Detailed description of the invention
In correlation technique, electronic equipment is found normal boot-strap or the mode of reason do not started shooting to generally comprise
Following two:
1) find the electronic equipment cannot normal boot-strap or do not start shooting by main board diagnostic (Debug) card
Reason；
Fig. 1-1 is the connection diagram using Debug card diagnosis PC fault in correlation technique, such as Fig. 1-1
Shown in, the mainboard 10 of PC includes embedded controller (Embeded Controller, EC chip) 12
With chipset 11, wherein the function of EC chip mainly includes three aspects: first, the sequential control of switching on and shutting down
System；Second, hardware Gernral Check-up and system health, such as the rotating speed of fan is controlled, and to being
The control of system temperature, the 3rd, support input/output (I/O) equipment, serial paralled interface etc..Current Debug
Card is essentially all low pin count (LPC, Low Pin Count) interface, cannot normal boot-strap analyzing
Or do not start shooting basic reason time, need Debug card by pin (header) and cable (cable)
It is connected on the LPC interface of chipset on mainboard 10.Debug card is to utilize basic input and output in mainboard
The testing result of system (BIOS, Basic Input Output System) built in self testing program, passes through code
Show one by one, in conjunction with code implication zoom table, just can know computer glitch place soon.Especially exist
When personal computer (PC) machine can not guide operating system, blank screen, loudspeaker not to cry, main board failure is used to examine
Disconnected card will be more convenient, get twice the result with half the effort.
The flow process using Debug card diagnosis PC fault includes: step a, takes cabinet apart；Step b, passes through
Debug card 21 is connected on the LPC interface of chipset 11 on mainboard 10 by pin and cable；Step c,
The testing result of BIOS built in self testing program is transferred to by the chipset 11 on mainboard 10 by LPC interface
Debug card 21；Step d, Debug card 21 is that the detection utilizing BIOS built in self testing program in mainboard is tied
Really, by code, the failure problems of PC is shown；Step e, maintainer combines the quick checking of code implication
Table, by the guilty culprit understanding PC of tabling look-up.
2) by basic input output system recovery process (BIOS Recovery) find electronic equipment without
Method normal boot-strap or the reason do not started shooting；
This BIOS recovery process comprises the following steps: step a, takes cabinet apart；Step b, finds BIOS
The jump cap of module (boot block) is started in system；Step c, wire jumper short circuit；Step d, plugs USB flash disk
(U Disk), in USB flash disk, storage has BIOS；Step e, runs the startup module in BIOS, makes PC enter
Enter DOS system, then carry out BIOS recovery process.
Above-mentioned process fault detection is required for opening computer cabinet just can be carried out, from the above it can be seen that
Operate complex steps, especially for all-in-one (AIO, All In One), after sale and maintainer behaviour
Make to get up extremely inconvenience, waste time and energy, thus add after cost.
As it was previously stated, when using failure diagnosis card for main board, need to be connected to by electronic equipment on LPC interface,
This is accomplished by taking cabinet apart；And BIOS recovery process needs to start wire jumper short circuit in the jump cap of module,
Therefore it is also required to take cabinet apart.Based on problem present in above-mentioned background technology, the following enforcement of the present invention
Example will provide a kind of diagnostic device based on USB (universal serial bus) (USB, Universal Serial Bus),
This equipment is capable of the function completing above-mentioned failure diagnosis card for main board in the case of being not switched on cabinet with basic
The function of input-output system recovery process.This is because USB interface be on electronic equipment especially PC,
A kind of external interface indispensable on notebook computer and all-in-one, using this USB interface when, it is not necessary to
Take the cabinet of PC apart, therefore use more convenient.
