Firmware for the HP Compaq 6000 Pro business desktop, which the name reports as tested and working, provided as a 1.90 MB RAR archive. No board number or version appears, so confirm the motherboard is from the 6000 Pro line before using it. Technicians usually program such a dump onto the SPI chip with a CH341A or similar tool to recover a board that powers on without video. Back up the original contents first, then check that the extracted image length matches the flash chip capacity before writing and verify.
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.
