Maqaalkan, waxaan ka wada hadli doonaa waxa uu yahay BIOS Whitelist , waa maxay isticmaalkiisa, iyo sida loo saaro. Marka la soo koobo, liiska cad ee BIOS asal ahaan waa liis qalab ah oo loo oggolaaday in lagu isticmaalo kombuyuutarkaas - haddii aad isku daydo inaad isticmaasho wax kale, kumbiyuutarku ma ogaan doono. OEM^(OEMs) -yadu waxay u isticmaalaan liiska cad ee BIOS ee qalabka si ay u xaddidaan isticmaaleyaasha inay iibsadaan nooc kasta oo kale.

BIOS waxay u taagan tahay Nidaamka Wax-soo-saarka Aasaasiga ah . Waa qayb ka mid ah nidaamka kumbiyuutarka ee hubiya kumbiyuutarka ka hor inta aan la shubin nidaamka hawlgalka. Qaar ka mid ah hawlaha muhiimka ah ee BIOS waa:

1. Hubinta waxa dhammaan qalabka ku xiran kombayutarka Liiskaas waxaa ku jira mouse, kiiboodhka, joysticks, iwm.
2. Raraya wadayaasha qalabka iyo hubinta cilladaha. Kumbuyuutarku wuxuu ku siinayaa fariin qalad ah mid ka mid ah darawalada lama heli karo. Tusaale ahaan, haddii aan la helin kiiboodhka, waxay odhanaysaa, " Keyboard -ka lama helin". Tani waa ka hor inta aan la shubin nidaamka hawlgalka
3. Waxa kale oo ay maamushaa RAM ilaa nidaamka hawlgalka uu la wareego
4. Ka dib marka la tijaabiyo qalabka boot ( HDD ama DVD ama Flash Drive) cilladaha, waxay ku shubtaa qaybaha hoose ee OS RAM . Halkaa, nidaamka hawlgalka ayaa la wareegaya.

Waa maxay BIOS Whitelist

Liistada cad-cad guud ahaan waa liiska barnaamijyada, software-ka, iyo faylalka nidaamka ee loo ogolyahay kombayutarka. Haddii uu jiro firewall, waxaa laga yaabaa inaad horey u abuurtay liiska barnaamijyada geli kara internetka^(Internet) . Kaasi waa liiska cad-cad ee firewall-ka. Liiska cad ee BIOS^{(BIOS Whitelist)} sidoo kale wuxuu ku shaqeeyaa khadadka la midka ah.

Haddii aad ku darto qalab cusub kombiyuutarkaaga ama aad bedesho qalab duug ah oo burburay, kumbiyuutarku wuxuu marka hore eegi doonaa liiska cadeymaha ee BIOS si uu u eego in qalabkaas gaarka ah ( sumadda, samaynta, ama moodelka) la oggol yahay.

Haddaba, liiska cad ee BIOS asal ahaan waa liis qalabeed loo oggolaaday in lagu isticmaalo kombayutarkaas. Haddii aad isku daydo inaad isticmaasho wax kale, kumbuyuutarku ma ogaan doono. Waxaa laga yaabaa inaad waydiiso sababta liiska cad ee BIOS^(BIOS) loogu baahan yahay. Baaragaraafyada soo socdaa waxay ka hadlayaan isticmaalka liiska caddaymaha ee BIOS .

Waa maxay isticmaalka BIOS whitelist

Isticmaalka loogu talagalay liiska cadeymaha BIOS waa in la arko in isticmaalayaasha dhamaadka aysan ku rakibin qalab kasta oo sababi kara khilaaf qalabyada kale ee kombiyuutarka. Liistada cad ee BIOS macnaheedu waa liis ay ku qoran yihiin dhammaan qalabyada uu qofku ku isticmaali karo kombiyuutarka iyada oo aan la khilaafin qalabka jira.

Laakiin taasi waa sidaas shalay. Ujeedada dhabta ah ee liiska cad ee BIOS , fikradayda, waa in la xannibo qaybaha qalabka laga soo iibsado nooc kasta oo kale iyo calaamad. Tusaale ahaan, haddii aad kumbuyuutar ka soo iibsatid astaanta XYZ , oo aad rabto inaad ku darto kaarka shabakadda Wi-Fi, waa inaad soo iibsataa kuwa liiska cadcad ku leh BIOS . Tani waxay si aad ah uga dhigan tahay in calaamaduhu ay xaddidayaan fursadahaaga si aad ugu dhejisid calaamad la mid ah kan kombiyuutarka aad haysato.

Waa maxay sababta isticmaalayaashu aysan u jeclayn liiska cad ee BIOS

Sida kor looga hadlay, dhammaan soo saarayaasha kombuyuutarku maaha kuwo OK dadka isticmaalaya nooc kasta oo qalab kale oo kombayuutarkooda ah. Sidaa darteed^(Hence) , waxay ku xoojiyaan xannibaadaha magaca BIOS Whitelist . Xitaa haddii aad haysato qalab ku habboon sida kaarka shabakadda, ma isticmaali kartid haddii uusan ku jirin liiska cad ee BIOS . Taasi waa sababta ugu weyn ee dadku aysan u rabin liiska cad ee BIOS .

