2. Position URM on the M/B next to the slot1 connector.
3. Push down retainer pin into respective fastener to secure URM onto the M/B.
4. Push CPU into URM to contact with slot1.
5. Make sure latching portion of CPU engaged with windows ledge of URM.
Installation for SECC II or SEPP CPU :
1. Same as step (1) of SECC.
2. Same as step (2) of SECC.
3. Same as step (3) of SECC.
4. Same as step (4) of SECC.
5. Snap in 2 clips into side windows of URM to secure SEPP CPU.
If there is a fan on the CPU, Please plug in the fan cable to the three pin fan connector on the motherboard
(FAN1).
2.2.2 For Socket 370 CPU
Before installing CPU, make sure the power is off. Locate the level bar on the PGA370 ZIF socket. Push level
bar away from the socket and pull upward 90 degrees. Insert the CPU into the socket. 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

3.2.1 Date
To assign the system date, the format is “mm.dd.yy”. The input range for the Month is 1-12. Range for Date is 1-
31. Range for Year is 1994-2079. System BIOS will calculate the day of the week automatically.
3.2.2 Time
To assign the system time, the format is “hh:mm:ss”. The setting is in military time. When entering 2:34pm enter
“14:34:00”.
3.2.3 Hard Disks Setting
The BIOS supports Dual-Channel PIO and PCI Bus Master IDE ports. Each port supports one master and one
slave hard drive. You can use <Enter> or <PageUp> or <PageDown> key to change hard drive type. Incorrect
setting may result in boot up error or system hang.
If your hard disk drive is not listed, you can select “Manual” mode to define your own drive manually. We
recommend that you select Type “AUTO” for all drives. The BIOS will auto-detect the hard disk drive and CD-
ROM drive at the POST stage.
If your hard disk drive is a SCSI device, please select “None” for your hard drive setting.

Select “Enabled” to enable CPU L2 Cache ECC Checking.
Select “Disabled” to disable CPU L2 Cache ECC Checking.
3.3.4 Processor Number Feature
This field will appear only when you are using a Pentium III processor. Each Pentium III processor comes with
an individual "processor serial number" which by default is activated. Therefore, when connected to the internet,
Pentium III processor transmits the serial number online making it possible to track your online activity. The field
provides you the option of disabling this function.
3.3.5 Quick Power On Self Test
Select “Enabled” to speed up time required to complete Power-On Self-Test.
3.3.6 First/Second/Third Boot Device & Boot Other Device
This option allows user to assign boot sequence of the system. Available options are Floppy, HDD, CD-ROM,
SCSI, LAN and LS120/ZIP. Set " Boot Other Device" to Enabled if you wish to boot from another device.
3.3.7 Swap Floppy Drive

3.3.9 Boot Up Numlock Status
The option allows the <NumLock> key to be activated after system boot up.
3.3.10 Gate A20 Option
This entry allows you to select how the gate A20 is handled. The gate A20 is a device used to address memory
above 1 Mbytes. Initially, the gate A20 was handled via a pin on the keyboard (Normal). Today, while keyboards
still provide this support, it is more common, and much faster, for the system chipset (Fast; default) to provide
support for gate A20.
3.3.11 Typematic Rate Setting
Select “Enabled” to configure “Typematic Rate” and “Typematic Delay” functions.
3.3.12 Typematic Rate
Use this option to set the rate at which a character keeps repeating while you hold down a key.

You can assign “Supervisor Password” and "User Password" in the main CMOS Setup Utility Screen.
3.3.15 OS Select for DRAM > 64MB
If you are using OS/2 operating system and installed memory is larger than 64MB. You need to have the setting
in the enable mode.
3.3.16 Report No FDD For WIN 95
While the FDD in “ STANDARD CMOS SETUP ” is set to NONE, set this option to No to release IRQ6 for
passing Win95 logo. This option is irrelevant under normal operation .
3.3.17 Video BIOS Shadow
Video shadow copies BIOS code from slower ROM to faster RAM. BIOS can then execute from RAM.
3.3.18 C8000-CBFFF /DC000-DFFFF Shadow

CMOS Setup Utility - Copyright ( C ) 1984 - 2000 Award Software
Advanced Chipset Features

3.4.1 Bank 0/1, 2/3, 4/5 DRAM Timing
DRAM timing is controlled by the DRAM timing registers. The timings programmed into this register are
dependent on the system design. The slower timing may be required in certain system designs to support loose
layouts or slower memory. Options are SDRAM 10ns, SDRAM 8ns, Normal, Medium, Fast, Turbo.
3.4.2 SDRAM Cycle Length
This item allows you to set the SDRAM Latency Timer. Options are 2, 3.
3.4.3 DRAM Clock
This item allows you to set the DRAM Clock. Options are Host CLK or HCLK-33M. Please set the item
according to the Host (CPU) Clock and DRAM Clock.
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 P2C/C2P Concurrency
When Disabled, CPU bus will be occupied during the entire PCI operation period.
3.4.6 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
