Introduction of BIOS 3-5
äDisable:CPU external clock is operating
within the normal limits.
äEnable: CPU external clock is operating
within the limits of the Turbo mode.
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.
Solution in case of initializing problem due to invalid CPU setup:
If the CPU parameters are not setup properly , it might be impossible to
power on and initialize system. In such case:
1. Turn the system on and off a few times(3~4 times). The system will
automatically use its standard parameters to boot.
2. OR: Hold Insert key and turn POWER ON. The system will automatically
use its standard parameters to boot. You can then enter BIOS SETUP
again and set up the new parameters.
When you change your CPU:
This mainboard has been designed in such a way that you can turn the system
on after having inserted the CPU in the socket without having to configure any
jumpers or DIP switches. But if you change your CPU, normally, you just have to
turn off the power supply, change the CPU and then, set up the CPU parameters
through CPU SOFT MENU
™
II However, if the new CPU is slower than the old
one, we offer you two methods to successfully complete the CPU change
operation.
