      This is you clean file. Write to MX25L1605. According to the KRUG platform, pin EN is unused with the MAX17411 chip.

              Among the original files, only the file named MX25L1605_20170405_144925- ORIGINAL contains ME_REGION firmware. The file W25Q32_20170405_145047- ORIGINAL does not contain the ME-REGION part. I posted the file with the cleared ME-REGION in the post above.

                  [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,...

                  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...

                  Dell Latitude 5400 Chromebook UEFI bios
                  by jhanra
                  Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                  so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                  in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...

                  Intel Arc A380 videocard power limit remove - BIOS needed
                  by iulik17d
                  Hello everyone!
                  The Asrock A380 low profile card (ID 8086 56A5 - 1849 6006) have an power limit of 45W. Intel removed the possibility to increase power using the software utility, anyway the card is in an proxmox machine that doesn't run windows.
                  The same hardware is in another form by the name Asrock A380 Challenger that have the same VRMs and the power limit is at 60W. I searched online and found on another website an .bin bios file from the Challenger variant, that I flashed using an CH341a. Flashng worked well, I put the card in PC and booted. GPUz shows that new device ID is 8086...

                  Dell Precision T7910 no bios, no post after applying SAS/RAID setup
                  by bmxlovah
                  Hi,

                  My Dell Precision T7910 died after enabling onboard SAS controller and applying RAID settings. There were no hardware changes between working and not working state, only setup (via bios -> controller settings). After applying settings and reboot PC turns on, flash leds (normally) but there's no further action, it just stays on with no graphics and no keyboard led's on. There's no Dell logo, nothing. I've tried resetting bios by jumper, replacing cpu's, replacing ram, removed/replaced cmos battery, disconnecting all drives etc. I've also dumped .bins from mobo chips SLI1 (16...
