Cine porneste placa de baza.

Recommended Posts

Guest costinlipan

Imi poate spune cineva ce se intampla in mare intr-o placa de baza? Ma intereseaza modul de functionare. De cateva ore caut pe internet si gasesc numai prostii sau lucruri "de suprafata".Ma intereseaza ce se intampla din momentul in care este introdusa sursa de alimentare in priza (si cei 5 volti de standby intra in placa), pana la momentul in care sunt initializate componentele (porneste BIOSul).Cu alte cuvinte: cine porneste placa de baza?Multumesc mult!

"Pornirea" placii de baza la apasarea push-button-ului de power, aflat pe panoul frontal al PC-ului, este realizata de un circuit integrat cu 128 pini, aflat pe placa de baza, numit "super IO"(super input output).Este acel integrat SMD cu pini pe toate patru laturile, pe care scrie ITE sau SMSC.

Tot acest cip contine controller-ul de floppy, tastatura, mouse, la el se duc senzorii de temperatura, etc.
