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.

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

3.4.1 DRAM Timing By SPD
If your DIMM memory have SPD ( Serial Presence Detect ) 8-pin IC on module, you can set this
option to Enabled. System will set your DRAM clock and timing from the SPD IC. If the option set as
Disabled, you must set the DRAM clock and timing from items below.
3.4.2 DRAM Clock
This item allows you to set the DRAM Clock. Options are 100MHz or 133MHz. Please set the item
according to your DRAM Clock.

This item allows you to set the SDRAM Latency Timer. Options are 2, 3.
3.4.4 Memory Hole
Enabling this feature reserves 15MB to 16MB memory address space to ISA expansion cards that
specifically require this setting. This makes the memory from 15MB and up unavailable to the
system. Expansion cards can only access memory up to 16MB.
3.4.5 PCI Master Pipeline Req
Enable this item to enhance PCI bus for better performance.
3.4.6 P2C/C2P Concurrency
When Disabled, CPU bus will be occupied during the entire PCI operation period.
3.4.7 Fast R-W Turn Around

DRAM optimization feature: If a memory read is addressed to a location whose latest write is being
held in a buffer before being written to memory, the read is satisfied through the buffer contents, and
the read is not sent to the DRAM.
3.4.8 System BIOS Cacheable
Allows the system BIOS to be cached for faster system performance.
3.4.9 Video RAM Cacheable
Enabled allows caching of the video RAM, resulting in better system performance. However, if any
program writes to this memory area, a system error may result.
3.4.10 AGP Aperture Size
Choose 4, 8, 16, 32, 64, 128MB. Memory-mapped, graphics data structures can reside in the
Graphics Aperture.
3.4.11 AGP-4X Mode
Set to Enabled if your AGP card supports the 4X mode, which transfers video data at 1066MB/s.
3.4.12 AGP Driving Control
This item is use for control AGP drive strength.
Auto: Setup AGP drive strength by default setting.
Manual: Setup AGP drive strength by manual setting.
3.4.13 AGP Driving Value
Key in a HEX number to control AGP output buffer drive strength. Min = 00, Max = FF.
3.4.14 OnChip USB
If your system contains a Universal Serial Bus controller and you have a USB peripheral, select
Enabled. The next option will become available.
3.4.15 USB Keyboard Support
This item lets you enable or disable the USB keyboard driver within the onboard BIOS.
3.4.16 OnChip Sound/Modem
Allows the motherboard's BIOS to detect whether you are using any sound/modem device. If a
sound/modem device is detected, the onboard sound/modem controller will be enabled; if no sound
/modem is detected, the onboard sound /modem controller will be disabled. If you want to use
different controller cards to connect sound and modem connectors, set these fields to Disabled.
3.4.17 CPU to PCI Write Buffer
When enabled, up to four D words of data can be written to the PCI bus without interrupting the CPU.
When disabled, a write buffer is not used and the CPU read cycle will not be completed until the PCI
bus signals that it is ready to receive the data.
3.4.18 PCI Dynamic Bursting
When enabled, data transfer on the PCI bus, where possible, make use of the high-performance PCI
bust protocol, in which greater amounts of data are transferred at a single command.
3.4.19 PCI Master 0 WS Write
When enabled, writes to the PCI bus are command with zero wait states.
3.4.20 PCI Delay Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select
Enabled to support compliance with PCI specification version 2.1.

3.4.21 PCI # 2 Access # 1 Retry
This item allows you enabled/disabled the PCI # 2 Access # 1 Retry.
3.4.22 AGP Master 1 WS Write
This implements a single delay when writing to the AGP Bus. By default, two-wait states are used by
the system, allowing for greater stability.
3.4.23 AGP Master 1 WS Read
This implements a single delay when reading to the AGP Bus. By default, two-wait states are used
by the system, allowing for greater stability.
