CMOS (luv luv rau cov hlau-oxide-semiconductor) yog lo lus feem ntau siv los piav txog qhov me me ntawm lub cim xeeb ntawm lub khoos phis tawj motherboard uas khaws cov chaw BIOS. Qee qhov BIOS teeb tsa no suav nrog lub sijhawm thiab hnub tim, nrog rau kev teeb tsa kho vajtse.
A CMOS duab sensor txawv-nws tau siv los ntawm cov koob yees duab digital los hloov cov duab rau hauv cov ntaub ntawv digital.
Lwm lub npe rau CMOS
CMOS (hais pom-moss) qee zaum hu ua Real-Time Clock (RTC), CMOS RAM, Non-Volatile RAM (NVRAM), Non-Volatile BIOS nco, lossis ntxiv-symmetry hlau-oxide- semiconductor (COS-MOS).
CMOS kuj yog cov ntawv luv rau lwm cov ntsiab lus uas tsis cuam tshuam nrog qhov tau tham txog ntawm nplooj ntawv no, xws li kev tswj hwm ntawm tes ntawm tes thiab kev sib piv cov txiaj ntsig kev xav.
Kev tshem tawm CMOS
Feem ntau hais lus ntawm CMOS cuam tshuam nrog kev tshem tawm CMOS, uas txhais tau hais tias rov pib dua BIOS nqis rau lawv cov theem pib. Nov yog ib txoj haujlwm yooj yim heev uas yog ib qho kev daws teeb meem zoo rau ntau hom teeb meem hauv computer.
Piv txwv li, tej zaum koj lub khoos phis tawj khov thaum lub sijhawm POST, nyob rau hauv rooj plaub uas tshem tawm CMOS kom rov pib dua BIOS nqis rau lub Hoobkas ua haujlwm, tej zaum yuav yog qhov kev daws teeb meem yooj yim tshaj plaws.
Los yog tej zaum koj yuav tsum tau tshem CMOS kom rov pib teeb tsa BIOS teeb tsa tsis raug los kho qee yam khoom siv yuam kev, xws li Code 29 yuam kev. Lwm qhov yuam kev CMOS rov tshwm sim nyob ib puag ncig lub roj teeb qis, CMOS checksum, roj teeb tsis ua haujlwm, thiab nyeem ntawv yuam kev.
Yuav ua li cas BIOS thiab CMOS ua haujlwm ua ke
BIOS yog lub khoos phis tawj nti ntawm lub motherboard zoo li CMOS, tshwj tsis yog tias nws lub hom phiaj yog sib txuas lus ntawm cov processor thiab lwm yam khoom siv kho vajtse xws li hard drive, USB ports, suab card, video card, thiab ntau dua. Lub khoos phis tawj uas tsis muaj BIOS yuav tsis nkag siab tias cov khoom ntawm lub khoos phis tawj no ua haujlwm ua ke li cas.
Lub BIOS firmware kuj tseem yog qhov ua rau Lub Hwj Chim Ntawm Kev Ntsuas Tus Kheej los kuaj cov khoom kho vajtse, thiab dab tsi thaum kawg khiav lub bootloader los pib lub operating system.
CMOS tseem yog lub khoos phis tawj nti ntawm lub motherboard, lossis tshwj xeeb tshaj yog RAM nti, uas txhais tau tias nws ib txwm yuav poob qhov chaw nws khaws cia thaum lub khoos phis tawj kaw (ib yam li yuav ua li cas cov ntsiab lus ntawm RAM tsis khaws cia. txhua zaus koj rov pib koj lub computer). Txawm li cas los xij, CMOS roj teeb yog siv los muab lub zog tas li rau lub nti.
Thaum lub khoos phis tawj pib ua ntej, BIOS rub cov ntaub ntawv los ntawm CMOS nti kom nkag siab txog cov khoom siv kho vajtse, sijhawm, thiab lwm yam uas tau khaws cia hauv nws. Lub nti feem ntau khaws cia tsawg li 256 bytes ntawm cov ntaub ntawv.
