Kuyini bios

Abanye abanikazi ikhompyutha, muva nje kuphela yaqala ukuhlola umhlaba ubuchwepheshe bama-computer, ungase ungaluboni ngisho nalapho usola ukuthi ngaphezu yesistimu yokusebenza kanye nezinhlelo ezihlukahlukene ngawo ungasebenza njengenjwayelo (chofoza kabili - ukufakwa - ukuqala), kukhona yonke ndawo ikhodi isofthiwe kancane etholakalayo. Kuyinto Yebo, mayelana BIOS (BIOS).

Ake sibone ukuthi bios. Ukuze ngikwenze kucace kakhudlwana, asiqale isibonelo. Cabanga kwikhompuyutha abstract lapho ufuna ukulayisha windose yesistimu yokusebenza. Faka ezifanele intambo yamandla ku esitolo esidayisa futhi ibenze uhlelo iyunithi inkinobho amandla futhi ... lutho kwenzeka, ngoba uma asazi ukuthi bios ke ebhodini yakhe noma cha. Cabanga indlela computer kungaba "ukwazi" ukuthi udinga ukuqala ukulanda it kusukela hard drive, kanye ethize? Phela, ungakwazi Boot kusuka flash drive, i-CD, ngisho kunethiwekhi zendawo. Kungani idrayivu kanzima? Ngakho-ke, kuthathwa ngokuthi endaweni ethile kukhona indlela isofthiwe kwikhompyutha, ikuvumela ukuba ucacise lapho ukuze uqale ukulanda.

Ukuqagela ilungile! Lena ngempela. Nanku umbuzo lokho bios. Kunoma iyiphi umbadlana kuyinto chip ekhethekile, okuyinto eye embonini langena uhlelo encane control. imisebenzi yayo, yebo, abutholakali kudivayisi eyodwa kukho ebhuthini.

umsebenzi Computer simiswe ngalendlela lelandzelako: zonke izingxenye ithola amandla, abalawuli zabo yangaphakathi enze ukuhlolwa self-kungakanani abakwaziyo kanye nokuhlola, uma konke kuhambe kahle, ufake ithenda kancane. Ngokulandelayo, ulawulo wadlulela firmware, ise-chip BIOS, ke aqalaze amathaya izingxenye uxhumekile futhi poll isimo sabo amarejista. Khona-ke, i-BIOS ilungiselela IRQ futhi DMA iziteshi zonke izingxenye axhunyiwe. Futhi ngokuhambisana SPD embukisweni ukubambezeleka RAM amamojuli kanye chipset. By the way, CAS angasethwa kuphela kulesi sigaba, kuze kube yilapho imemori ayisetshenziselwa. manje kuyacaca ukuthi lokhu bios?

Uma i-algorithm inkinga uphazamiseka futhi umyalezo wephutha (kungaba umbhalo kwesikrini noma code piping uhlelo Dynamics).

Umsebenzisi kungaba angenele BIOS ukusebenza, okwenza izinguquko: Ukukhethwa ukubambezeleka inkumbulo, ukwenqatshelwa ukudla kulesi / ukusebenza eziningi ezifakiwe, inkomba oda amadivayisi zokuvota ukulayisha uhlelo lokusebenza. Izinguquko zigcinwa ngenxa amabhethri duty voltage esisogwini ebhodini. Kumila kuyingxenye BIOS ihleli kahle. Ukuthola izibuyekezo zayo kumele kulayishiwe kusuka Umbuso ekhethekile nomkhiqizi umbadlana futhi firmware okuhambisanayo. Lapho agqoke uhlelo ubudala ezilotshwe chip kusulwe, futhi endaweni yawo entsha ebhaliwe. By endleleni, ukuze singene izilungiselelo BIOS kwe-computer siqu, udinga ucindezela ikhi Del ngokushesha ngemuva ukuvula iyunithi uhlelo. Ngemuva kokwenza i-ukulungisa, ungakhohlwa abasindise (inketho ukuphuma imenyu). Bios kwi laptop yenza umsebenzi ofanayo. Umahluko owokuthi ukuthi kulungiselelwa incane kakhulu kunaleyo ikhompyutha agcwele.

Umbhalo esikrinini ukuthi sivela uma uvula - Umklomelo, Ami nasePhoenix Technologies, likhomba izinhlobo BIOS. Nakuba kunezinhlobo ezingaphezu, kodwa computer kuvame kakhulu ukuba kusetshenziswe lezi. Umgomo we operation banayo efanayo. Umehluko baqamekela izigaba ezahlukene isakhiwo imenyu, inani izilungiselelo atholakale umsebenzisi, ukuqaliswa umthwalo yokudlulisela. Okwamanje, i-BIOS zakudala kancane kancane yadedela ngemibono umamukeli yayo - UEFI uhlelo. Kulesi emisha, izici eziningi ezingukhiye BIOS zayo zishintshwe. Ngomqondo onabile, igama UEFI BIOS ingasetshenziswa kuphela nge ukubhuka.
