Introduction of BIOS 3-5
But when you boot the computer, the mainboard will automatically detect
the CPU brand and type.
CPU Operating Speed:
This option sets the CPU speed. Different CPU brands use different
techniques to indicate the CPU speed. For example, AMD and Cyrix use
P-Rating.
In this field, the CPU speed is indicated like this: CPU speed (external
clock x multiplier factor)
Select the CPU speed according the type and the speed of your CPU.
【Note 1】For Intel Pentium CPUs, you can choose the following settings:
ä 75 (50x1.5) ä 90 (60x1.5)
ä 100 (66x1.5) ä 120 (60x2)
ä 133 (66x2) ä 150 (60x2.5)
ä 166 (66x2.5) ä 200 (66x3)
【Note 2】For AMD-K5 CPUs from AMD, you can choose the
following P-Ratings:
ä PR75 (50x1.5) ä PR90 (60x1.5)
ä PR100 (66x1.5) ä PR120 (60x1.5)
ä PR133 (66x1.5) ä PR166 (66x1.75)
【Note 3】For Cyrix 6x86 and 6x86L CPUs, you can choose the
following P-Ratings:
ä PR120+ (50x2) ä PR133+ (55x2)
ä PR150+ (60x2) ä PR166+ (66x2)
ä PR200+ (75x2)
【Note 4】User define external clock and multiplier factor:
ä User Define
/ External Clock:
ä 50MHz ä 55MHz
ä 60MHz ä 66MHz
ä 75MHz ä 83MHz(If hardware
supports.)
/ Multiplier Factor:
You can choose the following multiplier factors:
ä 1.5 ä 1.75
ä 2.0 ä 2.5
ä 3.0 ä 3.5
