    Dell Precision M4400 BIOS Request

    Laptop has firmware issues (EC and BIOS) with plans to replace both Chips.

    I already have the EC firmware extracted.... But the BIOS is very weird.

    Macronix MX25L3205D Chip. 4MB. That is the BIOS chip. I plan to flash a Winbond to replace it.


    Pin 1 (CS) and Pin 5 (MOSI) Broke off the SOIC-8. After Extraction (During it both pins were loose, desoldering is mandatory for Precision M4400 bios extraction)

    I extracted 5 different BIOSes that have incomplete headers using flashrom. (All 5 extractions are corrupt)

    I need a full dump. Rev A29. I would be very grateful if you could provide it.

      Update your Service tag and original dump image even if it is corrupted.

                      Dell Precision T1650 MT Workstation bricked after BIOS update
                      by trix11
                      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:
                      - https://www.dell.com/support/home/en...-t1650/drivers > Dell Precision T1650 System BIOS

                      - Dell Precision T1650 mid tower Workstation
                      - Xeon E3-1225 V2
                      - 32Gb PC3-12800E RAM
                      - 4Tb SATA HDD
                      - motherboard: Dell part: 0C3YXR CN-0C3YXR-72200-39C-01GR-A02

                      **Need Help Unlocking BIOS and Hard Drive on Dell Precision 5820 Tower**
                      by federalhouse
                      Hi everyone,

                      I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.


                      **Background:**

                      I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.


                      **What I've Tried So Far:**


                      1. I accessed                      ...

                      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...
