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
¤ When the CPU is single voltage, the following options will be displayed to
set up the voltage:
/ Plane voltage:
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
