    [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 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...
