BIOS firmware for HP 285 Pro G1 and G2 microtower desktops, supplied as a 2.55 MB RAR archive. The name gives no board number or version, so confirm the motherboard and chip before use. Images like this are written to the SPI flash chip with a hardware programmer to recover from a failed update or corrupted firmware. Always read and store the existing chip contents first, since they may carry serial and product data, and verify that the image size exactly equals the capacity of the installed flash chip.
