Combined BIOS and EC firmware for the Dell Latitude XT3, board code Patron, with motherboard number 6050A2530301-MB-A01 following the Inventec pattern. Having both images matters, because a faulty embedded controller dump can keep the laptop from powering on even with a healthy BIOS. The 5.04 MB ZIP should be unpacked and each file written to its own chip with a programmer. Read and save the originals first, check that the board number and A01 revision on the PCB match, and confirm each file size suits its chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
