BIOS archive for the HP Compaq 6005 Pro desktop, with the name indicating a 1 MB image intended for a flash chip of that capacity. Business desktops of this type keep their firmware on an SPI chip that can be reprogrammed with a programmer after a failed update or corruption. Confirm your chip is indeed 1 MB, because a size mismatch means the image will not fit. Reading and saving the original contents first preserves serial number and board-specific data that a generic dump may not carry.
