Installing Memory Modules

Locate the DIMM1 SO-DIMM slot. Align the notch on the DIMM with

1.
the key on the slot and insert the DIMM into the slot at 45-degree
angle.

Push the DIMM gently forwards until the slot levers click and lock

2.
the DIMM in place. Follow the same procedures to install the second
DIMM if necessary.

To uninstall the DIMM, ip the slot levers outwards and the DIMM will

3.
be released instantly.

Important

You can barely see the golden nger if the DIMM is properly inserted in
the DIMM slot.

BIOS Setup

▍

Max CPUID Value Limit

▶

The Max CPUID Value Limit BIOS feature allows you to circumvent
problems with older operating systems that do not support the Intel
Pentium 4 processor with Hyper-Threading Technology. When enabled,
the processor will limit the maximum CPUID input value to 03h when
queried, even if the processor supports a higher CPUID input value.
When disabled, the processor will return the actual maximum CPUID
input value of the processor when queried.

Execute Disable Bit Capability

▶

Intel’s Execute Disable Bit functionality can prevent certain classes of

malicious “buffer overow” attacks when combined with a supporting

operating system. This functionality allows the processor to classify
areas in memory by where application code can execute and where it
cannot. When a malicious worm attempts to insert code in the buffer,
the processor disables code execution, preventing damage or worm
propagation.

Hyper Threading Technology

▶

The processor uses Hyper Threading technology to increase transac­tion rates and reduces end-user response times. The technology treats
the two cores inside the processor as two logical processors that can
execute instructions simultaneously. In this way, the system perfor­mance is highly improved. If you disable the function, the processor will
use only one core to execute the instructions. Please disable this item
if your operating system doesn’t support HT Function, or unreliability
and instability may occur.

Intel(R) SpeedStep(tm) Tech

▶

EIST (Enhanced Intel SpeedStep Technology) allows the system to
dynamically adjust processor voltage and core frequency, which can
result in decreased average power consumption and decreased aver­age heat production.

Intel’s Dynamic Video Memory Technology (DVMT) allows the system to dy­namically allocate memory resources according to the demands of the sys-

tem at any point in time. The key idea in DVMT is to improve the efciency

of the memory allocated to either system or graphics processor.
It is recommended that you set this BIOS feature to DVMT Mode for maxi-

mum performance. Setting it to DVMT Mode ensures that system memory
is dynamically allocated for optimal balance between graphics and system
performance.

DVMT/FIXED Memory

When set to DVMT/FIXED Mode, the graphics driver will allocate a

Perform keyboard controller BAT test. Check if waking up from
power management suspend state. Save power-on CPUID value
in scratch CMOS.

Go to at mode with 4GB limit and GA20 enabled. Verify the boot­block checksum.

Disable CACHE before memory detection. Execute full memory siz-

stack.

Bootblock code is copied from ROM to lower system memory and
control is given to it. BIOS now executes out of RAM.

Both key sequence and OEM specic method is checked to deter­mine if BIOS recovery is forced. Main BIOS checksum is tested. If

BIOS recovery is necessary, control ows to checkpoint E0. See

Bootblock Recovery Code Checkpoints section of document for
more information.

interface module is moved to system memory and control is given to

it. Determine whether to execute serial ash.
