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 JP6 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
¤ When the CPU is single voltage, the following options will be displayed
to set up the voltage:
/ Plane voltage:
ä 3.60v ¡G Reserved
ä 3.52v ¡G For Intel VRE standard CPUs and AMK-K5 or Cyrix 8x86
ä 3.38v ¡G For Intel STD and VR standards CPUs
