BIOS firmware for the HP ProDesk 600 G6 Mini desktop, read from a GigaDevice GD25SQ256 flash chip, in a 10.8 MB RAR archive. The GD25SQ256 is a 256 Mbit (32 MB) SPI memory, so the full dump should match that size. It is used to reprogram the chip with an external programmer when the PC is stuck with no post or a failed BIOS update. Back up the original chip first, as it stores the serial number and product data, and check that your programmer supports this flash part.
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.
