-pin SIMM socket and 168-pin DIMM socket. A type 7 Pentium
processor socket provides access to future processor enhancements.
HOT-555 provides a new level of I/O integration. Intel's 82430VX PCIset
chipset provides increased integration and improved performance over other
chipset designs. The 82430VX 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 IrDA device port and a SPP/EPP/
ECP capable parallel port.
Up to three PCI local bus slots provide a high bandwidth data path for data-
movement intensive functions such as graphics, and up to three ISA slots
complete the I/O function.
The HOT-555 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-555 mainboard features a clock generator to provide adjustable system
clock frequency. Jumpers JP27 and JP28 determine the system clock
frequency from 50MHz to 66MHz.
HOT-555 mainboard also provides Jumpers JP23 and JP24 to figure up
CPU core clock multiplier. By inserting or removing jumper caps on JP23
and JP24, the user can change theHost Bus Clock/CPU Core Clock
ratio from 1 : 1.5 to 1 : 3.

HOT-555 User's Manual 10
HOT-555 mainboard supports jumperJP21 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 operation to retain
your new CMOS data.
Note: Clear CMOS & R.T.C function available only when "DS12887A"
or "DS12B887" are in use.
There are different ways to discharge CMOS memory between "DS12887A" and
"DS12B887".
DS12887A- Turn off power, close jumper JP21 for 2 to 3 seconds then release and
CMOS will be discharged.
DS12B887- Close jumper JP21, turn on power durning 2 to 3 seconds then release JP21
and turn off power, CMOS will be discharged.
Clear CMOS - JP21
Flash EPROM Jumper - JP18
HOT-555 mainboard supports two types of flash EPROM, 5 volt and 12
volt. By setting up jumper JP18, you can update both types of flash
EPROM with new system BIOS files as they come available.
JP18 Pin 2-3 Closed for 5V, Pin 1-2 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.

HOT-555 User's Manual 11
Clear Password - JP9
Allows system password to be cleared by shorting jumper JP9 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 JP9 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)

Chapter3Memory Configuration
The HOT-555 mainboard provides four 72-pin SIMM sockets and two 168-
pin DIMM sockets that make it possible to install up to 128MB of RAM.
The SIMM socket support 4MB, 8MB, 16MB, and 32MB single- or double-
side fast page or EDO DRAM modules. Memory timing requires 70 ns fast
page devices or, for optimum performance, 60 ns EDO DRAM or 70 ns
Synchronous DRAM may be used. Both parity and non-parity memory are
supported.
The four SIMM sockets are arranged in two banks of two sockets each and
the two DIMM sockets are arranged in two banks of one socket each. Each
bank provides a 64/72-bit wide data path.
Both SIMMs in a bank must be of the same memory size and type, although
the different types of memory may differ between banks. It is possible to
have 70 ns fast page DRAM in one bank and 60 ns EDO DRAM in the other.
The DIMM socket share the same address lines with SIMM socket, there
have some restriction of memory configuration, please refer to Table 3-1,
Table 3-2, and Table 3-3.

HOT-555'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.
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.
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,

typically 512K for systems with 512K memory installed on the
mainboard, or 640K for systems with 640K or more memory installed on
the mainboard.
Extended Memory
The BIOS determines how much extended memory is present during the
POST. This is the amount of memory located above 1MB in the CPU's
memory address map.
