    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.
