Apologies if this is the wrong forum, but I'm not looking for a specific BIOS file, I'm trying to understand how one makes a clean BIOS file. So here's the background. I have 2 HP EliteDesk 800 g2 mini 35w pcs. One is working fine; the other doesn't have display out or working USB's nor does it have any flashing error lights. The CPU does get worm enough to cause the fan to spin up, so I think it's posting, but I just don't know. I had it working at one point but trouble started when I tried to put in a drive caddy that had a cooling fan on it. I thought it would be compatible but wasn't... -

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,
So i've bough a ch341 programmer, and the chip was CH341B . the test clamp was not working( when connecting bios using test clamp, ch341 device was disconnecting) I tried soldering the bios on the provided board, soldering the bios I could read the chip but could not write or erase. ASprogrammer , neo, ch341a programmer... all programmer software was hanging and device was disconnecting after few second of erase/write operating.
So then I have soldered a capacitor(whatever I had..[10v ~470uf ] ) from VCC to GND on my provided pcb where you solder the bios
now all...