CMOS Roj teeb yog dab tsi?
Lub CMOS feem ntau yog siv los ntawm npib qhov loj ntawm CR2032 roj teeb ntawm tes, hu ua CMOS roj teeb.
Feem ntau CMOS roj teeb yuav kav lub neej ntawm lub motherboard, mus txog 10 xyoo nyob rau hauv feem ntau, tab sis qee zaus yuav tsum tau hloov nyob ntawm seb lub cuab yeej siv li cas.
Hnub thiab sijhawm tsis raug lossis qeeb qeeb, thiab poob ntawm BIOS nqis, yog cov cim tseem ceeb ntawm lub roj teeb CMOS tuag lossis tuag.
Hloov lub roj teeb CMOS yog qhov yooj yim li swapping tus tuag rau ib qho tshiab. Koj tuaj yeem tau txais lub roj teeb CMOS tshiab ntawm Amazon thiab los ntawm lwm cov khw muag khoom uas muag cov khoom hloov lub computer.
Ntau Txog CMOS & CMOS roj teeb
Txawm hais tias feem ntau cov motherboards muaj qhov chaw rau CMOS roj teeb, qee lub khoos phis tawj me, zoo li ntau lub ntsiav tshuaj thiab laptops, muaj qhov me me sab nraud rau lub roj teeb uas txuas rau lub motherboard ntawm ob lub xov hlau me me.
Qee yam khoom siv uas siv CMOS suav nrog microprocessors, microcontrollers, thiab static RAM (SRAM).
Nws yog ib qho tseem ceeb kom nkag siab tias CMOS thiab BIOS tsis yog cov ntsiab lus sib hloov tau rau tib yam. Thaum lawv ua haujlwm ua ke rau ib qho haujlwm tshwj xeeb hauv computer, lawv yog ob qho sib txawv kiag li.
Thaum lub khoos phis tawj pib ua ntej, muaj kev xaiv khau raj rau hauv BIOS lossis CMOS. Qhib CMOS teeb tsa yog li cas koj tuaj yeem hloov qhov chaw nws khaws cia, zoo li hnub thiab sijhawm thiab qhov sib txawv ntawm lub khoos phis tawj tau pib ua ntej. Koj tseem tuaj yeem siv CMOS teeb tsa los kaw / qhib qee cov khoom siv kho vajtse.
CMOS chips yog qhov xav tau rau cov khoom siv roj teeb zoo li lub laptops vim tias lawv siv lub zog tsawg dua li lwm hom chips. Txawm hais tias lawv siv ob qho tib si tsis zoo polarity circuits thiab zoo polarity circuits (NMOS thiab PMOS), tsuas yog ib hom hluav taws xob hluav taws xob ib zaug xwb.
Mac sib npaug rau CMOS yog PRAM, uas sawv cev rau Parameter RAM. Koj tuaj yeem rov pib dua koj Mac's PRAM.
FAQ
Dab tsi yog cov tsos mob ntawm CMOS roj teeb tsis ua haujlwm?
Ntau qhov teeb meem tuaj yeem cuam tshuam nrog CMOS tsis ua haujlwm. Piv txwv li, yog hais tias lub laptop muaj teeb meem booting, tsis tuaj yeem txuas rau hauv internet, los yog tsis tu ncua beeping. Lwm cov tsos mob muaj xws li cov neeg tsav tsheb ploj mus, cov khoom siv tsis tau teb, thiab hnub thiab sijhawm rov pib dua.
CMOS Checksum yuam kev yog dab tsi?
A CMOS Checksum yuam kev yog qhov tsis sib haum xeeb ntawm CMOS thiab BIOS thaum booting. Koj tuaj yeem kho qhov yuam kev no los ntawm kev ua raws li ob peb kauj ruam daws teeb meem, suav nrog rov pib lub khoos phis tawj, rub tawm thiab nyem lub BIOS hloov tshiab, rov pib dua BIOS, thiab tej zaum yuav hloov lub roj teeb CMOS.
