            Here's the Bios bin. The bios IC is a Gigadevice. The Dell service tag is F5YHT44. Thanks again

                            It's a customer's laptop, and it's not stolen. And yes, the bios should be 64 MB, but the dump was only 8 MB. I'm not sure if this was due to the IC being 1.8v and my programmer being 3.3v. I did a manual read and save using NeoProgrammer as the IC couldn't be detected automatically by any of my software. I used the ch341a programmer which I have been told isn't great for newer ICs. I have a better programmer ordered the TL866II Plus. Is it possible to flash the IC with a clean bios bin? I have been on holiday hence the delay in replying. Thanks

                                      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, ๐Ÿ˜…๐Ÿ˜…๐Ÿ˜…...

                                      Hi

                                      i have dell latitude E7270 with following symptoms:
                                      - takes long time to restart.
                                      - sometimes powers on and then off
                                      - sometimes while working it just dies,

                                      From googling online bios clean could possible resolve this?

                                      i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)

                                      As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
                                      I reinstall...

                                      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...
