Kuphazamiseke i-BIOS noma i-UEFI Firmware Update kanye Nokubuyiselwa kwe-Motherboard Flashback

A power outage, accidental reboot, or Windows Update firmware push that cuts off at 47% during a motherboard BIOS or UEFI update is one of the most dreaded hardware failures in computing. Because the Unified Extensible Firmware Interface (UEFI) stored inside the motherboard's Serial Peripheral Interface (SPI) NOR flash chip is the very first instruction code the processor executes when you press the power button, initializing CPU microcode, voltage regulators, and DDR4/DDR5 memory training before the graphics card or SSD even wakes up, a corrupted BIOS image leaves the computer completely brain-dead. When you press the power button on a "bricked" motherboard, the fans spin, the RGB lights turn on, the debug LED gets stuck on CPU noma DRAM, and the monitor remains completely black (No Signal).

Despite how catastrophic a black-screen BIOS brick looks, your hard drives, SSDs, files, CPU, RAM, and graphics card are 100 percent unharmed, and you almost never need to throw the motherboard away. Nearly every modern desktop motherboard and business/gaming laptop includes at least one hardware-level firmware recovery mechanism, ranging from USB BIOS Flashback (which can reflash a motherboard with zero CPU or RAM response using a dedicated microcontroller on the rear I/O panel), to Dual-BIOS backup ROM switches, OEM Boot-Block Crisis Recovery hotkeys (Ctrl+Esc on Dell, Win+B on HP), or a $12 External SPI Flash Programmer (CH341A / Raspberry Pi flashrom) that reflashes the 8-pin BIOS chip directly.

Yenza lokhu manje

  1. Wait at least 15 full minutes before assuming a BIOS update is frozen or turning off the power. During modern AMD AM5 / AM4 (AGESA), Intel LGA1700 / LGA1851 (Management Engine / ME), and laptop EC (Embedded Controller) firmware updates, the screen intentionally goes completely black and the system reboots 2 to 4 times while flashing separate sub-chips and retraining DDR5 memory. Turning off the power bar during that 3-minute black-screen pause is the #1 cause of self-inflicted BIOS bricks.
  2. Understand that your files and Windows/Linux installation on your SSD or hard drive are 100% safe. A BIOS update only writes to a tiny 16 MB ku 64 MB SPI NOR flash chip soldered onto the motherboard. It never touches your NVMe SSD or SATA hard drives. (However, if you used Windows BitLocker or Linux LUKS with TPM 2.0 auto-unlock, reflashing the BIOS will reset the CPU's Firmware TPM fTPM / PTT Platform Configuration Registers, meaning Windows will ask you to type your 48-digit BitLocker Recovery Key on the very first boot after you fix the BIOS).
  3. Perform a Full Capacitive Power Drain and CMOS NVRAM Reset first. Half of all "bricked" motherboards after a completed BIOS update are not actually corrupted, their old CMOS NVRAM settings (such as an old XMP/EXPO RAM overclock profile or voltage offset) are simply incompatible with the newly flashed BIOS version, causing memory training to hang on a black screen. Unplug the AC power cord, remove the silver CR2032 coin-cell battery from the motherboard, bridge the 2-pin CLR_CMOS / JBAT1 jumper with a metal screwdriver tip for 30 seconds, reinstall the battery, and power on with only 1 stick of RAM installed in Slot A2.
  4. Look at the rear I/O panel of your desktop motherboard for a dedicated "BIOS Flashback" button (Flash BIOS / Q-Flash Plus). If your ASUS, MSI, Gigabyte, or ASRock motherboard has a tiny physical push-button on the back panel (or bottom edge of the PCB) next to a specifically outlined USB 2.0 port, you can recover a 100% dead BIOS in 6 minutes using nothing but a FAT32 USB thumb drive, even if the CPU cannot boot at all.
  5. If you are on a Dell, HP, Lenovo, or ASUS laptop that went black after a Windows Update BIOS push, plug in the AC charger and try the OEM Boot-Block Crisis Hotkey. Most laptops protect a tiny, read-only "Boot Block" area of the BIOS chip that wakes up when you hold a specific key combination (Ctrl + Esc on Dell, Windows + B on HP) while pressing the power button.
  6. When preparing a recovery USB flash drive on another computer, ALWAYS use a small (2 GB to 32 GB) USB 2.0 stick formatted strictly as FAT32 with an MBR (Master Boot Record) partition table. Motherboard hardware flashback controllers are tiny 8-bit/32-bit microcontrollers that cannot read NTFS, exFAT, noma GPT (GUID Partition Table) drives. Using a 128 GB exFAT noma GPT USB stick is the #1 reason USB BIOS Flashback blinks three times and fails.

