BIOS Setup Touch Panel PC

Advanced

▶Quiet Boot

This BIOS feature determines if the BIOS should hide the normal POST messages

with the motherboard or system manufacturer’s full-screen logo.
When it is enabled, the BIOS will display the full-screen logo during the boot-up

sequence, hiding normal POST messages.
When it is disabled, the BIOS will display the normal POST messages, instead

of the full-screen logo.
Please note that enabling this BIOS feature often adds 2-3 seconds of delay to

the booting sequence. This delay ensures that the logo is displayed for a sufcient
amount of time. Therefore, it is recommended that you disable this BIOS feature
for a faster boot-up time.

▶Bootup NumLock State

This setting is to set the Num Lock status when the system is powered on. Setting
to [On] will turn on the Num Lock key when the system is powered on. Setting to
[Off] will allow users to use the arrow keys on the numeric keypad.

▶Option ROM Messages

This item is used to determine the display mode when an optional ROM is ini­tialized during POST. When set to [Force BIOS], the display mode used by AMI
BIOS is used. Select [Keep Current] if you want to use the display mode of op­tional ROM.

3-6

▶CPU Conguration

▶Hyper-Threading

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 instruc-

tions 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.

▶Execute Disable Bit

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.

▶Limit CPUID Maximum

This 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.

3-7
