I erased the original contents (all FFs) of the bios file, since I thought it was garbage. However, the files I downloaded from this thread are all 16,384 Kb, where I need it for 8 Mb. How do you get this file to write to the chip if the size is too large?

The 25Q80CSIG is 8 Mega bits , not Mega Bytes. 8 Mega bits is 1MB (Mega Bytes) . You have made a mistake there and erased the wrong chip. The golden rule of bios programming is to always make a good backup. If you didn`t make one then you`ll need to find,or someone to post that 1MB dump to flash back to that chip. Post a picture of the area on the board where that chip is.

Apparently the Winbond W25Q128FWSQ 128M-bit (16MB) chip is the correct bios. I did take the motherboard to a local computer shop that wrongly indicated that the GigaDevice GD25Q80CSIG chip on the other side of the motherboard was the correct chip (see image). Coincidently, another GigaDevice 25Q80CTIG (8M-bit) chip is located near the Winbond chip on the front side of the motherboard. Thank you for clarifying the correct chip and size for me. Any help to revive the bios for the GD25Q80CSIG will be greatly appreciated.If you didn`t make one then you`ll need to find, or have someone post the 1MB dump to flash back to that chip. Post a picture of the area on the board the location of the chip.​

Recently used a Selek MLK AMD 19802-1 FGRDN$JA to confirm that that the GD25Q8OCSIG (8M-bit) chip is blank. I've attached the backup bios from my motherboard (Selek MLK AMD 19802-1 FGRDN$LA) to see if anyone could create a clean bios from the latest bios update (1.24.0). Thank you.

Hello!
I have a problem with a Dell G5 SE 5505 laptop that I hope someone can give me a few pointers on.
[OK, it's not really a laptop, I'm running the motherboard on my desktop with only cooling, RAM and an M2 drive attached.]
I had some performance issues, so I decided to update my BIOS from 1.7.0 to the latest version, 1.20.0.
The computer restarted and the update dit not want to continue without a battery connected, even though I used dell's method of bypassing this requirement.
I tried updating to a custom BIOS from Reddit user Satori_Nori https://www... -
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,... -
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...04-23-2025, 04:30 PM -
Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the...
