ABSTRACT:
In the case where a disk storing firmware for rewriting is used to upgrade firmware stored in a flash memory, byte codes #15, #16of the disk corresponding to a reserve code (byte codes #15, #16) of the flash memory are ignored. Specifically, byte codes #1to #14of the flash memory are compared with byte codes #1to #14of the disk. If all codes match each other, it is determined that the firmware of the disk is firmware of a compatible model and a rewrite operation is started. Therefore, under the condition that the disk device is of a compatible model, the firmware of the device can be upgraded and thus the firmware is improved in compatibility.
