Abstract:
1. A computer system comprising: a central processing unit (CPU); a basic input/output system (BIOS) coupled to the CPU, wherein the BIOS includes a testing function for executing a memory test procedure and tunes a memory parameter value according to the testing result of the memory test procedure; and an embedded controller coupled to the BIOS for accumulating a counting value and sending a reset signal to reboot the computer system; and a memory connected to the CPU; wherein the BIOS retrieves the counting value from the embedded controller to import the memory parameter value corresponding to the counting value and executes the memory test procedure; if the memory test procedure succeeds, the BIOS stores the memory parameter value, and if the memory test procedure fails, the embedded controller accumulates the counting value and sends the reset signal to reboot the computer system, thereby making the BIOS reload another memory parameter value corresponding to the accumulated counting value and re-execute the memory test procedure.
