BIOS image for the Dell Precision Tower 3620 workstation, labelled as firmware version 2.21.0 and marked as fully working. The 7.93 MB RAR is meant for recovering a desktop board whose SPI flash is corrupted, for example after a failed update or a no-POST fault. Technicians write such a file with a hardware programmer on the board's flash chip. Dump the original first, since it holds the service tag and system-specific data, and confirm the image size fits the chip installed.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
