Abstract: A server is provided. The server includes a Basic Input/Output System (BIOS) memory, a storage device, and a processing unit. The BIOS memory stores a BIOS code, and the BIOS code provides a BIOS setup menu and a saving option in the BIOS setup menu for setting information of a plurality of BIOS setup items. The processing unit is coupled to the BIOS memory and the storage device. The processing unit executes the BIOS code during a power-on self-test (POST) process of the server. When executing the saving option, the processing unit stores the setting information of the plurality of BIOS setup items into the BIOS memory and the storage device, and the processing unit also stores a designated file name into the storage device, the designated file name corresponding to the setting information of the plurality of BIOS setup items that is stored into the storage device.

Abstract: A method of power management includes steps of: in response to receiving from a server host a sleep command, an expander first outputting a predetermined register value to a processing unit in a normal state, and then switching to a power-saving state and outputting an interrupt signal to the processing unit; the processing unit determining whether both the predetermined register value and the interrupt signal are received; and when it is determined that both the predetermined register value and the interrupt signal have been received, the processing unit controlling a power supply to output standby electricity, making the expander and the processing unit operate based on the standby electricity.

Abstract: A server rack system includes a plurality of servers, a plurality of power supply units for supplying power to the servers, and a microcontroller electrically connected to the servers and the power supply units. The microcontroller is configured to determine a number of those of the servers that are currently in operation, compare the number with a critical value, determine whether each of the power supply units operates normally, and control at least one of the servers that are currently in operation to operate at a lower operating frequency when the number is greater than the critical value and at least one of the power supply units operates abnormally.

Abstract: A tool-free hard disk bracket includes a base having abase body with a guide groove, and an engaging member connected to the base body. A frame includes a first side arm movably engaging with the engaging member. A handgrip is rotatably connected to one end of the base body. An operating unit includes an operating member releasably engaging with the handgrip and having a rotating shaft portion inserted rotatably and movably into the guide groove. The operating member is operated to rotate and release engagement with the handgrip, and is further operated to move along the guide groove toward the engaging member to push the engaging member to pivot and release engagement with the first side arm.

Abstract: A server rack assembly includes a pair of mounting units each including a panel, an adjustment plate, and rails. The panel has a first panel flange to connect a front support post. The adjustment plate is movably connected to the panel for connecting a rear support post and is adjustable to suit varying distances between front and rear support posts. The rails are detachably mounted on the panel; a gap between two rails is adjustable to accommodate different server devices.

Abstract: A power supplying method for a computer system is proposed. The computer system includes a first computer node, a first power supply unit corresponding to the first computer node, a second computer node, a second power supply unit corresponding to the second computer node, and a connection module electrically connected to the computer nodes and the power supply units. The power supplying method includes: detecting, by the first computer node, whether the second power supply unit operates abnormally; and upon detecting at least that the second power supply unit operates abnormally, controlling, by the first computer node, the first power supply unit to provide electric power to the second computer node through the connection module.

Abstract: A cross authentication method includes steps of: a host central processing unit (CPU) module sending to a baseboard management controller (BIC) a request for BMC signature; the host CPU module receiving BMC signature data from the BMC; the host CPU module determining whether the received BMC signature data is authentic based on a BMC public key stored in the host CPU module; and the host CPU module allowing the BMC to access the host CPU module when it is determined that the BMC signature data is authentic.

Abstract: A method for recovering a basic input/output system (BIOS) image file of a computer system is provided. The method includes steps of: controlling a switch unit of the computer system to switch from a first state to a second state when the BIOS image file is to be updated; reading a current BIOS image file so as to store the same as a backup; controlling the switch unit to switch back to the first state; determining whether a command is received within a first predetermined time period when the BIOS image file is successfully updated to a new version of the BIOS image file; and when negative, controlling the switch unit to switch to the second state and writing the backup of the current version of the BIOS image file.
