BIOS or firmware dump labelled 620 INTEL, the second copy of that name, with no file extension and a size of 2.00 MB. The Intel token suggests the image belongs to the Intel-platform version of a 620 model, but no brand, board number or revision is stated. Treat it as a raw SPI image for a 16 Mbit chip. Confirm the board number on the PCB before flashing, dump the original chip as a backup, and check that your programmer detects the correct flash part and capacity.
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 →
