System BIOS image for the HP Z400 Workstation, family code 7G3, version 03.60, compressed as a ZIP of about 925 KB. A file like this is used to restore a desktop board that no longer posts after a failed update or a corrupted flash, usually by writing the binary straight onto the SPI chip with an external programmer. Dump and keep the existing chip contents first, since they hold serial and configuration data, and check the extracted file size against the capacity of the flash chip fitted on your board.
