Firmware archive for the HP Compaq DC7800 business desktop, RAR format, 1.61 MB. No BIOS version, board revision or chip type is mentioned in the name, so inspect the contents to learn whether it is a raw dump or a vendor update. Technicians use such images to recover a desktop that no longer posts by writing the SPI flash with a programmer. Since these systems can store serial and asset data in flash, verify that information after flashing. Dump the original chip first and compare image size with chip 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 @biosarchive. Enginerys does not host this file.
