Bios setting method

A basic input output system (BIOS) setting method, which is applicable to a BIOS setting procedure of a data processing unit having a display unit and an input unit, the BIOS setting method comprising the following steps of:

• (1) after the data processing unit is turned on and while a power on self test (POST) procedure of the BIOS is being executed, displaying messages of a first function key and a second function key on the display unit, the first function key being for entering a first BIOS setting mode, the second function key being for entering a second BIOS setting mode;
• (2) determining whether the first function key or the second function key is pressed via the input unit, and proceeding to step (3) if the first function key is pressed, to step (4) if the second function key is pressed, or continuing executing the POST if none of the first function key and the second function key is pressed;
• (3) entering the first BIOS setting mode from the POST procedure, and determining whether any setting contents of the first BIOS setting mode are revised and saved in the data processing unit and proceeding to step (5) if some of the setting contents of the first BIOS setting mode are revised and saved in the data processing unit or skipping the first BIOS setting mode and continuing executing the POST procedure if none of the setting contents of the first BIOS setting mode are revised or saved in the data processing unit;
• (4) entering the second BIOS setting mode from the POST procedure, and determining whether any setting contents of the second BIOS setting mode are revised and saved in the data processing unit and proceeding to step (6) if none of the setting contents of the second BIOS setting mode are revised or saved in the data processing unit or skipping the second BIOS setting mode and continuing executing the POST procedure if some of the setting contents of the second BIOS setting mode are revised and saved in the data processing unit;
• (5) continuing executing the corresponding POST procedure based on the revised setting contents of the first BIOS setting mode;
• and
• (6) commanding the data processing unit to restart, and returning to step (1).
