Working BIOS image for the HP DX 7800P business desktop, packed in a RAR archive of 1.60 MB; no version or board number is stated in the name. Technicians use dumps like this when a machine shows no display or fails to start after a corrupted update, and program the SPI chip directly with an external programmer. Save the original chip contents first, since HP stores serial and system data in flash, and check that the image size matches the chip before writing it.
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.
