Incazelo yekhadi lokuhlola le-POST nokuthi lisebenza kanjani
Ikhadi lokuhlola le-POST liyithuluzi elincane lokuxilonga elibonisa amakhodi wephutha okhiqizwa ngesikhathi se- Power On Self Test . Isetshenziselwa ukukhomba izinkinga ezingatholakala uma ikhompyutha iqala.
Lezi ziphutha, ezibizwa ngokuthi ama- POST amakhodi , zihambelana ngqo nokuhlolwa okuhlulekile futhi kungasiza ekunqumeni ukuthi iyiphi ingxenye yehadiwe ebangela inkinga, njengokuthi imemori , ukushayela kanzima , ikhibhodi , njll.
Uma ngabe uhlelo aluhlangabezane nephutha kuze kube yilapho kuqhubeke ngesikhathi senqubo yebhodi ngemuva kokuba ikhibhodi yevidiyo ivuliwe, khona-ke iphutha lingaboniswa esikrinini. Lolu hlobo lwephutha alufani nekhodi ye-POST kepha kunalokho kuthiwa umlayezo wephutha le- POST , okuwumyalezo ofundwa ngumuntu.
Amakhadi wokuhlola we-POST ayaziwa nangokuthi amakhadi we-Power On Self Test, amakhadi we-POST, amakhadi we-POST yokuxilonga, amakhadi wokuhlola, namakhadi angu-80h.
Indlela Amakhadi Evivinyo E-POST asebenza ngayo
Amakhadi amaningi okuhlola we-POST axhuma ngokuqondile emaphaketheni wokunweba ebhodini le- motherboard ngenkathi abanye abambalwa bexhuma kwangaphandle ngechweba elifanayo noma eliyi-serial. Ikhadi lokuhlola le-POST yangaphakathi, yebo, lidinga ukuba uvule ikhompyutha yakho ukuze uyisebenzise.
Phakathi ne-Power On Self Test, ikhodi yamadijithi amabili akhiqizwa futhi ingavame ukufundwa ku-port 0x80. Amanye amakhadi wokuhlola we-POST afaka i- jumpers evumela ukuthi uguqule ukuthi iyiphi i-port yokufunda ikhodi kusukela lapho abanye abakhiqizi basebenzisa ichwethi ehlukile.
Le khodi idalwe ngenkathi isinyathelo ngasinye sokuxilonga ngesikhathi sokuqalisa. Ngemuva kokuthi ucezu olulodwa lwe-hardware lubonakala lusebenza, ingxenye elandelayo ihlolwe. Uma kutholakala iphutha, inqubo ye-bootup ivame ukuma, futhi ikhadi le-POST yokuhlola libonisa ikhodi yephutha.
Qaphela: Kufanele wazi umkhiqizi we-BIOS wekhompyutha yakho ukuze uhumushe amakhodi we-POST kumilayezo yephutha ongawaqonda. Amanye amawebhusayithi, njenge-BIOS Central, abe nohlu lwabathengisi be-BIOS namakhodi abo we-POST ahambisana nawo.
Isibonelo, uma ikhadi le-POST yokuhlola libonisa inombolo yephutha engu-28, futhi uDell ungumkhiqizi we-BIOS, kusho ukuthi ibhethri ye - CMOS RAM iye yahamba kabi. Kulesi simo, ukufaka esikhundleni kwebhethri ye-CMOS cishe kuzosombulula inkinga.
Bheka Iyini Ikhodi ye-POST? uma udinga usizo olungaphezulu ukuqonda ukuthi amakhodi asho ukuthini.
Okuningi mayelana namakhadi wokuhlola we-POST
Njengoba i- BIOS ingaletha umlayezo wephutha ngaphambi kokuba ikhadi levidiyo linikezwe amandla, kungenzeka ukuthi uhlangabezane nenkinga yehadiwe ngaphambi kokuthi umlenze abonise umlayezo. Yilapho ikhadi le-POST lokuhlola lifika kahle - uma iphutha lingenakhululwa esibukweni, ikhadi le-POST yokuhlola lingakusiza ukukhomba inkinga.
Esinye isizathu sokusebenzisa ikhadi le-POST lokuhlola uma ikhompyutha ingakwazi ukwenza umsindo ukunikeza iphutha, yiziphi izinkomba ze-beep . Amakhodi avakalayo ahambisana nomyalezo othile wephutha. Nakuba ziwusizo uma umlayezo wephutha ungakwazi ukuboniswa esikrinini, akuzona neze eziwusizo kuma-computer angenawo isikhulumi sangaphakathi, lapho kwenzeka khona ikhodi ehambisanayo ye-POST ingafundwa kusuka kuhlolo lwe-POST ikhadi.
Bambalwa abantu asebevele bengabanikazi balaba bahloli kepha akubizi kakhulu. Ama-Amazon athengisa amakhadi wokuhlola we-POST, amaningi awo angaphansi kwe $ 20 USD.
