                Not always.Sometimes a 2nd bios chip can be a recovery bios image.

                  Re: Toshiba c855-22m bios

                  i have programmed BIOS but no display again.
                  display chip is getting hot(AMD). i reheated it but nothing.
                  any suggestions!
                  when i measured coils i do get 0.9V on VGA coil and 5v on VGA port.
                  1.15V on CPU coil and 1.5v on Memory coil.
                  Thanks

                      [Problem/ Request] Bricked TongFang GK7MRFR BIOS
                      by cr4zychriss
                      Hello everyone,
                      I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
                      I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

                      ASUS Zenbook Pro Duo UX8402ZA BIOS
                      by pirati
                      Hello everyone,

                      I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                      When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                      I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                      by istvanszasz99
                      Product Name: Razer Blade 15 (2022)
                      Product ID: RZ09-0421
                      Motherboard: CH580
                      BIOS Versions I work with: 2.02 & 2.06
                      Bios File Size: 32,768 KB

                      Dear Forum Readers!

                      I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
                      I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
                      The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).

                      ASUS TP500LA BIOS request/repair/merge?
                      by jbonavita
                      Hi, my laptop wont boot at all
                      With original bios no POST, only LED lights
                      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                      Some issues
                      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                      B- If updated from 500LN version 203 to 300, the battery stops being recognized

                      Things I tried

                      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
