Status register value of 2 bytes saved next to the second copy of the 440 G4 flash read. Programmer tools write this small file to record the chip protection and configuration bits present at read time. It contains no BIOS code and is only meaningful paired with its matching 16 MB image. When restoring the dump, it lets the original register state be reapplied. Otherwise it can simply be archived with the image, since flashing the main file does not require it on most programmers.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
