BIOS and EC firmware set for the Dell OptiPlex 980 desktop, with the name listing two Macronix flash parts, the 25L1606E and 25L6446E, suggesting separate images for each chip. The 3.45 MB RAR should contain dumps matched to those chips. Technicians use such files to revive boards with corrupted firmware or no power-on. Identify which image belongs to which chip by size, as a 16Mbit and a 64Mbit part take different images, and back up both original chips before reprogramming.
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.
