Abstract: A method for managing passwords for a BIOS and a BMC is implemented by a computer including a processor, a BMC, a platform controller hub (PCH), a first non-volatile memory and a second non-volatile memory. The BMC stores a BMC password, the first non-volatile memory stores a BIOS password, and the second non-volatile memory stores a first string and a second string. The method includes steps of: upon receiving a command for changing the BIOS password, the processor changing the BIOS password via the PCH according to the command; the processor changing the second string via the PCH to be the same as the BIOS password; the processor rebooting the computer; the BMC changing the first string via the PCH to be the same as the second string; and the BMC changing the BMC password to be the same as the first string.

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 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.
