Motherboard 130 is electrically connected at storage element 120 and processing unit 110.Have a plurality of new-generation peripheral component interconnect express slots 131 in the motherboard 130, connect adapter 140 in order to connect new generation periphery.It can be the input and output (Input/Output) that show output, audio output or data that new periphery from generation to generation connects adapter 140 applied scopes.Storage element 120 is in order to Windows (Windows Operation System), hardware lookup table, hardware drive program and the target program of storage Microsoft (Microsoft).Processing unit 110 is in order to human window operating system, hardware drive program and target program.
Enumerate (enum) and can cause slot numbering and actual inconsistent problem for what avoid that prior art adopts, so the present invention has done following modification in the hardware drive program of Windows.For clearly demonstrating running of the present invention, also please refer to shown in Figure 2ly, it is an operation workflow synoptic diagram of the present invention.Driving method of the present invention comprises the following steps:
Step S210: start motherboard, the new generation periphery of obtaining on the motherboard to be connected through Basic Input or Output System (BIOS) connects adapter, and the hardware information that will new periphery from generation to generation connects adapter is stored in the hardware lookup table;
Step S220:, the hardware information that is write down in the hardware lookup table is added in the hardware drive program by Windows operation hardware loading procedure;
Step S230: operational objective program, target program are called corresponding new periphery from generation to generation through hardware drive program and the hardware information that is write down and are connected adapter;
Step S240: target program does not detect new generation periphery and connects adapter, and then target program sends error message to Windows; And
Step S250: target program detects new generation periphery and connects adapter, and then target program returns an output result after completion.
At first, in starting the process of (boot) motherboard 130, motherboard 130 can move respectively power-on self-test (Power on self test, POST) with Basic Input or Output System (BIOS) (Basic Input/Output System, BIOS).After the process of operation power-on self-test; Motherboard 130 can (for example: South Bridge chip group, new-generation peripheral component interconnect express or general-purpose serial bus (Universal Serial Bus, USB)) detect each item peripheral device of being connected one by one through Basic Input or Output System (BIOS).This is during one, Basic Input or Output System (BIOS) can with new-generation peripheral component interconnect express be recorded to the multiprocessor allocation list (MultiProcessor Configuration Table, MP_table) among.The multiprocessor allocation list is for proposing in the control standard of multiprocessor by Intel Company.The multiprocessor allocation list is in order to the running information of each item perimeter component of operating system is provided is connected for motherboard 130.So in the process of motherboard 130 starts, can new-generation peripheral component interconnect express be recorded to the multiprocessor allocation list, can call the relevant information that the multiprocessor allocation list is write down when making operating system.
Then, Basic Input or Output System (BIOS) obtains the new generation periphery that is connected on the motherboard 130 and connects adapter 140, and the hardware information that new periphery is from generation to generation connected adapter 140 is stored in the hardware lookup table.Wherein, hardware information comprises the slot numbering (slot number) and bus number (bus number) of the new-generation peripheral component interconnect express bus that new generation periphery connection adapter 140 is assigned.
Windows can carry out the detection and the loading of hardware during bringing into operation.So during this period, Windows of the present invention can move the hardware loading procedure, and the hardware information that is write down in the hardware lookup table is added in the hardware drive program.(Windows Driver Foundation WDF) carries out the processing of hardware loading procedure to utilize the window driver of Windows in the present invention.The standard entrance function of window driver is DriverEntry, in order to the object of responsible establishment and initialization WDFDRIVER, and in accomplishing the call back function of creating the connection of back increase new equipment.
