The motherboard provides a Single Edge Contact(SEC)slot for a Pentium II
processor packaged in an SEC cartridge. Follow these steps to install
Pentium II CPU:

Mount the Universal Retention Mechanism (URM) & Insert the Pentium II
CPU: ( The illustration is just for reference )

This URM was designed to accommodate 3 types of CPU Form Factor.
( SECC, SECCII & SEPP ). For Example : Pentium II & Celeron family.

Note : Please put a soft pad under M/B before the installation of URM.

Installation for SECC CPU :

1. Leave space below each mounting hole for the fastener to
protrude through the hole.

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.

This field allows you to use a Plug-and-Play (PnP) operating system.

Please set it as No if the operating system has no PnP function or to avoid
reassigning the IRQs by the operating system.

3.6.2 Resources Controlled By

Default setting is "Auto". This setting allows the BIOS to self detect setting and Plug­and-Play devices during start up. The user can select and configure IRQs under
"Manual" mode.

3.6.3 Reset Configuration Data

In case a conflict occurs after you assign the IRQs or after you configure your system,
you can enable this function to allow your system to automatically reset your
configuration and reassign the IRQs, DMAs, and I/O address.

3.6.4 IRQ-xx assigned to

If your ISA card is not PnP compatible and requires a special IRQ to support its
function, set the selected IRQ-x assigned to :Legacy ISA. This setting informs the
PnP BIOS to reserve the selected IRQ for the installed legacy ISA card.

3.6.5 DMA-x assigned to

If your ISA card is not PnP compatible and requires a special DMA channel to support
its function, set the selected DMA channel to Legacy ISA. This setting informs the
PnP BIOS to reserve the selected DMA channel for the installed legacy ISA card.

3.6.6 PCI IDE IRQ Map To

Some old PCI IDE add-on cards are not fully PnP compatible. These cards require
you to specify the slot in use to allow the BIOS to properly configure the PnP
resources.

3.6.7 Primary/Secondary IDE INT#

These two items, in conjunction with item PCI IDE IRQ Map To, specify the IRQ
routing of the primary or secondary channel of the PCI IDE add-on card.

3.6.8 Used MEM base addr

This item, in conjunction with the Used MEM Length, lets you set a memory space for
non-PnP compatible ISA card.

3.6.9 Assign IRQ For USB

Default is Enabled. You can disable this item when you do not attach any
USB devices on board and need extra IRQ for other device. The yellow
exclamation mark will be shown in System/Device Manager under Windows
95/98 if you disable this item. This is a normal status.

3.7 Integrated Peripherals

You can control Input and Output functions from this screen.

ROM PCI / ISA BIOS (XXXXXXXX)

INTEGRATED PERIPHERALS

AWARD SOFTWARE, INC.

3.7.1 IDE HDD Block Mode

This feature enhances disk performance by allowing multi-sector data transfers and
eliminates the interrupt handling time for each sector.

3.7.2 IDE Primary & Secondary Master/Slave PIO

These four PIO fields let you set a PIO mode (0-4) for each of four IDE devices.
When under "Auto" mode, the system automatically set the best mode for each
device

3.7.3 IDE Primary & Secondary Master/Slave UDMA

When set to "Auto" mode, the system will detect if the hard drive supports Ultra DMA
mode.

3.7.4 On-Chip primary/Secondary PCI IDE

Select "Enabled" to activate each on-board IDE channel separately, Select "Disabled",
if you install an add-on IDE Control card

3.7.5 USB Keyboard Support

This item lets you enable or disable the USB keyboard driver within the onboard
BIOS.

3.7.6 Init Display First

This item lets the system to detect AGP or PCI-Slot first when boot-up.

3.7.7 Onboard FDC Controller

Select "Enabled" to activate the on-board FDC
Select "Disabled" to activate an add-on FDC

3.7.8 Onboard UART Port 1 & 2

Select an address and corresponding interrupt for the first/second serial port. The
default value for the first serial port is "3F8/IRQ4" and the second serial port is
"2F8/IRQ3".

3.7.9 UART2 Mode

Select to activate the Infrared transfer function.

3.7.10 Onboard Parallel Port

Select address and interrupt for the Parallel port.

3.7.11 Parallel Port Mode

Select an operating mode for the parallel port. Mode options are SPP, EPP1.7,
ECPEPP1.7, EPP1.9, ECP and ECPEPP1.9.

3.7.12 ECP Mode Use DMA

Select a DMA channel if parallel port is set as "ECP" , "ECPEPP1.7" or "
ECPEPP1.9".

3.8 Load BIOS Defaults

This loads the standard BIOS default values. To select, highlight it and press
the <Enter> key. Then press the <Y> and <Enter> keys to confirm. Otherwise,
press the <N> key to cancel.

3.9 Load Setup Defaults

This feature loads the setup default values from BIOS default table. To select,
highlight it and press the <nter> key. Then press the <Y> and <Enter> keys
to confirm. Otherwise, press the <N> key to cancel.

3.10 Supervisor/User Password

You can assign, modify, or cancel password settings. To modify, highlight
"Supervisor Password" or "User Password" and press the <Enter> key. The
screen will prompt you ("Enter Password:"). Enter your password. The
maximum size of the password is 8 characters. System will prompt you to
reenter the password to verify. Remember the passwords are case sensitive.

If you want to remove the passwords, either delete passwords or press
<Enter> when prompting for new password.

If you want it to require password upon initial system startup and upon
entering the CMOS Setup Utility, you will need to change the selection of the
(Security Option) under (BIOS FEATURES SETUP) to "System".

If the setting is "Setup", the system will only require the password you
activate CMOS Setup Utility.

3.11 IDE HDD Auto Detection

If your system has an IDE hard drive, you can use this function to detect its
parameters and enter them into the Standard CMOS Setup automatically.

This routine only detects one set of parameters. If your hard disk is formatted
using different parameters than those detected, you have to enter the
parameters manually. If the parameters listed do not match the ones used to
format the disk, the information on that disk will not be accessible. If the auto­detected parameters displayed do not match those that are used for your
drive, ignore them. Type N to reject the values and enter the correct ones
manually from the Standard CMOS Setup screen.

3.12 Exit CMOS Setup Utility

Press the <F10> key to save the setup and exit. Press <ESC> key to exit
without saving. Either saving or not saving modifications, screen will prompt
user to confirm, and system will reboot on exit.
