Introduction of BIOS 3-7
Method 1: Setup up the CPU for the lowest speed for its brand. Turn
the power supply off and change the CPU. Then turn the
system on again, and set up the CPU parameters through
CPU SOFT MENU.
Method 2: Try turning the system on a few times (3~4 times) and the
system will automatically use its standard parameters to
boot. You can then enter BIOS SETUP again and set
up the new parameters.
Method 3: Since you have to open the computer case when you
change the CPU, it could be a good idea to use the
CCMOS jumper to erase the parameters of the original
CPU and to enter BIOS Setup to set up CPU parameters
again.
Note : The increase by 2.5% of the CPU speed is not a standard
feature of this product. It is only for use by our
development department to verify that the CPU is able to
work normally when CPU speed, operating temperature
and power supply are 2.5% higher or lower than the
standard values. This is to guarantee product stability. We
require the manufacturer of the Clock Generator to meet
the demands of our development department and to add a
TURBO Frequency feature used for testing purposes by
our R&D department. Of course, you can use this feature
to test the stability of your own system, but after you have
tested the product, we recommend that you set it back to
its normal value in order to guarantee system stability.
CPU Power Plane:
In the previous chapter we explained that the 586 CPUs can be
divided into two types: single voltage and dual voltage. This option will
normally auto-detect the type of your CPU, so you don
’
t need to make any
changes.
ä
Single Voltage: Single voltage CPU
ä
Dual Voltage: Dual voltage CPU
ä
Set up the voltage via CPU Marking
