    Eprom and bios

    I have a card of a brother mfc l2700 dw multifunction on which I think the eproms are blown (it mounts 2) 1= gd25q40bt and another gd25q128csig, the questions are: do I have the chip disp. the 1 is the same and for the 2 I have gd25q127csig is it okay the same? Or you can provide me other mods. comp.?

    Another question for the bios to write on it online I can't find anything but I both took the bios from a card of the same multifunction, only that it had different chips, i.e. w25440clnig and w25q64fvsig, I ask that the bios will be the same and therefore I can insert them on my new chips?

    Finally, to look at the perfect compatibility, should the abbreviations be looked at in their entirety or is it just the first 2 numbers, the central letter and the following 2 numbers? Thank you with all my heart.

      first 2 numbers are the interface, second set of numbers is the capacity < very important.
      final letters also important because they indicate stuff like voltage.

          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...

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          by Wahaz
          Hello,

          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
          So I thought it was a Bios problem.
          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

          [HELP] G712LWS BIOS capsule
          by TraJikar Mac
          I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
          The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

          You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

          Also, I uploaded a backup file for the bios that I extracted by using CH341A...

          Dell 9010 MT BIOS Update Always Fails
          by mikeybass
          Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...
