Re: Dell e5470 adp70 la-c831p bios bin
when restarting the pc freezes with black screen even before showing the dell logo. I have to turn off, unplug and try again
if I hold down the power button when the pc is frozen, the fan runs at maximum for a few seconds, then turns offLast edited by drdom; 03-06-2021, 09:17 AM.Comment

I just managed to complete the installation in raid mode, in ahci mode after the preliminary phase the pc restarts and freezes on the spinning dots. I have 2 e5470 with the same problem.
the bios that i flashed takes a long time to display the dell logoComment

try this bios.Based on your service tag number this one has AMT ,and the spec is a H cpu. This bios will work for the other with the same spec. If the other has a U cpu youll need a different bios for that .Comment

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.

in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, π π π ... -

Hi folks,
I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)
Steps I took:- Read BIOS with CH341a, verified hash twice
