Abstract: A firmware updating method, implemented in a server and a client computer. The client computer comprises an application and at least a peripheral device comprising a first firmware program and identification information. The server stores at least a second firmware program. An auto-execution program is initiated through a shortcut on a menu of the application. The auto-execution program directs the client computer to automatically connect to the server, determine the identification information of the peripheral device, determine whether the second firmware version is newer than the first firmware version, display a list indicating the second firmware program if the second firmware version is newer than the first firmware version, download the second firmware program from the server to the client computer when the second firmware program is selected, and replace the first firmware program with the second firmware program.
