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.... -
