Jumpers

The mainboard provides jumpers for setting the mainboard’s functions. This
section will explain how to change settings for your mainboard’s functions
through the use of the jumpers.

Clear CMOS Jumper: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has an onboard
battery power supply. The long-life battery has a lifetime of at least 5 years.
If you want to clear the system configuration data from the CMOS RAM, use
the CLEAR_CMOS (Clear CMOS jumper). Follow the instructions below to
clear the data:

You can clear the CMOS by shorting 1-2 pin while
the system is off. Then return it to the 2-3 pin

WARNING!

position. Avoid clearing the CMOS while the
system is on; this will damage the mainboard.

RCA Video or S/PDIF Select: SPDIF_SEL

Users can select either RCA Video or S/PDIF as the enabled function on the
dual-purpose port. For TV-out composite function, please short 1-2. For RCA
Video, short 3-4 (default).

PCI Interrupt Request Routing

The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor. The “PCI & LAN” IRQ pins are typically connected to the
PCI bus INT A# ~ INT D# pins as follows:

Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT B# INT C# INT D# INT A#
IEEE1394 INT B#

BIOS Setup

Frequency/Voltage Control

DRAM Clock

The chipset supports synchronous and asynchronous mode between host clock
and DRAM clock frequency. Settings: By SPD, 100MHz and 133MHz.

DRAM Timing

This setting determines whether DRAM timing is configured by reading the
contents of the SPD (Serial Presence Detect) EPROM on the DRAM module.
Selecting Yes makes SDRAM Cycle Length and Bank Interleave automatically
determined by BIOS according to the configurations on the SPD. Settings: Manual
and By SPD.

SDRAM CAS Latency

Set the time between SDRAM read command and when the data actually be­comes available. Settings: 2 and 2.5.

Bank Interleave

Set the interleave mode of the SDRAM interface. Interleaving allows banks of
SDRAM to alternate their refresh and access cycles. One bank will undergo its
refresh cycle while another is being accessed. This improves performance of the
SDRAM by masking the refresh time of each bank. Settings: Disabled, 2 Bank
and 4 Bank.

Precharge to Active (Trp)

Set the time from DRAM precharge to active state. Settings: 2T and 3T.

3-25

Chapter 3

Active to Precharge (Tras)

Set the time from active back to precharge state. Settings: 5T and 6T.

Active to CMD (Trcd)

Set the time from active state to command state. Settings: 2T and 3T.

DRAM Command Rate

This setting controls the DRAM command rate. Selecting 1T allows DRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting 2T makes DRAM
signal controller run at 2T rate. 1T is faster than 2T. Settings: 2T Command and
1T Command.

DRAM Burst Len

This setting allows you to set the size for DRAM Burst-Length. The bigger the
size, the faster the system addresses memory. Settings: 4 and 8.

DRAM Voltage

This setting allows you to set the appropriate DRAM voltage. Setting
options: 2.5V, 2.6V, 2.7V and 2.8V

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the spikes
of the pulses are reduced to flatter curves. If you do not have any EMI problems,
leave the setting at Disabled for optimal system stability and performance. But if
you are plagued by EMI, setting to Enabled for EMI reduction. Remember to
disable Spread Spectrum if you are overclocking because even a 0.25% jitter can
introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which
may just cause your overclocked processor to lock up.

Settings: Disabled, -0.

enter the password. A message will show up confirming that the pass­word will be disabled. Once the password is disabled, the system will
boot and you can enter Setup without entering any password.

When a password has been set, you will be prompted to enter it every
time you try to enter Setup. This prevents an unauthorized person from
changing any part of your system configuration.

Additionally, when a password is enabled, you can also have BIOS to
request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the
password prompt is required is the Security Option of the Advanced
BIOS Features menu. If the Security Option is set to System, the password
is required both at boot and at entry to Setup. If set to Setup, password
prompt only occurs when trying to enter Setup.
