Features and Specifications
Processor Upgrade
The 586ITBD is equipped with a 321-pin ZIF socket (IntelSocket
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 2.0V, 2.8V,
2.9V, 3.2V, 3.3V and 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+ and 6x86MX-PR166/PR200
•AMDK5 PR90/PR100/PR120/PR133/PR166
•AMDK6/166, K6/200, K6/233, K6/266
Chipset
•Intel82430TX PCIset chipset
System Memory
The 586ITBD 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

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 (ATX power
supply only)
ACPI Specification and OS Directed Power
Management (ATX power supply only)
The 586ITBD 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 586ITBD 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 586ITBD system board allows your
system to automatically wake up on the set day and time. Set the
day and time you would like your system to power on in the
“Resume By Alarm” field (Power Management Setup) of the Award
BIOS.
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 (Power
Management Setup) of the Award BIOS and set JP2 to the COM
port where your modem is connected.
Note:
This feature supports external modem only.

Damage Free Intelligence
•Monitors processor temperature and overheat alarm.
If the temperature of the processor is over 85oC, an alarm will
sound and the Green LED will illuminate warning you of system
overheat.
Some of the most common causes leading to high temperature
are:
-The fan is not functioning normally or has stopped. Turn off
your system and replace the fan.
-The space clearance of the processor, fan and heat sink is
inadequate to maintain proper airflow and heat dissipation.
Refer to the Clearance Requirements section in Chapter 2 of
this manual.
-The chassis or cabinet has poor ventilation.
•Monitors 5V and 12V power voltages and failure alarm.
The 586ITBD is able to detect the output voltage of your
power supply. If the output voltage is over or under 5V or 12V
(±10%), an alarm will sound warning you of voltage irregularity.
Some of the most common causes leading to unstable output
voltage of a power supply are:
-The power supply is not functioning normally. Turn off your
system and replace the power supply.
-The AC input from the power outlet to your system is
unstable.
•Automatic processor fan control to save energy, prevent system
overheat, prolong fan life and implement silent system.
With the system’s power switched on, the processor’s fan will
rotate only if the temperature of the processor is over 25oC.

Dual Function Power Button
Dual Function Power Button allows two distinct OFF modes. In
Sleep mode, a PC powers down but not off. In Soft-Off, a PC shuts
down but requires a reboot to "awaken" it.
“Soft-Off By PWR-BTTN” in the Power Management Setup 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 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
FDD Interface
•One floppy drive interface supports two 360KB, 720KB, 1.2MB,
1.44MB, or 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 or AT keyboard port
•One 20-pin ATX power supply connector
•One 12-pin standard AT power supply connector