Isinyathelo 1: Khipha "Izitini Zamanga", Setha Kabusha i-CMOS kanye Nokuqeqeshwa Kabusha Kwenkumbulo ye-DDR5

Ngaphambi kokuthi ucabangele ukuthi i-chip ye-BIOS yonakele, hlola ukuthi isibuyekezo siphumelele ngempela ekugcineni futhi ibhodi lomama limane linamathele kupharamitha ye-CMOS engahambelani noma umjikelezo omude wokuqeqeshwa kwenkumbulo ye-DDR5:

  1. Khipha intambo yodonga lwe-AC kumandla kagesi (noma khipha ishaja yekhompyutha ephathekayo).
  2. Bamba inkinobho yamandla yekesi le-PC phansi imizuzwana engu-15 ukuze ukhiphe inselele yenkokhelo yokulinda engu-5V kuma-capacitor ebhodi lomama.
  3. Khipha ibhethri lohlamvu lwesiliva lwe-CR2032 kusibambi sebhodi lomama (kumakhompyutha aphathekayo angenawo uhlamvu lwemali, khipha isixhumi sangaphakathi sebhethri ye-Li-ion ebhodini lomama imizuzu emi-2).
  4. Fushanisa izinsimbi ezimbili CLR_CMOS (JBAT1 / CLRTC) izikhonkwane kanye nethiphu eyisicaba ye-screwdriver imizuzwana engu-30.
  5. Susa zonke izinti ze-RAM ngaphandle kwenduku EYODWA esele endaweni eyinhloko (ngokuvamile DIMM_A2, indawo yesibili evela ku-CPU), futhi ukhiphe noma yimaphi amahabhu esibili e-USB noma ama-hard drive angaphandle.
  6. Buyisela ibhethri le-CR2032 phakathi, xhuma intambo yamandla e-AC, uvule i-PC, futhi UNGAYITHINTI IMIZUZU EMI-5 EGCWELE. Ku-AMD Socket AM5 (Ryzen 7000/9000) kanye nezinhlelo ze-Intel DDR5, ibhuthi yokuqala ebandayo ngemuva kwe-BIOS flash noma i-CMOS ecacile isebenzisa ukulandelana kwe-DDR5 Impedance kanye Nokuqeqeshwa Kwesikhathi* lapho DRAM I-debug LED ihlala iqinile ngokusawolintshi/ephuzi imizuzwana engu-90 kuya ku-240* ngaphambi kokuthi isikrini sikhanyise ngokuzumayo.

Isinyathelo sesi-2: Indlela Yokubuyisela Ideskithophu A, I-hardware USB BIOS Flashback (Ayikho i-CPU/POST Edingekayo)

Cishe wonke amabhodi omama webanga eliphakathi nendawo nasezingeni eliphezulu akhiqizwe kusukela ngo-2018 afaka i-microcontroller yehadiwe ezimele (evame ukubizwa ngokuthi i-Super I/O noma i-Flashback IC ezinikele) enikwa amandla ngokuqondile umzila we-+5VSB (5-Volt Standby)* wokuphakelwa kwamandla. Ngisho noma i-chip ye-BIOS eyinhloko isulwa ngokuphelele ibe nguziro, noma ingekho i-CPU noma i-RAM efakiwe nhlobo, lesi silawuli singakwazi ukufunda ifayela eliqanjwe ngokukhethekile le-BIOS kudrayivu ye-FAT32 ye-USB futhi silibhale liqonde ku-chip ye-SPI BIOS.

