A CMOS Checksum yuam kev yog qhov tsis sib haum xeeb ntawm CMOS (Complementary Metal Oxide Semiconductor) thiab BIOS (Basic Input Output System) uas tshwm sim thaum koj khau raj lub computer. Nws tshwm sim thaum lub khoos phis tawj tsis tuaj yeem nyeem cov ntaub ntawv pib lossis cov ntaub ntawv tsis sib xws.
Nyob hauv phau ntawv qhia no, peb piav qhia qhov ua rau CMOS Checksum yuam kev thiab muab cov lus qhia rau kev daws teeb meem thiab kho qhov teeb meem.
Ua rau CMOS Checksum yuam kev
Muaj ntau yam laj thawj rau CMOS checksum yuam kev, tab sis yuav luag txhua tus rov qab los rau cov ntaub ntawv ntawm CMOS ua tsis ncaj rau ib qho lossis lwm qhov.
Ua ntej lub operating system khau raj, lub khoos phis tawj motherboard ua haujlwm ntau yam haujlwm qis, npaj cov txheej txheem ua haujlwm kom khiav thiab thaum kawg muab cov haujlwm no tawm mus rau lub operating system. Lub software ntawm lub motherboard yog hu ua BIOS. Ntxiv nrog rau kev pib lub khoos phis tawj, BIOS muaj ntau qhov chaw rau nws cov khoom siv, xws li kev nrawm, qhov hluav taws xob, lub sijhawm ua haujlwm, thiab qhov tseem ceeb ntawm khau raj. Cov kev teeb tsa BIOS tsis tau khaws cia hauv lub hard drive. Lawv nyob ntawm lub nti hu ua CMOS.
Thaum twg koj hloov pauv rau BIOS nqis, pib koj lub khoos phis tawm, lossis kaw nws, cov xwm txheej tau sau rau CMOS. Nws khaws cov ntaub ntawv kom paub tseeb tias cov khoom ua haujlwm ib txwm ua rau lwm zaus koj pib lub computer. Lub CMOS nyob twj ywm thaum lub sijhawm so ntawm lub khoos phis tawj tawm vim tias nws tau siv nws tus kheej los ntawm lub roj teeb saib. Thaum lub khoos phis tawj pib, nws nyeem lub xeev nws tau dhau los ntawm CMOS. Feem ntau, nws tuaj yeem nyeem cov ntaub ntawv thiab kho nws tus kheej yam tsis muaj teeb meem. Qhov yuam kev CMOS Checksum tshwm sim thaum lub khoos phis tawj tsis tuaj yeem nyeem cov ntaub ntawv ntawd.
Ib qho ntawm ntau qhov ua rau ntawm qhov yuam kev checksum kuj yog qhov yooj yim tshaj los daws. Lub roj teeb uas siv lub zog CMOS yog lub roj teeb saib, thiab nws tuaj yeem khiav tawm ntawm lub zog. Thaum lub roj teeb tuag, CMOS khaws tsis tau cov ntaub ntawv ntxiv lawm.
Lub zog surges thiab tam sim ntawd poob ntawm lub hwj chim yog lwm yam ua rau. Yog tias lub khoos phis tawj tsis muaj sijhawm los sau cov ntaub ntawv rau CMOS ua ntej nws raug kaw sai sai, nws muaj lub sijhawm nyuaj los khaws qhov twg nws tawm mus. Lub zog hluav taws xob kuj tuaj yeem ua rau kev noj nyiaj txiag lossis khoom siv puas tsuaj.
Qhov kawg ua rau muaj tsawg, tab sis nws tuaj yeem tshwm sim. Yog tias BIOS puas lossis puas, nws yuav ua rau tsis sib haum xeeb ntawm BIOS thiab CMOS. Nws tsis tshua muaj tab sis muaj peev xwm kis tau tus kab mob thiab ua rau lub BIOS tsis raug. Txawm li cas los xij, nws muaj ntau dua tias BIOS hloov tshiab ua tsis tiav lossis lub operating system tau hloov kho qee yam uas ua rau nws tawm ntawm sync nrog BIOS.
Yuav ua li cas kho CMOS Checksum yuam kev
Thaum nws tsis tuaj yeem kho qhov yuam kev CMOS checksum, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv kho vajtse puas, qhov kho feem ntau yog yooj yim. Ua raws li cov kauj ruam no, txhawm rau daws qhov yuam kev.
- Restart lub computer. Ib qho pib rov pib dua qub feem ntau tsim ib qho checksum tshiab thiab tshem tawm qhov yuam kev. Qhov yuam kev nyob tom qab rov pib dua ib txwm xav tau qee qhov haujlwm ntxiv.
- Download thiab nyem lub BIOS hloov tshiab. Download tau qhov hloov tshiab los ntawm cov chaw tsim khoom motherboard lub vev xaib. Ntau lub motherboards tuaj yeem rub tawm qhov hloov tshiab los ntawm hauv BIOS thaum lawv txuas rau hauv koj lub network siv Ethernet cable.
-
Reset BIOS. Qee lub motherboards muaj qhov hloov pauv ntawm lub rooj tsavxwm lossis sab nraub qaum ntawm lub khoos phis tawj kom rov pib dua BIOS nqis. Yog tias tsis muaj qhov hloov pauv li ntawd, tshem tawm CMOS roj teeb ntawm koj lub cev rau ib feeb lossis ob zaug. Lub zog poob ua rau txhua yam hauv CMOS rov pib dua.
- Hloov lub roj teeb CMOS. Yog tias qhov ua rau yog lub roj teeb tuag, txhua yam koj xav tau yog ib qho tshiab. Lub CMOS roj teeb nyob ntawm lub computer lub motherboard. Ntawm desktops, nws yooj yim mus rau, thiab nws tsuas yog tuav nyob rau hauv qhov chaw nrog ib tug hlau clip. Ntawm lub laptops, koj yuav tsum qhib lub tshuab kom nkag mus rau lub motherboard, thiab qhov ntawd yuav zoo dua rau tus kws tshaj lij.
- Tham nrog tus kws tshaj lij lossis kws kho computer. Yog tias tag nrho cov saum toj no ua tsis tiav, qhov teeb meem yuav yog vim kev puas tsuaj ntawm cov khoom siv. Ua ntej koj yuav ib lub motherboard tshiab lossis rov siv lub tshuab, muaj tus kws tshaj lij xyuas kom paub tseeb.
FAQ
Checksum yog dab tsi?
A checksum yog ib qho algorithm siv nyob rau hauv ntau cov kev pab cuam kom paub meej tias kev ncaj ncees ntawm cov ntaub ntawv. Qhov no yog siv ntau zaus hauv cov kev pab cuam rub tawm kom paub meej tias cov ntaub ntawv tsis tau raug cuam tshuam los yog puas.
Kuv yuav kho qhov yuam kev checksum hauv WinRAR li cas?
Sim siv WinZip los kho cov ntaub ntawv. Ua li no, right-click rau ntawm cov ntaub ntawv thiab xaiv Extract file. Tom ntej no, mus rau Mscellaneous thiab tso lub cim ntawm ib sab ntawm Keep Broken Files ces xaiv qhov chaw rho tawm thiab xaiv OK.
