Ib daim video card yog ib qho ntawm feem ntau txheej txheem ntawm lub computer niaj hnub. Nws muaj xws li nws tus kheej microprocessor, video nco slots, thiab raws li nws tus kheej BIOS. Cov txheej txheem ntawm kev muab kho dua cov BIOS rau hauv daim npav video yog me ntsis nyuab dua rau hauv computer, tab sis nws yuav tsum tau tsawg dua.
Saib kuj: Kuv puas xav hloov BIOS
Ceeb toom ua ntej ua haujlwm
Ua ntej koj pib hloov kev txhim kho BIOS, koj yuav tsum kawm cov ntsiab lus hauv qab no:
- BIOS rau cov ntawv teev lus video uas tau muab tso rau hauv lub tshuab los sis cov niam ntawv (feem ntau zoo li no nyob hauv laptops), tsis tas yuav muaj kev hloov tshiab, vim lawv tsis muaj nws;
- Yog tias koj siv ntau daim npav discrete, ces koj tuaj yeem hloov kho ib zaug ib zaug, so thaum lub sijhawm hloov tshiab yuav tsum tau kaw thiab ntsaws rau tom qab txhua yam npaj txhij lawm;
- Tsis tas yuav hloov siab yam tsis muaj lub laj thawj zoo, piv txwv li, tsis tsim nyog nrog cov khoom siv tshiab yuav zoo li no. Nyob rau hauv lwm yam, flashing yog impractical.
Theem 1: npaj ua haujlwm
Hauv kev npaj, koj yuav tsum ua cov nram qab no:
- Tsim ib daim qauv thaub qab ntawm tam sim no firmware, yog tias thaum muaj teeb meem koj tuaj yeem ua tus thaub qab;
- Kawm kom ntxaws yam ntxwv ntawm daim video;
- Download tau qhov firmware tseeb.
Siv phau ntawv qhia no kom paub txog tus yam ntxwv ntawm koj daim video thiab rov qab tuaj rau BIOS:
- Download thiab nruab rau qhov kev pab cuam TechPowerUp GPU-Z, uas yuav cia koj ua tiav ib daim video.
- Txhawm rau saib cov yeeb yam ntawm cov video adapter, tom qab qhib lub software, mus rau lub tab "Daim Duab" nyob hauv daim ntawv qhia zaub mov saum toj kawg nkaus. Nco ntsoov xyuam xim rau cov khoom uas tau kos rau hauv lub screenshot. Nws yog ib qho tsim nyog kom txuag tau qhov chaw qhia qhov tseem ceeb, vim tias koj xav tau lawv yav tom ntej.
- Ncaj nraim los ntawm qhov kev pab cuam koj tuaj yeem ua tau ib daim qauv ntawm daim video BIOS. Ua li no, nyem rau ntawm daim duab icon, uas nyob sab nraum lub tshav pob "BIOS version". Thaum koj nyem rau nws, qhov kev zov me nyuam yuav tau xaiv los txiav txim siab. Hauv qhov no, koj yuav tsum xaiv qhov kev xaiv "Tseg rau ntaub ntawv ...". Tom qab ntawd koj yuav tsum tau xaiv ib qho chaw los cawm ib daim qauv.
Tam sim no koj yuav tsum download tau qhov tseeb BIOS version los ntawm cov khw muag khoom lub vas sab (lossis lwm yam kev pabcuam uas koj ntseeg tau) thiab npaj rau kev txhim kho. Yog hais tias koj xav tau hloov lub teeb duab ntawm daim video nrog flashing, ces tus edited BIOS version tau downloaded los ntawm ntau qhov chaw thib peb. Thaum daus los ntawm cov kev pab li no, nco ntsoov xyuas cov ntaub ntawv downloaded rau cov kab mob thiab qhov tseeb ntxiv (yuav tsum yog ROM). Nws kuj tseem pom zoo kom mus download tau qhov chaw tshwj xeeb tshaj tawm los ntawm qhov chaw cia siab.
