Abstract: An apparatus for changing BIOS parameters via an exchange file, including a control unit, a microprocessor, a first memory, a second memory, a third memory and a keyboard. The method includes the steps of saving N parameter banks of BIOS in the third memory, forming the exchange file and performing a operation process via parameter banks, which including the steps of forming, writing, reading, revising and opening the exchange file, selecting one of parameter banks and performing corresponding operations according to the selected parameter bank.

Abstract: An apparatus for changing BIOS parameters via a hot key, including a control unit, a microprocessor, a first memory, a second memory, a third memory and a keyboard. The first memory saves BIOS code while the third memory saves N parameter banks of BIOS. When the apparatus performs a keyboard-scanning process during power-on, the apparatus determines whether at least one hot key is triggered. If the hot key is triggered, the apparatus selects one of the N parameter banks. Then the BIOS performs a corresponding operation based on the selected parameter bank. The invention provides a method for changing BIOS parameters via a hot key through the apparatus.
