Abstract: An exemplary network system includes a remote computer and a network server. The remote computer includes a baseboard management controller (BMC), a south bridge chipset, a power button, and a switching circuit. The switching circuit has a control terminal connected to an output of the BMC, a power terminal connected to a power supply, and also connected to a SB_PWRBTN pin of the south bridge chipset, and a ground terminal connected to ground via the power button. The network server is connected to an input of the BMC of the remote computer, the network server outputs a control signal for forbidding activating the remote computer, the BMC receives the control signal and outputs a low level voltage signal to turn off the transistor, and the remote computer can not be activated.

Abstract: A motherboard comprises a first unit which includes most components that are common in a group of motherboards which have a same chip set, a second unit which includes components that are different in the group of motherboards, and a BIOS Bin file which is loaded in the first unit. The BIOS Bin file comprises a share module, a loading module unit which includes a plurality of loading modules each corresponding to one type of motherboard, and a startup module which identifies the type of the motherboard according to a voltage of pre-selected GPIO Pins, and reads one of the loading modules corresponding to that type of motherboard to identify and initiate the second unit, and reads the share module to identify and initiate the first unit.

Abstract: An exemplary method for generating a BOM file is disclosed. The method includes the steps of: extracting data on components of a circuit design diagram of a motherboard, and storing the data in an spreadsheet as a non-standardized original BOM file; determining whether the data meet requirements corresponding to designing standards of the motherboard by checking the data of the non-standardized original BOM file; classifying the data into lists according to predefined manufacturing procedures; and automatically generating a standardized BOM file according to the corresponding lists. A related system is also disclosed.

Abstract: A system is provided for extracting material changes in different design diagrams of a motherboard. The system includes: an extracting module for extracting a first raw BOM from a first circuit design diagram of the motherboard, and for extracting a second raw BOM from a second circuit design diagram of the motherboard, wherein the second circuit design diagram is partially identical to the first circuit design diagram; a converting module for converting the first raw BOM to a first standard BOM, and for converting the second raw BOM to a second standard BOM; a integrity checking module for determining whether data in the two standard BOMs are error free; and an comparing module for comparing the two standard BOMs to extract material changes. A related method is also disclosed.

Abstract: A method for starting an operating system rapidly by a hotkey includes the steps of: setting a hotkey for each operating system; executing a BIOS power on self test program; determining whether any hotkey has been pressed during execution of the power on self test program; activating a disk partition section which stores an operating system corresponding to a hotkey if the hotkey has been pressed; loading a master boot record; starting the operating system stored in the activated disk partition section.
