Preferable, the invention provides a kind of diagnostic device of tool multiple interfaces, wherein, if the signal of the energization pins of the pci interface that detects is a high level, then judging the interface that diagnostic device is connected with mainboard is pci interface; If the signal of the energization pins of the LPC interface that detects is a high level, then judging the interface that diagnostic device is connected with mainboard is the LPC interface; Be high level if detect the signal of energization pins of energization pins and the LPC interface of pci interface, then select pci interface to carry out the signal transmission.
Again, the present invention also provides a kind of diagnostic method of tool multiple interfaces, can diagnose the mainboard with pci interface or LPC interface, and wherein, this method mainly may further comprise the steps:
A. begin;
B. detect diagnostic device is connected the energization pins of back pci interface or LPC interface with mainboard signal;
C. according to the state of the energization pins of pci interface or the LPC interface of detecting, judge that the interface that this diagnostic device is connected with mainboard is pci interface or LPC interface;
D. the interface that is connected with mainboard through diagnostic device, the startup self-detection code that produces when catching the mainboard startup self-detection;
E. the startup self-detection code of catching is deciphered;
F. show the startup self-detection code after decoding, judge for operating personnel whether mainboard goes wrong;
G. finish.
Preferable, the invention provides a kind of diagnostic method of tool multiple interfaces, wherein, among the step c, if the signal of the energization pins of the pci interface that detects is a high level, then judging the interface that diagnostic device is connected with mainboard is pci interface; If the signal of the energization pins of the LPC interface that detects is a high level, then judging the interface that diagnostic device is connected with mainboard is the LPC interface; Be high level if detect the signal of energization pins of energization pins and the LPC interface of pci interface, then select pci interface to carry out the signal transmission.
Compared to prior art; The invention provides a kind of diagnostic device and method thereof of tool multiple interfaces; Not only can diagnose the mainboard that possesses distinct interface; The startup self-detection code of a certain interface is caught and shown to the different interface that utilizes diagnostic device to be provided with, and goes wrong thereby person easy to use judges which part (like keyboard, mouse etc.) of mainboard.
