Features and Specifications
Processor Upgrade
The system board is equipped with a 321-pin ZIF socket (Intel
Socket 7). This socket is designed for easy removal of an old
processor and easy insertion of an upgrade processor. The system
board is also equipped with a switching voltage regulator that
supports 2.1V to 3.5V core voltage for various processors.
•Intel Pentiumprocessor with MMXTM technology-166/200/
233MHz
•Intel Pentium90/100/120/133/150/166/200MHz
•Cyrix6x86L PR150+/PR166+/PR200+ and future 6x86MX
processors
•AMDK5 PR90/PR100/PR120/PR133/PR166
•AMDK6-166, K6-200, K6-233 and future K6 processors
Chipset
•Intel82430TX PCIset chipset
System Memory
The system board supports 8MB to 256MB of memory. It is
equipped with two DIMM and four SIMM sockets. The 168-pin
DIMM sockets use x64 EDO (60/70ns), fast page mode (60/70ns),
or SDRAM (10/12/13ns), 3.3V. The 72-pin SIMM sockets use EDO
or fast page mode, 60/70ns, x32 DRAM, 5V.
Cache Memory
•512KB pipeline burst, direct map write-back cache installed on
the system board.
BIOS
•Award BIOS, Windows95 Plug and Play compatible
•Flash EPROM for easy BIOS upgrades
•Supports DMI function

Energy Efficient Design
•System power management supported
•CPU stopped clock control
•Hardware supports SMI green mode
•Microsoft®/Intel®APM 1.2 compliant
•Soft Power supported - ACPI v1.0a specification
ACPI Specification and OS Directed Power
Management
The system board is designed to meet the ACPI (Advanced
Configuration Power Interface) specification. It has energy saving fea-
tures which enable operating systems to reliably manage and coor-
dinate power planes, PnP (Plug-and-Play) peripherals, and cooling
fans. The system board is PC 97 compliant. Microsoft's PC 97
"OnNow" design allows continual "power on" with reduced energy
consumption.
RTC Timer to Power On the System
The RTC installed on the system board allows your system to
automatically wake up on the set date and time. Set the date and
time you would like your system to power on in the “Resume By
Alarm” field of the Power Management Setup (Chapter 2).
Modem Wake-up/Ring-on
The Modem Wake-Up feature allows the sleeping (Suspend mode)
PC to wake-up to respond to incoming calls. The Modem Ring-on
feature allows the Soft Power Down (Soft-Off) PC to power on to
respond to incoming calls. Enable this function in the “Resume By
Ring” field of the Power Management Setup (Chapter 2). Make sure
to select an IRQ channel for the external modem in the “Modem
Use IRQ” field of the Power Management Setup and set JP11 to
the COM port where the modem is connected (Chapter 3).
Note:
This feature supports external modem only.

Suspend to Disk
The system board supports the Suspend to Disk function. With
the ZVHDD utility installed, the system is capable of storing all
information of the current operating session into the hard drive
before the system powers off. The saved data includes all the
programs and data files loaded into system memory during the
session. The operating session will resume exactly where you left off
the next time you power on the system. Refer to the “Suspend
Mode Option” field of the Power Management Setup (Chapter 2)
and the ZVHDD utility (Appendix E) for instructions on using this
function.
Damage Free Intelligence
•CPU Slow Down
The system board is capable of monitoring the temperature of
the processor. If the processor's fan fails to function or the
temperature of the processor exceeds 85oC, the system will
decrease CPU utilization by slowing down the CPU clock.. This
will prevent the processor from being damaged.
•Monitors processor temperature and overheat alarm
The system board is able to detect the temperature of the
processor. An alarm will sound in case of processor overheat.
Refer to Chipset Features Setup (Chapter 2).
•Monitors processor fan speed and failure alarm
The system board is able to detect the processor’s fan speed
(RPM - Revolutions Per Minute) and alerts you to attend to
any irregularity that may damage your system. Refer to Chipset
Features Setup (Chapter 2).
•Monitors power voltages and failure alarm
The system board is able to detect the chipset’s voltage and
output voltage of the power supply. An alarm will sound warning
you of voltage irregularity. Refer to Chipset Features Setup
(Chapter 2).
•Automatic fan control
With the system’s power switched on, the processor’s fan will
rotate only if the temperature of the processor is over 32oC. This

saves energy, prevents system overheat, prolongs fan life and
implements a silent system. Refer to the “CPU Fan Connector”
section (Appendix B) for more information.
Dual Function Power Button
Dual Function Power Button allows two distinct OFF modes. If you
accidentally pushed the power button, it enters the Suspend mode
and if released in less than 4 sec., the system returns to normal. The
purpose of this function is to prevent the system from powering off
in case you accidentally “hit” or pushed the power button. “Soft-Off
By PWR-BTTN” in the Power Management Setup (Chapter 2) allows
you to select the method of powering off your system.
HDD Interface
•Two PCI IDE interfaces support up to four IDE devices
•Ultra DMA/33 supported (Synchronous DMA mode - data
transfer rate up to a maximum of 33MB/sec.)
•PIO Mode 3 and Mode 4 Enhanced IDE (data transfer rate up
to 16.6MB/sec.)
•Bus mastering reduces CPU utilization during disk transfer
•ATAPI CD-ROM supported
•LS-120 and ZIP supported
FDD Interface
•One floppy drive interface supports up to 2.88MB floppy drives
Onboard I/O
•Two NS16C550A-compatible serial ports
•One SPP/ECP/EPP parallel port
•One PS/2 mouse port
•One PS/2 keyboard port
USB Ports
The system board is equipped with two USB ports. USB allows
data exchange between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
