Yuav ua li cas yog BIOS

Ib txhia computer tswv, tsuas yog nyuam qhuav pib mus tshawb lub ntiaj teb no ntawm lub computer technology, tej zaum yuav tsis txawm xav tias nyob rau hauv tas li ntawd mus rau lub operating system thiab ntau yam kev pab cuam uas koj yuav ua hauj lwm raws li ib txwm (ob npaug nias - installation - pib), muaj tag nrho cov cheeb tsam yog cov muaj software code. Nws yog, ntawm chav kawm, hais txog lub BIOS (BIOS).

Cia peb kawm saib ua li cas rau lub BIOS. Yuav kom ua rau nws ntshiab, cia tus pib nrog ib qho piv txwv. Xav txog tej yam paub daws teeb computer uas koj xav kom thauj cov operating system windose. Muaj xws li tsim nyog lub hwj huam qaum rau hauv lub qhov hluav taws xob thiab thawb lub system unit hwj huam khawm thiab ... tsis muaj dab tsi tshwm sim, vim hais tias thaum peb tsis paub dab tsi lub BIOS, ces nyob rau hauv nws lub Rooj Tswjhwm Saib los yog tsis. Xav txog yuav ua li cas lub computer yuav "paub" hais tias koj yuav tau pib ua daus los ntawm lub zog tsav, thiab tej? Tom qab tag nrho, koj muaj peev xwm khau raj los ntawm ib tug flash drive, CD, txawm nyob rau ib lub zos network. Yog vim li cas yog lub zog tsav? Yog li ntawd, peb yuav hais tsis xav hais tias qhov chaw yog ib tug software mechanism nyob rau hauv ib lub computer, tso cai rau koj kom meej rau qhov twg pib lub download.

Xam yog muaj tseeb! Qhov no yog. Ntawm no yog peb tuaj mus rau rau lo lus nug ntawm yog dab tsi lub BIOS. Nyob rau motherboard yog ib tug tshwj xeeb nti, uas muaj ib tug Hoobkas nkag mus hauv ib tug me me tswj qhov kev pab cuam. Nws zog yog, ntawm chav kawm, tsis ceev ib txoj kev khau raj ntaus ntawv.

Khoos phib tawj ua hauj lwm yog raws li nram no: tag nrho cov Cheebtsam yog muab nrog lub hwj chim, lawv nrog controllers ua self-diagnostic kev ntsuam xyuas thiab, yog tias tag nrho cov mus zoo, muab tso rau ib tug me ntsis kev sib tw uas. Tom ntej no, tswj yog kis mus rau cov firmware, nyob rau hauv lub BIOS nti, nws scans cov log tsheb rau lub kev cob cog rua lub Cheebtsam thiab lawv polls raws li txoj cai sau. Tom qab ntawd, BIOS configures tus IRQ thiab DMA raws rau tag nrho cov kev cob cog rua lub Cheebtsam. Tsis tas li ntawd nyob rau hauv raws li SPD tshaaj ncua RAM modules thiab chipset. Los ntawm txoj kev, CAS yuav tsuas yuav teem rau ntawm no theem, mus txog rau thaum lub cim xeeb yog tsis tau siv. Nws tau tam sim no kom meej tias qhov no BIOS?

Yog hais tias ib qho teeb meem algorithm yog tu ncua thiab ib qho yuam kev lus (nws yuav yog tus sau ntawv rau qhov kev tshuaj ntsuam los yog coded piping system puab).

Tus neeg siv yuav cuam tshuam nyob rau hauv lub BIOS mus ua hauj lwm, ua kev kho me ntsis: xaiv ntawm lub cim xeeb latency, kev txwv tsis pub / ua kom muaj ntau lub ntsia lub Cheebtsam, ib tug hais txog ntawm qhov kev txiav txim ntawm polling li thauj cov operating system. Cov kev hloov tau txais kev cawmdim vim yog lub luag hauj lwm voltage roj teeb nyob rau ntawm lub Rooj Tswjhwm Saib. Lub hauv paus yog ib feem ntawm lub BIOS tseem lawm. Rau nws cov tshiab yuav tsum tau downloaded ntawm lub motherboard chaw tsim tshuaj paus tshwj xeeb nqi hluav taws xob thiab cov coj firmware. Thaum flashing lub qub kev pab cuam sau nyob rau hauv lub nti yog erased, thiab nyob rau hauv nws qhov chaw ib tug tshiab sau. Los ntawm txoj kev, yuav tau mus rau hauv lub BIOS tej chaw ntawm koj tus kheej lub computer, koj yuav tsum nias lub Del tseem ceeb tam sim ntawd tom qab xa rau lub system unit. Tom qab ua lub kev kho me ntsis, tsis txhob hnov qab mus cawm lawv (cov kev xaiv kom tawm cov zaub mov). BIOS rau lub laptop ua tib yam muaj nuj nqi. Qhov txawv tsuas yog tias qhov chaw ntawd yog npaum li cas tsawg tshaj li uas ntawm ib tug tag nrho-fledged computer.

Lub inscription ntawm qhov screen uas zoo nkaus li thaum koj tig - puav pheej, Ami thiab Phoenix yees, cov ntsiab lus rau lub hom BIOS. Txawm hais tias muaj ntau, tab sis computers yog feem ntau siv no. Hauv paus ntsiab lus ntawm cov lag luam lawv muaj tib lub. Lub sib txawv pw nyob rau hauv qhov sib txawv seem ntawm cov zaub mov qauv, lub xov tooj ntawm cov chaw muaj rau cov neeg siv, qhov kev siv ntawm cov kis load. Tam sim no, classic BIOS yog maj muab txoj kev rau nws cov ideological receiver - UEFI system. Nyob rau hauv no innovation, ntau tseem ceeb nta ntawm lub BIOS tau kho. Nyob rau hauv hauv paus ntsiab lus, UEFI BIOS npe yuav siv tau tsuas yog nrog reservations.
