Chii Bios

Vamwe Varidzi kombiyuta, achangobva akatanga kuongorora nyika muzvigadzirwa kombiyuta, vanogona kunyange vanofungidzira kuti kuwedzera uchishandisa maitiro uye zvirongwa siyana nako unogona kushanda senguva dzose (watinya kaviri - kugadzwa - kutanga), pane nzvimbo yose iri ubatanidzwewo iripo-software yekubvuma. Zviri Chokwadi, anenge ari Bios (Bios).

Ngatione zvinotaura Bios. Kuti kuita zvakawanda pachena, ngationei kutanga muenzaniso. Fungidzira husingaoneki kombiyuta apo uchida vapinze uchishandisa hurongwa windose. Nyorawo zvakakodzera simba netambo kupinda nzira yokubudisa uye kuvaparadzanisa hurongwa chikwata simba bhatani uye ... hapana chinoitika, nekuti kamwe hatizivi chii Bios, ipapo mungarava yake kana kuti kwete. Funga kuti kombiyuta anogona "ziva" kuti unofanira kutanga kudhanilodha kubva zvakaoma nemotokari, uye yakananga? Pashure pezvose, unogona vene kubva nokupenya nemotokari, CD, kunyange munharaunda network. Nei zvakaoma tikachirega? Naizvozvo, tinogona kufunga kuti kumwe pane-software mashandiro ari kombiyuta, kunoita kuti tsanangurai apo kutanga download.

Kufembera yakarurama! Zvirokwazvo uyu ndiye. Pano tinosvika mubvunzo zvinotaura Bios. On chero motherboard chinokosha Chip, izvo fekitari akapinda kudzorwa chirongwa diki. mabasa ayo, Chokwadi, haagarimo imwe nzira vene mudziyo.

Computer basa sezvinotevera: zvinoriumba vose yaipiwa nesimba, ravo dzakawanda controllers kuita nemiedzo vaizviti chirwere uye, kana zvose zvikafamba zvakanaka, isa zvishoma nyoro. Next, kuzvidzora wapfuura kusvikira firmware, iri Bios Chip, izvozvo kutarira matai nokuda kunofambidzana zvinoriumba uye zvavo musarudzo chinzvimbo evoruzhinji. Zvadaro, Bios configures ari IRQ uye DMA mugero vose kwakabatana zvinoriumba. Uyewo maererano SPD hwakaratidza kunonoka RAM modules uye chipset. Zviya, CAS anogona chete kuiswa Panguva iyi, kusvikira ndangariro haasi kushandiswa. It ava pachena kuti Bios ichi?

Kana dambudziko algorithm iri yakapindira kukanganisa mashoko (kungava runyoro chidzitiro kana coded muridzo unoridzirwa hurongwa simba).

The mushandisi anogona kupindira mune Bios kushanda, kuchinja: pakusarudza kuyeuka latency, kurambidza / activation vazhinji akagadzawo zvinoriumba, rairatidza ndarayira polling mano vapinze uchishandisa hurongwa. Kuchinja vanoponeswa nokuda basa voltage mabhatiri iri bhodhi. Mujinga ndiyo chikamu Bios anoramba yakasimba. Nokuti inogadziridza kwayo kunofanira kutorwa kubva motherboard mugadziri wacho chaiye utility uye runoenzanirana firmware. Kana kuvheneka yekare chirongwa kunyorwa Chip zvinodzimwa, uye panzvimbo yayo itsva rakanyorwa. Panzira, apinde Bios zviruva pachedu kombiyuta, unofanira achizviendesa Del kiyi pakarepo pashure akatendeuka pamusoro hurongwa chikwata. Pashure pokutaura kuchinja, usakanganwa kuti kuponesa (kusarudza kuti anongoerekana zviripo). Bios pamusoro Laptop anoita basa rakafanana. Musiyano chete ndechokuti panovira iri shoma zvikuru pane kuti kombiyuta dzakazara.

The IAA chidzitiro inooneka ukadzoka - Award, Ami uye Phoenix Technologies, anotaura kuti mhando Bios. Kunyange zvazvo paine zvakawanda, asi makombiyuta vari zvinowanzoshandiswa izvi. Zvingakubatsira kushanda vane zvakafanana. Kusiyana vavete yakasiyana zvikamu Muterere mamiriro, nhamba mezviruva iripo inodzidzisa, iyo Implementation yacho hutachiwana mutoro. Iye zvino, zimbabwe Bios kupiwa zvishoma nezvishoma nzira kwayo Pfungwa mugamuchiri - UEFI hurongwa. In utsanzi ichi, vakawanda kiyi zvaiva Bios kunge yakadzokororwa. Pfungwa UEFI Bios zita zvingashandiswa chete ndishushikane.