Impela ifayela le-USB BIOS Flashback yokuqamba kanye nenqubo yenkinobho ngophawu lwebhodi lomama

I-Motherboard Brand Igama Lesici Sokumaketha Umthetho Odingekayo Wokuqamba Kabusha Ifayela Le-USB Uyicupha kanjani iFlash Hardware I-LED Blink Behavior & Complete Signal
I-ASUS (ROG, TUF, Prime, ProArt) I-USB BIOS FlashBack Qalisa okufakiwe BIOSRenamer.exe ithuluzi ngaphakathi okulandiwe .zip folder (which renames the .CAP ifayela ebhodini ethize yekhodi enezinhlamvu eziyi-8 njenge R5E.CAP, SZ790A.CAP, noma TB650P.CAP) and place it in the root of the FAT32 USB stick. 1. Turn PC OFF (leave PSU rocker switch ON so standby power is active).
2. Insert USB into the rear port labeled BIOS.
3. Press and hold the BIOS FLBK button for 3 seconds until the LED blinks three times.		 LED blinks slowly, then speeds up as it writes (4 to 8 minutes). Success: The LED turns COMPLETELY OFF.
Failure: If the LED turns SOLID ON and stays lit, your USB stick is not MBR + FAT32, the filename is wrong, or it is in the wrong USB port.
MSI (MEG, MPG, MAG, PRO) Flash BIOS Button Rename the extracted BIOS file from the .zip archive to exactly MSI.ROM (all caps, make sure Windows File Explorer has "File name extensions" checked so you do not accidentally name it MSI.ROM.340) bese uyikopishela empandeni yenduku ye-USB ye-FAT32. 1. Turn PC OFF (PSU switch ON).
2. Insert USB into the outlined rear Flash BIOS USB 2.0 port.
3. Press the Flash BIOS Button once.		 Red/white LED next to the button starts flashing after -5 seconds and blinks continuously for 5 to 8 minutes. Success: The LED stops blinking, turns off, and the PC automatically reboots itself. (Failure: Blinks 2-3 times and stops, or stays solid red = incompatible USB drive or wrong filename).
Gigabyte / AORUS Q-Flash Plus Rename the downloaded BIOS file (e.g., B650AORUS.F31) to exactly gigabyte.bin (lowercase) and place it in the root directory of the FAT32 USB 2.0 drive. 1. Turn PC OFF (PSU switch ON).
2. Insert USB into the rear port labeled BIOS (usually red or white).
3. Press the Q-Flash Plus button on the rear I/O or bottom edge of the motherboard.		 The QFLED light flashes orange/red rapidly for 6 to 8 minutes. Success: The QFLED stops flashing and turns off (or system powers on).
ASRock (Taichi, Steel Legend, Phantom Gaming, Pro RS) BIOS Flashback Rename the extracted BIOS image file to creative.rom (noma PSPBIOS.IMG on select newer AMD AM5 boards, always verify on your specific ASRock board's Support -> BIOS page) and place it in the root of the FAT32 USB 2.0 drive. 1. Turn PC OFF (PSU switch ON).
2. Insert USB into the specific rear USB port outlined for BIOS Flashback.
3. Press the BIOS Flashback Switch for 3 seconds.		 The LED begins blinking green. Wait 5 to 8 minutes until the green LED stops blinking completely. (Failure: If the LED turns solid green, the USB stick is not MBR/FAT32 or the file was not found).

How to format a guaranteed-compatible MBR + FAT32 USB stick (Fixes 90% of Flashback failures)

Modern Windows 10/11 refuses to format drives larger than 32 GB as FAT32 in the standard GUI, and almost all new USB sticks ship initialized as GPT (GUID Partition Table) esikhundleni se MBR (Irekhodi Eliyinhloko Lebhuthi). I-Hardware BIOS Flashback chips izokwenqaba idrayivu ye-USB ye-GPT.

Run these exact commands in an Administrator Command Prompt (Windows) on a healthy computer to convert any USB drive (ideally an older 8 GB or 16 GB USB 2.0 stick) into a strict MBR + FAT32 recovery stick:

:: Open Command Prompt as Administrator and launch diskpart
diskpart

:: 1. List all disks and CAREFULLY identify your USB flash drive number (e.g., Disk 2, verify by size so you NEVER select your main C: drive.)
list disk

:: 2. Select your USB flash drive (replace X with your USB disk number)
select disk X

:: 3. Wipe the drive and convert the partition table strictly to MBR (Master Boot Record)
clean
convert mbr

:: 4. Create a small 4096 MB (4 GB) primary partition (so FAT32 works even on a 64 GB stick) and format as FAT32
create partition primary size=4096
format fs=fat32 quick
active
assign
exit

Now copy ONLY your renamed BIOS file (MSI.ROM, gigabyte.bin, creative.rom, or your ASUS .CAP file) to the root of that new drive letter, safely eject it, and run the hardware Flashback procedure above.

