Pilot lamp LED is used for+indication of 5VSB power supply, explanation computing machine on power supply when LED light is bright.
Remove pilot lamp LED and wireless receiving module 18 automatic networks among Fig. 3 and switch pci card and guide to register face, wireless transmission circuit 10 itself just is installed on the mouse, and all the other all are installed in network and switch on the pci card.
15,16,17,18,19,20,22,23,32,33,40,41, R5, R6, R7, R8, C1, LED working power provide by computing machine standby power+5VSB label is among Fig. 3:, label 10 is provided by power supply on the mouse, and all the other labels need working power to be provided by computer power supply+5V.
As shown in Figure 5, expansion ROM chip 34 has the control program that network switches pci card, by the condition code program that reads I/O IO interface 23, network switching judging program, floppy disk, CD, USB memory device trace routine and attention program, the Starting mode determining program, the internal memory clear program is formed I/O IO interface 23 clear " 0 " programs.
The condition code program that reads I/O IO interface 23 is used to read network switching signal and Starting mode condition code.
Network switching judging program is used for the network switching signal of judging characteristic sign indicating number, differentiating the current computer startup is that network switches, and still normal the startup is that next step floppy disk, CD, USB memory device trace routine are carried out in the network switching, (the normal startup) do not change and finishes.
Whether detection floppy drive, CD-ROM drive, USB interface had memory bank to exist when floppy disk, CD, USB memory device trace routine were used for the network switching, have memory bank to exist and carry out attention program prompting user taking-up, no memory bank exists carries out next step Starting mode determining program.
The Starting mode determining program is used for the Starting mode of judging characteristic sign indicating number, be to restart the network that carries out to switch, still the network that carries out of starting shooting switches, be to restart the network that carries out to switch next step internal memory clear program of execution, arrive I/O IO interface 23 clear " 0 " programs again,, do not change I/O IO interface 23 clear " 0 " programs.
I/O IO interface 23 clear " 0 " programs are used to make I/O IO interface 23 clear " 0 ", be next computer starting service, make computing machine like this when not carrying out network switching startup computing machine, expansion ROM chip 34 program bodies are only carried out condition code program and the network switching judging program that reads I/O IO interface 23, improve starting up speed and easy to use.
