Yintoni BIOS

Ezinye abanini computer, kutshanje nje waqalisa ukuvavanya ihlabathi lobuchwepheshe computer, ukuze nkqu sokukrokra ukuba ukongeza kwindlela yokusebenza kunye neenkqubo ezahlukeneyo uyakwazi ukusebenza ngokwesiqhelo ngayo (ngonqakrazo kabini - ufakelo - qala), kukho indawo yonke ifumaneka inxalenye ikhowudi software. Ngoko ke, Kakade ke, malunga i-BIOS (BIOS).

Makhe sibone ukuba yintoni i-BIOS. Ukwenza kucace ngakumbi, makhe siqale umzekelo. Khawucinge athile ikhompyutha apho ufuna ukulayisha Indlela yokusebenza ye windose. Quka intambo kufanelekileyo lo walivala ithende nizihlabe iyunithi inkqubo iqhosha amandla ... akukho nto yenzekayo, ngokuba kanye asazi ukuba uhlelwe yintoni na BIOS, ngoko nebhodi yakhe okanye hayi. Cinga ngendlela ikhompyutha nga 'siyazi' ukuba kufuneka uqale uzilayishe ezantsi kwi-hard drive, kanye ngqo? Ngapha koko, ungenza ukuziqala ukusuka flash drive, CD, de womnatha. Kutheni na hard drive? Ngoko ke, simele sicinge ukuba ethile kukho indlela software kwikhompyutha, ekuvumela ukuba ukhankanye ukuqalisa umxokozelo apho.

Uqikelelo ilungile! ngokwenene oku. Apha siza kumbuzo into BIOS. On nayiphi motherboard na chip okhethekileyo, nto leyo eye wangena inkqubo yolawulo encinane-mveliso. imisebenzi yalo, Kakade ke, ayipheleli elinye icebo ukhetho idrive.

umsebenzi computer ngolu hlobo lulandelayo: onke amacandelo unikwa igunya, nabaqondisi zazo zangaphakathi enze iimvavanyo self-diagnostic kunye, ukuba konke kuhamba kakuhle, faka ithenda bit. Okulandelayo, ulawulo zigqithiswe firmware, ibekwe chip BIOS, sifunda amavili yezigqeba ezidityanisiweyo kunye zabo iirejista ngokweentloko status. Emva koko, lo BIOS Iqwalasela i IRQ kunye DMA iitshaneli onke amacandelo enxulumene. Kwakhona ngokungqinelana SPD yabamba iimodyuli RAM ukulibaziseka kunye chipset. Hi ndlela leyi, CAS zingasetwa kuphela kweli nqanaba, kude kube imemori oku akusetyenziswa. ngoku Kuye kwacaca ukuba lo BIOS?

Ukuba algorithm ingxaki uphazamiseka kunye umyalezo wemposiso (ingaba umbhalo kwikhusi okanye amandla inkqubo igiza iibhakhowudi).

Umsebenzisi angangenelela BIOS ukusebenza, ukwenza uhlengahlengiso: kukhethwe engenamnini memory, isalelo / ukusebenza ezininzi iinxalenye efakiweyo, ebonisa indlela izixhobo ubalo ukulayisha indlela yokusebenza. Olu tshintsho zigcinwa ngenxa neebhetri umsebenzi ombane ibekwe ebhodini. Isiseko yinxalenye BIOS ayitshintshanga. Kuba updates zayo kufuneka ezantsi ukusuka eluncedo kumenzi motherboard akhethekileyo kaThixo kunye firmware ahambelanayo. Xa ebengezelayo inkqubo endala ezibhalwe chip isuswa, kwaye endaweni yayo entsha ebhaliweyo. Ngendlela, ukuba bangene useto BIOS ye computer siqu, kufuneka cofa iqhosha Del ngoko nangoko emva kokuqinisekiswa kwinkqubo unit kulo. Emva kokwenza uhlengahlengiso, musa ukulibala Wabasindisa (ukhetho ukuphuma menu). BIOS kwi laptop owenza umsebenzi ofanayo. Umahluko kuphela kukuba Ukumiswa ngaphantsi kakhulu kunalowo ikhompyutha yinxalenye.

Umbhalo kwikhusi evela xa uvula - Award, Ami kunye Phoenix Technologies, salatha iindidi BIOS. Nangona kukho ngakumbi, kodwa computers amaninzi kusetyenziswa ezi. Siseko ukusebenza babe efanayo. Umahluko kulala kumacandelo ahlukeneyo isakhiwo menu, inani izicwangciso ezikhoyo kumsebenzisi, ukuphunyezwa umthwalo ugqithiso. Okwangoku, i-BIOS zakudala kuxhaphaka unika indlela yayo ngumamkeli wawo - inkqubo UEFI. Kule ezintsha, abaninzi iimpawu ezingundoqo ze-BIOS ziye zahlaziywa. Enyanisweni, igama UEFI BIOS zingasetyenziswa kuphela ndandithingaza.