Step 3: Desktop Recovery Method B, Dual-BIOS Switches and Boot-Block Auto-Recovery

What if your desktop motherboard does not have a rear USB BIOS Flashback button? Check whether it uses one of these two built-in fallback designs:

1. Physical Dual-BIOS Switch (BIOS_SW / M_BIOS & B_BIOS)

Many Gigabyte, EVGA, MSI GODLIKE/ACE, ASRock Aqua/Taichi, and AMD/Intel workstation boards solder two physical SPI BIOS chips onto the PCB: a Main BIOS (M_BIOS) and a Backup BIOS (B_BIOS). * If your board has a physical 2-position slide switch (BIOS_SW1): Flip the power supply off, slide the physical switch from Position 1 (Main) to Position 2 (Backup), and power the PC on. It will boot immediately off the healthy second BIOS chip. * Pro Tip to Repair the Bricked Chip #1: Once you have booted into the BIOS Setup screen (Del / F2) using healthy Chip #2, go to the M-Flash / Q-Flash / EZ Flash utility, load your BIOS update file from a USB stick, carefully flip the physical BIOS_SW switch on the motherboard back to Position 1 while the PC is still powered on at the Flash screen (only on boards without single-BIOS lock switches), and click Start Flash to overwrite the corrupted Chip #1. * If your Gigabyte board has DualBIOS without a physical switch (Soldered M_BIOS + B_BIOS): How do you force a switchless Gigabyte board to copy B_BIOS over M_BIOS when its automatic detection fails to kick in? 1. Turn the PC completely OFF. 2. Press and hold BOTH the case Power Button AND the case Reset Button simultaneously for 10 full seconds, then release both buttons. (Alternatively, hold the Power button down until the PC turns on and immediately shuts itself back off again, then press Power once normally). 3. This hardware power-interruption signal triggers the DualBIOS controller, bringing up a blue/black screen that says "Main BIOS is corrupted. The system will recover from Backup BIOS" and automatically reflashes the main chip.

2. ASUS CrashFree BIOS 3 / ASRock Boot-Block USB Auto-Read

Even on budget ASUS Prime or ASRock boards that lack a dedicated Flashback button, the first 64 KB of the BIOS chip is often a write-protected Boot Block (ASUS CrashFree BIOS 3): 1. Prepare an MBR + FAT32 USB 2.0 stick using the diskpart commands above. 2. Put the renamed BIOS .CAP file (using BIOSRenamer.exe for ASUS) AND a second copy with the original unrenamed .CAP filename in the root of the USB stick. 3. Plug the USB stick into a rear motherboard USB 2.0 port (black port nearest the PS/2 or top of the rear panel, never a front-panel case port). 4. Turn the PC on and wait 3 to 5 minutes. Even if the monitor stays black for the first 60 seconds, watch the activity LED on your USB thumb drive: if the Boot Block is alive, it will automatically scan the USB stick, locate the .CAP file, and launch EZ Flash to restore the firmware.

Step 4: Laptop BIOS Recovery, Dell, HP, Lenovo, and ASUS Crisis Boot-Block Hotkeys

Laptops are far more vulnerable to sudden BIOS interruptions than desktops because Microsoft Windows Update routinely pushes "System Firmware" updates automatically via UEFI Capsule Updates during a normal Windows restart. If a user closes the laptop lid or forces power off while the screen says "Please wait while we install a system update," the laptop bricks.

Thankfully, major laptop OEMs isolate an un-erasable Crisis Recovery Boot Block inside the Embedded Controller (EC) or Intel Management Engine / AMD PSP that responds to a secret key chord on power-up:

