CPU Frequency
This parameter displays your CPU’s speed and bus frequency. Selecting
this option displays the following screen:
Parameter Description Option
Bus Frequency The bus frequency refers to the speed by
which data is transferred between internal
computer components and the CPU or the
main memory of the CPU. A fast bus
allows data to be transferred faster, which
makes applications run faster.
Processor
Speed The processor speed is the speed at which a
microprocessor executes instructions.
Clock speeds are expressed in megahertz
(MHz), with 1 MHz being equal to 1 million
cycles per second. The faster the clock, the
more instructions the CPU can execute per
second.
Single
Processor MP
Table Enabling this parameter allows BIOS to
create a multiprocessor (MP) table for
Windows NT use. In a single-processor
system running Windows NT, you may
disable this parameter to enhance system
performance. If you install another CPU
for a dual system, enable this parameter
then re-install Windows NT.
In cases when this parameter is enabled
before installing Windows NT in a single-
processor system, you may upgrade to a
multiprocessor system without reinstalling
Windows NT.