Haddii aysan jirin liis cad oo ku jira BIOS ama haddii la damiyo, isticmaalayaashu waxay isticmaali karaan qalab kasta oo ay rabaan - kumbuyuutarka asalka ah. Si aad ugu rakibto qalab kasta kombuyuutar calaamadeysan, waa inaad ka saartaa liiska cad ee BIOS .

Sida loo saaro liiska cad ee BIOS

Sababtoo ah hadda magacyo badan, oo uu ku jiro HP, ayaa sheeganaya inay meesha ka saareen liiska cadeymaha BIOS , waa inaad awood u yeelatid inaad ku soo dhawaato adigoo cusboonaysiinaya BIOS -kaaga . Ogsoonow inaad soo dejiso software-ka BIOS -ka ee casriyeynta websaydhada iibiyaha kumbuyuutarka sida HP, Lenovo , iwm. – tusaale Lenovo System Uptade Tool, Kaaliyaha Taageerada HP, iwm.

Ma jirto si kale oo looga saaro liiska cad ee BIOS ilaa aad taqaanid xisaabta binary. Waxaa laga yaabaa inaadan awoodin inaad ka saarto liiska cad ee BIOS adiga oo iftiiminaya BIOS^{(flashing the BIOS)} . Dadku waxay codsiyo online ah u dirayaan Lenovo , tusaale ahaan, iyaga oo waydiinaya inay ka saaraan liiska cad ee BIOS^{(BIOS Whitelist)} , haddii ay jiraan. Waxaan fahamsanahay in HP uusan hadda abuurin liiska cad ee BIOS si aad si fudud u cusboonaysiin karto BIOS adigoo booqanaya hp.com .

What is a BIOS Whitelist? Explanation and removal.

In this post, we will discuss what a BIOS Whitelist is, what is its use, and how to remove it. In short, a BIOS whitelist is essentially a list of hardware approved for use in that computer – if you try to use anything else, the computer won’t detect it. OEMs use a BIOS whitelist for hardware so that they can restrict users from buying any other brand.

BIOS stands for Basic Input Output System. It is the part of computer system that checks the computer before loading the operating system loads. Some of the important functions of BIOS are:

1. Checking what all devices are attached to the computer. That list includes a mouse, keyboard, joysticks, etc.
2. Loading the device drivers and checking them for faults. The computer gives you an error message is any of the drivers is not available. For example, if the keyboard is not detected, it would say, “Keyboard Not Found”. This is before loading the operating system
3. It also manages RAM until the operating system takes over
4. After testing the boot device (HDD or DVD or Flash drive) for faults, it loads the elementary parts of OS into the RAM. From there, the operation system takes over.

What is BIOS Whitelist

A whitelist is generally a list of programs, software, and system files that are allowed on a computer. In case of a firewall, you might have already created a list of programs that can access the Internet. That is the firewall whitelist. BIOS Whitelist too works on similar lines.

If you add new hardware to your computer or replace old, damaged hardware, the computer will first check the BIOS whitelist to see if that particular hardware (brand, make, or model) is allowed.

Thus, BIOS whitelist is essentially a list of hardware approved for use in that computer. If you try to use anything else, the computer won’t detect it. You may ask why BIOS whitelist is required. The next paragraphs talk about of use of BIOS whitelist.

What is the use of BIOS whitelist

The intended use of BIOS whitelist is to see that the end users do not install any hardware that can cause conflicts with other hardware on the computer. The BIOS whitelist means a listing of what all hardware one can use on the computer without conflicting with existing hardware.

But that is so yesterday. The real purpose of BIOS whitelist, in my opinion, is to block hardware parts bought of any other model and brand. For example, if you buy a computer from XYZ brand, and want to add a Wi-Fi network card to it, you will have to buy only the ones whitelisted in BIOS. This pretty much means that brands are limiting your options so that you stick to the same brand as that of the computer you have.

Why users don’t like a BIOS whitelist

As discussed above, not all computer manufacturers are OK with people using any other brand of hardware on their computers. Hence, they enforce restrictions in the name of BIOS Whitelist. Even if you have compatible hardware such as a network card, you can’t use it if it is not listed in the BIOS whitelist. That is the main reason why people don’t want any BIOS whitelist.

If there is no whitelist in BIOS or if it turned off, users can use any hardware they want – with the original computer. To be able to install any hardware into a branded computer, you must remove the BIOS whitelist.

How to remove BIOS whitelist

Because now many brands, including HP, are claiming to have removed BIOS whitelist, you should be able to get around by upgrading your BIOS. Note that you have to download the BIOS upgrading software from the computer vendor’s websites like HP, Lenovo, etc. – e.g. Lenovo System Uptade Tool, HP Support Assistant, etc.

There is no other way to remove the BIOS whitelist unless you know binary mathematics. You may or may not be able to remove BIOS whitelist by flashing the BIOS. People are sending online petitions to Lenovo, for example, asking them to remove the BIOS Whitelist, if any. I understand that HP is no longer creating BIOS whitelist so you could easily upgrade the BIOS by visiting hp.com.