1. Dell Laptops & Desktops (Inspiron, XPS, Latitude, Precision, Alienware), Ctrl + Esc

Dell's built-in BIOS Recovery 2 / 3 stores a hidden backup copy of the BIOS image (BIOS_IMG.rcv) inside the hidden EFI ukwahlukanisa ku-SSD yakho yangaphakathi (noma ungayifunda ku-FAT32 USB stick): 1. Khipha ishaja ye-AC kukhompuyutha ephathekayo yakwa-Dell. 2. Cindezela bese ubamba Ctrl + Esc kukhibhodi ye-laptop eyakhelwe ngaphakathi. 3. Ngisabambe Ctrl + Esc, xhuma ikhebuli yeshaja yamandla e-AC kukhompuyutha ephathekayo. 4. Qhubeka ubambe Ctrl + Esc imizuzwana emi-5 kuya kweyi-15 kuze kube yilapho ukukhanya kwekhibhodi kukhanyisa noma kuvele Isikrini Sokubuyisela I-BIOS ye-Dell esibonisini (uma ikhompuyutha ephathekayo ingazikhanyi ngokuzenzakalelayo lapho ixhuma i-AC, cindezela inkinobho Yamandla kanye ngenkathi ugcina. Ctrl + Esc ibanjwe phansi). 5. Khetha okuthi Buyisa i-BIOS (noma Setha kabusha i-NVRAM uma inikezwa kuqala) bese ucindezela u-Enter. * Kuthiwani uma i-SSD yangaphakathi ingenalo ifayela lokutakula? Kwenye ikhompuyutha, yiya ku dell.com/support, faka I-Service Tag yekhompuyutha yakho ephathekayo, landa i-BIOS yakamuva .exe ifayela, gijima BIOS_Update_File.exe /writehdrfile noma uqambe kabusha okulandiwe .exe / .rcv ifayela ku-BIOS_IMG.rcvkwe a FAT32 Induku ye-USB, xhuma induku ye-USB kukhompuyutha ephathekayo ye-Dell eyenziwe ngezitini, bese uphinda futhi Ctrl + Esc inqubo.

2. I-HP Laptops & Desktops (Pavilion, Envy, Specter, EliteBook, ProBook, Omen, Victus), Windows + B

I-HP's Isiqalo Esiqinisekile / I-Crisis BIOS Recovery isebenza ngokufanayo: 1. Vula ikhompyutha ephathekayo ye-HP**** ngokuphelele bese uxhuma i-adaptha yamandla ye-AC. 2. Cindezela bese ubamba i-Windows Key + B kanyekanye (kwamanye amamodeli amadala we-HP, zama Windows Key + V uma Win + B ayiphenduli). 3. Ngisabambe Windows + B, cindezela bese ubamba Inkinobho Yamandla2 kuya kwemi-3 imizuzwana, bese ukhulula Inkinobho Yamandla ngenkathi uqhubeka nokubamba Windows + B enye imizuzwana engu-10 kuya kweyi-15*. 4. Isikrini sizohlala simnyama amasekhondi angu-30 kuya kwangu-60, i-Caps Lock LED ingase icwayize, ifeni epholile izophenduka phezulu, futhi isikrini i-HP BIOS Update / Crisis Recovery sizovela futhi sibhale kabusha ngokuzenzakalelayo i-BIOS eyonakele kokufihliwe. HP_TOOLS Ukuhlukaniswa kwe-EFI. *Uma okwangaphakathi HP_TOOLS ukwahlukanisa akukh:Landa i-HP BIOS SoftPaq .exewenye i-Windows PC, sebenzisa ifayela le- .exe isifaki, khetha "Dala i-USB flash drive Yokubuyisela," xhuma leyo drayivu ye-USB kukhompuyutha ephathekayo ye-HP, bese uphinda Windows + B + Amandla.

3. AmaLaptops eLenovo (ThinkPad, IdeaPad, Legion, Yoga), Fn + R

  1. Amakhompyutha aphathekayo amaningi esimanje e-ThinkPad kanye ne-Legion afaka i-BIOS eyisipele yokuziphilisa eqalisa ngokuzenzakalelayo uma ukhipha i-adaptha ye-AC, ufaka isiqeshana sephepha esiqondile "Embobeni Yokusetha Kabusha Okuphuthumayo" ngaphansi kwekhompuyutha ephathekayo imizuzwana engu-15, linda iminithi elingu-1, uxhume amandla e-AC futhi uyivule imizuzu engu-3, bese uyivula yodwa imizuzu engu-3).
  2. Nge-Fn + R Crisis Mode* kumamodeli asekelwayo e-Lenovo: Fometha induku ye-USB 2.0 njenge FAT32, khipha okuluhlaza .bin / .fd / .cap Ifayela le-BIOS eliphuma kungobo yomlando yesibuyekezo se-BIOS kaLenovo kunduku ye-USB, xhuma induku ye-USB neshaja ye-AC kukhompuyutha ephathekayo evaliwe, ubambe Fn + R (noma Fn + B), bese ucindezela Inkinobho Yamandla kuze kube yilapho i-USB stick LED iqala ukucwayiza ngokushesha.

