Parameter setting (Chipset Features Setup), memory efficiency set option, video signal cache function (VIDEO automatically
BIOS Cacheable), power management (power management) setting etc..On the other hand, the present invention corresponds to setting for table
The form that is not limited to is set, any mode that set point correct can be differentiated according to system information should all be included in wherein.
Then, in step S216, the setting of processing unit 104 is default to read flag, to indicate that system reads default settings shelves
C2, for example, will be used to store the default memory bit for reading flag in non-volatility memorizer 102 is set as " 1 ", and in step
In rapid S218, system boots is returned to step S202 by processing unit 104, re-executes basic input output system 112.
Whereby, re-execute basic input output system 112 after system boots, processing unit 104 System self-test program initial stage then
The default flag that reads can be determined in step S204 to be set, and continue at step S208, read in modified default settings shelves
C2 removes default reading flag in step S210 to execute the subsequent action of basic input output system, to avoid past
Booting causes processing unit 104 to judge by accident afterwards.
In conclusion the present invention penetrate in System self-test program detecting system information come correspondingly modify input substantially it is defeated
