Abstract

A server device includes a memory module and a chip module. The memory module is used for storing at least one configuration bit and various configuration files. When the servo device is in a power-on mode and the chip module detects that the first BIOS configuration file temporarily stored previously cannot be read, the chip module reads the configuration bit. The chip module takes one of the multiple configuration files as one of the first BIOS configuration file and a target configuration file according to the configuration bit and a configuration selection command. The chip module determines whether to receive a setting command, and the setting command is used to determine whether to enter an adjustment mode. When it is determined not to enter the adjustment mode, the chip module executes the boot procedure according to the stored first BIOS configuration file.

Then, proceed to sub-step (B7).

(B7) The display 4 automatically displays a user prompt screen, wherein the user prompt screen displays a set of user shortcut keys corresponding to a configuration selection command to prompt the user to choose to enter a user configuration selection mode. Then, proceed to sub-step (B8).

(B8) The chip module 3 determines whether it receives a configuration selection command to determine whether to enter the user configuration selection mode. If yes, go to sub-step (B9), if not, go to step (C1).

After that, proceed to step (F1).

(C1) The processor 31 of the chip module 3 determines whether to receive a setting command. Whether the setting command is received or not is used to decide whether to switch to an adjustment mode or to maintain a default non-adjustment mode, that is, The processor 31 of the chip module 3 determines whether the user chooses to switch to the adjustment mode to enter the BIOS SETUP interface for parameter adjustment based on whether the setting command is received. If not, then proceed to step (E). If yes, then proceed to step (E). Step (D1). To further explain, when the server starts up, the timer will be started, and then the servo device will complete the startup stage and allow the user to enter the shortcut key to switch to the adjustment mode. Until the timer time is up, no data from the user has been received. When the setting command is entered, the servo device will determine not to enter the adjustment mode and load the first BIOS configuration file stored in the CMOS.

(E) When in the default non-adjusting mode (if the servo device does not receive the setting command after being turned on, the processor 31 will remain in the non-adjusting mode), the processor 31 of the chip module 3 uses CMOS Continue to execute the BIOS program in the currently stored first BIOS configuration file (saved in step A6, step B5 or B6) to continue the boot process, that is, do not restart the computer system running on the server device/do not restart The processor 31 is initialized, and the processor 31 directly uses the first BIOS configuration file currently stored in the CMOS to continue the boot process, so as to guide the processor 31 to load and execute an operating system after completing the boot process.