Ukuvimbela izinhlekelele ze-BIOS ezizayo

Uma uhlelo lwakho selusebenza futhi, sebenzisa le mithetho emine ngaphambi kokuba i-firmware ikhanyise ngokuzayo:

  1. ** Ungalokothi Ubuyekeze I-Motherboard BIOS Kusuka Ngaphakathi kweWindows (ASUS Armoury Crate, MSI Center, Gigabyte Control Center):** Amasevisi angemuva e-Windows, izishayeli ze-antivirus, noma i-BSOD engazelelwe ingamisa isistimu yokusebenza phakathi ne-flash. Njalo kopisha ifayela le-BIOS ku-a FAT32 Induku ye-USB, qalisa kabusha kwendabuko I-BIOS Setup Utility (EZ Flash / M-Flash / Q-Flash / Instant Flash), bese uqalisa isibuyekezo ngaphakathi kwendawo encane ye-UEFI.
  2. Khubaza i-Windows Update Automatic "I-Optional Driver / Firmware" Iphusha Kumakhompiyutha Nakumakhompyutha Aphathekayo Angokwezifiso: Ukumisa isibuyekezo se-Windows ekukhanyiseni ngokungalindelekile i-UEFI capsule yakho yekhompuyutha ephathekayo noma yedeskithophu ngesikhathi sokuqalisa kabusha ngaphandle kokukucela, vula *Isiphathi Sedivayisi -> I-Firmware -> I-Firmware Yesistimu -> Chofoza kwesokudla -> - Khubaza I-Computer Configust * Izifanekiso -> Izingxenye ZeWindows -> Isibuyekezo SeWindows -> Phatha izibuyekezo ezinikezwa ku-Windows Update -> Ungafaki abashayeli abane-Windows Updates).
  3. Setha kabusha ama-Overclocks (Load Optimized Defaults) NGAPHAMBI Kokuchofoza I-Flash: Ungalokothi ukhanyise i-BIOS entsha ngenkathi usebenzisa i-CPU engazinzile i-undervolt noma i-DDR5 RAM overclock enolaka. Uma i-RAM iphonsa iphutha elilodwa elincane ngenkathi inciphisa isithombe esisha se-BIOS kumemori, ingalenga i-flash utility. Cindezela njalo F5 / F7 (Layisha Okuzenzakalelayo Okuthuthukisiwe), qalisa kabusha ku-BIOS ngesivinini sememori yesitoko se-JEDEC, bese usebenzisa isibani.

Imibuzo ejwayelekile ukubuzwa

Ngemuva kokuthi ngithole i-BIOS yami eyenziwe ngezitini, Windows 11 manje ikhombisa isikrini esiluhlaza okwesibhakabhaka sicela "i-48-Digit BitLocker Recovery Key" futhi ngeke iqale, kwenzekeni?

Akukho okungalungile nge-SSD yakho noma amafayela. Windows 11 isebenzisa isici sokuvikela ngaphakathi kwephrosesa yakho ebizwa ngokuthi **I-Firmware TPM 2.0 (`AMD fTPM` noma `Intel PTT`)** ukuze uvule ngokuzenzakalelayo i-BitLocker-encrypted C yakho: shayela kuyo yonke ibhuthi evamile. Ngoba ukukhanyisa kabusha noma ukusetha kabusha i-BIOS yebhodi lomama kushintsha izilinganiso ze-cryptographic hashi ngaphakathi kwe-TPM chip's Platform Configuration Registers (`PCR 0 / PCR 7`), i-TPM iyenqaba ukunikeza ukhiye wokuvula ngokuzenzakalelayo uze ufakazele ukuthi ungumnikazi wangempela kanye. Ku-smartphone yakho noma kwenye ikhompyutha, ngena ku-**`https://aka.ms/myrecoverykey`** Nge-Akhawunti ye-Microsoft oyisebenzisele ukusetha i-Windows, thayipha inombolo enezinhlamvu ezingu-48 esikrinini se-BitLocker esiluhlaza okwesibhakabhaka, futhi i-Windows izoqala ngokujwayelekile futhi ibuyekeze izilinganiso ze-TPM ngokuzenzakalelayo.

I-PC yami ingene esikrinini se-BIOS ngemva kokululama, kodwa manje ithi "Ayikho Idivayisi Esebenza Ngohlelo Etholiwe" futhi ayikwazi ukubona i-Windows SSD yami, ingabe isibuyekezo se-BIOS sasula idrayivu yami?

