    Sorry for writing post-under-post.
    I have made a dump of my BIOS with Intel Flash Programming Tool. I think this one will be much more useful.
    BIOS .BIN file is in attachment
    Thank You

                                            I have a Dell Precision T1650 MT workstation (of the following spec.) that was bricked yesterday when attempting to update the BIOS from A27 to A28 per:

                                            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...

                                            [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 3660 Tower Workstation BIOS
                                            by cozily
                                            I bought a DELL Precision 3660 Tower Workstation from a second-hand seller. After bringing it home, I found out it was actually a testing unit. The BIOS cannot be upgraded (only the ME and PD2 sections are upgradable), and there are test messages displayed during boot, which really affects the user experience.

                                            Upon inspecting the motherboard, I noticed that the BIOS is composed of two chips: one 8-pin 16MB chip and one 16-pin 32MB chip.

                                            I acquired two new chips from another source containing the official BIOS version, but after installing them, I found that none of the...
