Firmware archive for the HP Z2 Mini G4 Workstation, supplied as a 10.7 MB RAR file. The name gives no board number, BIOS version or chip size, so open the archive and inspect its contents before use. Such dumps serve to recover a desktop whose BIOS is corrupted, typically by writing the SPI flash directly with a programmer like a CH341A. Always read and keep a backup of the existing chip first, and make sure the image size equals the flash capacity, otherwise it 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.
