1. Pull up the CPU socket lever and up to
90-degree angle.
2. Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper interface.
Match Pin 1 and cut edge. Then insert the
CPU into the socket.
3. Press down the CPU socket lever and finish
CPU installation.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge
well, it may damage the CPU.

Voltage.
Setting CPU Frequency
The CPU Frequency will be automatically detected. It is not necessary to set CPU
Frequency.
Core Frequency = CPU FSB Clock * CPU Ratio

You can clear CMOS to restore system default setting. To
clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin 1 & pin 2.
5. Connect ATX power cable back to connector PWR2.

When the PC tries to boot and finds the BIOS code corrupted, the boot block will
try to recover the BIOS code. You may have to change JP15 setting to enable this
capability. The boot block will load the BIOS code and then when you next reboot,
the regular BIOS code should be in place and the problem resolved.
The onboard I/O devices are PS/2 Keyboard, PS/2 Mouse, COM1, VGA, Printer and
USB1.1. The view angle of drawing shown here is from the back panel of the housing.

A ZCR card is a PCI card that allows a RAID card to use the onboard SCSI chip, thus
lowering cost of RAID solution.
A "Zero-channel" RAID adapter is a PCI RAID
controller that doesn't have any SCSI channels on board. Instead, it is designed to
use the on-board SCSI channels of the motherboard to implement a cost-effective
Hardware RAID solution. Please be informed that only the first PCI slot supports
ZCR function. (AX4S Plus-U only)
