BIOS image for the HP Z820 Workstation, with J63 as the HP system ROM family and version 03.90 indicated by the 0390 tag in the name. The ZIP is 12.7 MB and contains a .BIN file suitable for reflashing the board's SPI flash when the official updater cannot be used. Before writing with an external programmer, read and keep a copy of the existing chip, because it holds serial and configuration data. Check that the binary size equals the chip capacity; an image that does not match will not fit.
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.
