8KTA Features:
8KTA is based on the AMD Socket A Processors operating at 600
~ 1GHz on Socket A.
Designed with VIA KT133 AGPset.
Supports up to 768MB of DRAM (minimum of 32 MB) on board
8KTA will support Error Checking and Correcting (ECC) when using
parity SDRAM memory modules. This will detect multiple bit errors and
correct 1-bit memory errors.
Supports (1) 16 bit ISA slots, (6) 32 bit PCI slots, (1) 4X AGP slot and
provides (2) independent high performance PCI IDE interfaces capable of
supporting PIO Mode 3/4 and Ultra DMA 33/66 devices.
The 8KTA supports (6) PCI Bus Master slots and a jumperless PCI
INT# control scheme which reduces configuration confusion when plug
ging in PCI card(s).
Features8KTA
Supports ATAPI (e.g. CD-ROM) devices on both Primary and Secondary
IDE interfaces.
Designed with on chip Multi I/O: (1) floppy port, (1) parallel port (EPP,
ECP), and (2) serial ports (16550 Fast UART).
Note: Japanese Floppy 3 mode is also supported
Features Award Plug & Play BIOS. With Flash Memory you can always
upgrade to the current BIOS as they are released.
8KTA utilizes a Lithium battery which provides environmental
protection and longer battery life.

Features8KTA
4 USB ports provided, 2 ports are onboard and another 2 USB ports as optional.
Built-in ATX 20-pin power supply connector.
Software power-down when using Windows® 95/98 or Windows®2000.
Supports ring-in feature (remote power-on through external modem,
allows system to be turned on remotely).
Resume by Alarm - Allows your system to turn on at a preselected time.
Power Loss Recovery - In the event of a power outage your system will
automatically turn itself back on without user intervention.
Supports CPU Hardware sleep and SMM (System Management Mode).
Supports Keyboard power ON function (KBPO).
Built-in WOL (Wake-up On LAN) Connector.
Built-in AC97 PCI Audio.
Supports STR (Suspend to RAM) function.
Supports CPU Front Side Bus setting via BIOS.

Easy Installation Procedure
The following must be completed before powering on your new system:
CPU Insertion
Jumper Settings
System memory Configuration
Device Connectors
CPU Insertion
CPU Insertion: (use AMD AthlonTM as reference)
Step 1
Open the socket by raising the actuation
lever.
Figure 2
Figure 3
Step 2
Insert the processor.
Ensure proper pin 1 orientation by aligning
the FC-PGA corner marking with the
socket corner closest to the actuation arm
tip. The pin field is keyed to prevent misoriented insertion.
Dont force processor into socket. If it does
not go in easily, check for mis-orientation and
debris.
Make sure the processor is fully inserted
into the socket on all sides.

Installation8KTA
Step 3
Close the socket by lowering and
locking the actuation lever.

Step 4
Thermal conductive and qualified heatsink recommended by AMD are a must to
avoid CPU overheat and burned.

System Memory Configuration
Memory Layout
The 8KTA supports (3) PC133 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs is for SDRAM (Synchronous DRAM) only.
DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or
125MHz (8ns) bus speed.
If you use both 50ns and 60ns memory you must configure
your BIOS to read 60ns.
When using Synchronous DRAM we recommend using the
4 clock variety over the 2 clock.
Figure 2 and Table 1 show several possible memory configurations.

* SDRAM only supports 32, 64, 128, 256MB DIMM modules.
* We recommend to use PC100 Memory Module for bus speed 100MHz and
PC133 Memory for bus speed over 100MHz.
* Using non-compliant memory with higher bus speed (over clocking) may
severely compromise the integrity of the system.

(This is connected to the power button on the case. Using the Soft-Off
by Pwr-BTTN feature, you can choose either Instant Off (turns system
off immediately), or 4 sec delay (you need to hold the button down for
4 seconds before the system turns off). When the system is in 4 sec
delay mode, there is a special feature to make the system to go into
suspend mode when the button is pressed momentarily).
