BIOS dump for the HP Compaq dc7800 desktop, with Grizzly and revision 0B mentioned in the name, likely the board code name and revision. The ZIP measures 1.74 MB. Such an image serves to rescue a system with corrupted firmware by programming the SPI chip directly using an external programmer. Before flashing, read the original chip and keep a copy, confirm the file size matches the chip capacity and check that the board revision matches, since HP business machines often hold serial and asset data inside the flash.
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.
