Abstract: A method of updating a firmware of a computer including a motherboard that has a BMC and a first CPLD, and a backplane that has a second CPLD having a flash memory. The method including steps of: the first CPLD changing a logical value of a signal when the first CPLD determines that a power of the computer is in a desired range; the BMC receiving the signal, and being initiated once the logical value of the signal has been changed; when the BMC is to update a firmware of the second CPLD, the BMC changing a logical value of a register of the first CPLD; and when the first CPLD determines that the logical value of the register has been changed, the first CPLD decoding and verifying a firmware code that is received from the BMC, and updating the firmware code thus decoded and verified to the flash memory.

Abstract: A method for reading information from multiple riser cards is implemented by a BMC module that includes an SMBus controller, where the riser cards are electrically connected to the SMBus controller. The method includes steps of: accessing a lookup table and a plurality of bus addresses; scanning a target address for communicating with a target card; determining whether a slave address has been received from the target card; when the BMC module determines that the slave address has been received from the target card, reading a memory of the target card according to a target reading spec to obtain identification information; determining whether the identification information conforms to an FRU header format; and when the BMC module determines that the identification information conforms to the FRU header format, reading the memory of the target card to obtain FRU information.

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 control system for a storage apparatus includes two input/output modules (IOMs), and two non-volatile memory (NVM) devices that are electrically connected to the IOMs, respectively, and that each store a firmware code. Each of the IOMs is configured to execute a firmware corresponding to the firmware code stored in the corresponding NVM device, and to enter an active mode or a passive mode after executing the firmware. The IOMs are configured such that when one IOM operating in the passive mode detects abnormal operation of the other IOM operating in the active mode, the one IOM sends, to the other IOM, the firmware code stored in the NVM device electrically connected to the one IOM, in order to update the firmware code in the NVM device electrically connected to the other IOM.

Abstract: A method includes steps of: assigning a value of a setting variable to a memory allocation variable; allocating address space to peripheral devices based on the memory allocation variable; determining whether allocated address space is sufficient; acquiring a system-wise greatest demand size value when allotted address space is insufficient; determining whether the memory allocation variable exceeds the system-wise greatest demand size value; updating the memory allocation variable to have a larger value when the memory allocation variable does not exceed the system-wise greatest demand size value; and assigning the value of the memory allocation variable to the setting variable when the memory allocation variable exceeds the system-wise greatest demand size value.

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.