Cov ntaub ntawv downloaded thiab cov ntawv ceev cia yuav tsum tau xa mus rau USB flash drive los ntawm lub tshuab fais fab tshiab. Ua ntej koj siv USB flash drive, nws pom zoo kom format nws kiag li, thiab tsuas ces hla ROM-ntaub ntawv.
Theem 2: ntsais muag
Tshaj tawm lub BIOS ntawm ib daim video yuav xav kom cov neeg siv ua haujlwm nrog ib qho analog "Hais kom ua kab" - DOS. Siv cov kauj ruam no los ntawm kev qhia kauj ruam:
- Khau raj koj lub computer los ntawm kev tsav tsheb nrog firmware. Nrog lub khau raj zoo, tsis txhob siv lub operating system los yog tus txheem BIOS, koj yuav tsum pom DOS interface, uas zoo li niaj zaus "Hais kom ua kab" ntawm qhov rais.
- Nws yog tsim nyog nco ntsoov tias nyob rau hauv no txoj kev nws yog ua tau kom reflash tsuas yog ib qho video-card nkaus xwb. Nrog kev pab los ntawm qhov hais kom ua -
nvflash - cov npeKoj tuaj yeem paub cov xov tooj ntawm cov processors thiab cov ntaub ntawv ntxiv txog daim video. Yog tias koj muaj ib daim yuaj video card, cov ntaub ntawv hais txog lub rooj tsav khoom yuav tsum muab tso tawm. Muab tias tus adapter muaj ob lub txheej txheem, lub tshuab computer yuav tau kuaj ob daim video. - Yog hais tias txhua yam yog ib txwm, ces rau ib lub ntsej muag zoo ntawm NVIDIA video card, koj yuav tau pib tua lov tawm BIOS overwrite kev tiv thaiv, uas yog enabled los ntawm default. Yog tias koj tsis lov tes taw, overwriting yuav tsis tuaj yeem los tsis ua kom raug. Txhawb txoj kev tiv thaiv, siv qhov hais kom ua
nvflash - protectctoff. Tom qab nkag mus rau qhov kev hais kom ua, lub computer tuaj yeem nug koj kom paub meej txog qhov tiav, vim qhov no koj yuav tsum nias ib qho Sautxawm yog Y (nyob ntawm BIOS version). - Tam sim no koj yuav tsum nkag mus rau ib lo lus txib uas qhia qhov BIOS. Nws zoo li no:
nvflash -4 -5 -6(cov ntaub ntawv lub npe nrog cov ntaub ntawv BIOS tam sim no).rom - Thaum ua tiav, pib dua lub computer.
Saib kuj: Yuav ua li cas los tsim khau raj ntawm USB flash tsav hauv BIOS
Yog tias qee qhov laj thawj video card nrog cov tshiab BIOS tsis kam ua haujlwm los yog tsis ruaj tsis khov, ces thawj zaug sim downloading thiab txhim kho tsav rau nws. Muab hais tias qhov no tsis pab, koj yuav tau rov qab txhua yam kev hloov rov qab. Ua li no, siv cov lus qhia dhau los. Tsuas yog tias nyob rau hauv pawg lus thib 4 koj yuav tsum hloov lub npe ntawm cov ntaub ntawv rau ib qho uas nqa cov ntaub ntawv nrog lub backup firmware.
Nyob rau hauv cov ntaub ntawv koj yuav tsum tau hloov lub firmware rau ob peb video adapters ib zaug, koj yuav tsum disconnect daim card uas twb tau raug kho tshiab, txuas ntxiv rau ib qho thiab ua ib yam nrog nws raws li yav dhau los ib. Ua tib yam li cov nram qab no kom txog rau thaum cov adapters tshiab.
Tsis tas yuav tsum tau ua kom muaj kev tswj hwm nrog BIOS ntawm daim video card tsis pom zoo. Piv txwv, koj tuaj yeem kho tus zaus nrog qhov kev pabcuam tshwj xeeb rau lub qhov rais los yog siv cov kev siv tus qauv hauv BIOS. Ntxiv thiab, tsis txhob sim nruab ntau versions of firmware los ntawm unverified sources.
