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.

hello everyone and excuse my english
I just got a Dell G3 3579 CAL53 LA-611P REV 1.0 (A00) without the Bios Chip, and I installed a 16mb winbond and tried all the bios available on the forum but still there is no display, just the fans are running at maximum. and I tested all the components they seem good.

Got a dell latitude 5285 with motherboard version LA-D89 in the shop today which won't power on. So I opened her up, disconnected the battery and hooked up a charger to see if anything stands out on the board.

Anyone on here have the files laying around?