Cha, isibuyekezo se-BIOS asilokothi sisule isigcinalwazi sakho noma i-SSD. Esikhundleni salokho, ukukhanyisa kabusha i-BIOS kusetha kabusha zonke izilungiselelo zebhodi lomama emuva kokumisiwe kwamanje kwefekthri, okushintshe ukulungiselelwa okukodwa kwezimbili zesitoreji kusukela endleleni ukufakwa kwakho kwe-Windows kwalungiselelwa ngayo ekuqaleni: **(1) UEFI vs. CSM (Legacy Boot):** Uma wafaka iWindows eminyakeni embalwa edlule komdala. `MBR` Ithebula le-partition, i-BIOS entsha yenziwe ngokuzenzakalelayo `UEFI Only` (esithela `MBR` abashayeli); iya kokuthi **Qalisa** ithebhu ku-BIOS bese uvula **CSM (Imojula Yokusekela Ukuhambisana)**. **(2) Intel VMD / RAID vs. AHCI:** Kumabhodi womama we-Intel 11th-to-14th Gen, izinguqulo ezintsha ze-BIOS zivame ukuzenzakalelayo **Idivayisi Yokulawula Ivolumu ye-Intel (VMD) / RST RAID** ukuze `Enabled` (noma `Disabled` uma uke wayisebenzisa ngaphambilini); ukuguqula **Isilawuli se-Intel VMD** noma ukushintsha **Imodi ye-SATA** phakathi `AHCI` futhi `RAID` izokwenza i-Windows Boot Manager yakho ivele futhi ngokushesha.

Kungani ukukhanya kwe-USB BIOS Flashback ngemuva kwebhodi lomama kucwayiza izikhathi ezi-3 bese kuba bomvu/okuluhlaza okuqinile ngaphandle kokubuyekeza?

Iphutha lokucwayiza okungu-3 kanye nokukhanya okuqinile ku-ASUS, MSI, Gigabyte, noma i-ASRock BIOS Flashback isho ukuthi isilawuli sezingxenyekazi zekhompuyutha sinikwe amandla, sabheka imbobo ye-USB, futhi **ayikwazanga ukufunda ifayela**. Ezimweni ezingamaphesenti angama-95, lokhu kwenzeka ngesinye sezizathu ezintathu: **(1) Induku yakho ye-USB ifomethwe nge `GPT` itafula lokuhlukanisa noma `exFAT`/`NTFS` uhlelo lwefayela** esikhundleni sokuqina **`MBR` (Irekhodi Lokuqalisa Okuyinhloko) + `FAT32`** (sebenzisa i- `diskpart` `clean` futhi `convert mbr` imiyalo eSinyathelweni sesi-2 ngenhla yokulungisa lokhu); **(2) Usebenzisa induku yesilawuli yesimanje ye-USB 3.1/3.2 edonsa i-init yamanje kakhulu noma ehluleka ukubala kwe-USB 1.1/2.0** (zama endala, eshibhe kakhulu engu-4 GB kuya ku-16 GB USB 2.0 idrayivu yesithupha ekhabetheni lakho); noma **(3) IWindows ifihle isandiso sefayela** ngakho lapho uqamba kabusha ifayela ukuze `MSI.ROM`, empeleni kwaba `MSI.ROM.340`.

Ngingakwazi ukwehlisela (ukubuyisela emuva) enguqulweni ye-BIOS endala ngisebenzisa i-USB BIOS Flashback uma isibuyekezo esisha se-BIOS siphula ukuzinza kwami kwe-RAM?

Cishe kuzo zonke izimo, yebo. Ngenkathi isisetshenziswa sesikrini se-BIOS (`EZ Flash` / `M-Flash`) ngezinye izikhathi ivimba ukwehliselwa enguqulweni endala ye-BIOS uma ngabe i-AMD AGESA noma i-Intel Microcode amafuse ezokuphepha aye abuyekezwa, inkinobho yehadiwe **USB BIOS Flashback** kuphaneli engemuva ivala yonke i-SPI flash chip eluhlaza isuka ku-zero yomkhakha, okukuvumela ukuthi ubuyele emuva kunoma iyiphi inguqulo ye-BIOS endala esekelwa isizukulwane sakho se-CPU.
