Chapter 2. Hardware Setup
2.1 Installation Procedure
1. Jumper settings (BIOS and CPU)
2. Installation of CPU
3. Installation of Memory
4. I/O Connections & Panel Connections
2.1.1 Jumper Settings
In this manual , (1-2) represents the first and second pins of the jumper. (2-3) represents the
second and third pins of the jumper. On the motherboard, you will see two sets of jumpers with
different color jumper caps:
Yellow Jumper Caps : Sets the Function of Flash CMOS JRTC
Green Jumper Caps : Sets the type and speed of CPU
JF0, JF1, JF2, JF3 (for PCB B or earlier version)
JF (for PCB E or later version)
WARNING: Electronic parts are Static sensitive. To prevent damage to the computer and its parts
please take the following measures.
Work on a surface such as concrete, linoleum or hard wood floor.
Ground your self with either a properly installed grounding strap or by touching a major
electrical appliance long enough to discharge the static.
2.1.2 Clearing the CMOS (Yellow Jumper Caps)
JRTC : CMOS Function Selection
1-2 : Clear data
2-3 : Normal Operation (Default Setting)
How to Clear the CMOS Setting:
1. Turn off the power.
2. Remove ATX power cable from power connector.
3. Remove Yellow Jumper Cap from JRTC (2-3) and put on JRTC (1-2)to remove the CMOS
setting.
4. Remove Yellow Jumper Cap from JRTC (1-2) and put on JRTC (2-3).
5. Connect ATX power cable back to power connector.
6. Turn on the power.
7. While the system reboots, press <DEL> key to set the BIOS setup.
2.1.3 CPU Voltage Setting
The motherboard supports CPU VID function, the CPU core voltage is automatically detected.
Over-current Protection
This switching regulator circuit is designed onboard to support CPU over-current protection. It
enhances the protection of CPU.
ATX switching power supply----5V---->circuit onboard power regulator---->over-current protection----
>CPU core voltage.
Note: Although we have implemented protection circuit try to prevent any human operating mistake,
there is still certain risk that CPU installed on this motherboard may be damaged because of
component failure, human operating error or unknown nature reason. We cannot guaranty the
protection circuit will always work perfectly.
2.1.4 CPU Bus Clock Setting
K7TA series supports DDR (Double Data Rate) transfer on Socket A CPU address and data buses. EV6 Bus is the
technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and failing clock edge
to transfer data.
EV6 Bus speed = CPU external bus clock x 2
For example, 200MHz EV6 bus is actually using 100MHz external bus clock, but the equivalent speed is 200MHz.
Any attempts to push beyond product specification are not recommended.

CPU Bus Clock EV6 Bus Clock JF0 JF1 JF2 JF3
100 200 1-2 2-3 1-2 1-2

2.2 Installation of CPU
Before installing CPU, make sure the power is off. Locate the level bar on the PGA462 ZIF socket. Push level bar
away from the socket and pull upward 90 degrees. Insert the CPU into the socket. Be careful of CPU orientation.
Make sure the notch of the CPU corresponds with the white dot on the ZIF socket (the corner without pin socket). Do
not push in the CPU. Make sure all pins are aligned with the CPU socket. ON the level bar.
2.3 Installation of Memory
The motherboard has 3x168-pin 64-bit Dual Inline Memory Module (DIMM) sockets divided into 3 banks.
You can install 3.3V Unbuffered PC100/133-compliant Synchronous DRAM (SDRAM) memory. This will
increase the system reliability.
2.3.1 Installation of 168-pin DIMM (Dual Inline Memory Module)
1. Before inserting the DIMM, make sure the pin1 of the DIMM matches with the pin1 on the
DIMM socket.
2. Insert DIMM into the DIMM sockets at a 90-degree angle and press down.
2.3.2 Removal of 168-pin DIMM
Press the holding clips on both sides of the socket outward to release the DIMM.
Gently pull the DIMM out of the socket.
2.3.3 Memory Configuration
There is no jumper setting required for the memory size or type. It is automatically detected by the
system BIOS, and the total memory size is to add them together.
DIMM Socket DIMM Modules
DIMM1 PC100/PC133, 8, 16, 32, 64, 128, 256, 512MB
