METHOD FOR UPDATING FIRMWARE OF AN ELECTRONIC DEVICE WITHIN A COMPUTER

摘要

A method for updating firmware of a hard disk drive (HDD) within a computer. In order to use the firmware that has been updated without rebooting the computer, the old identification information of the old firmware is loaded into a random-access memory (RAM) of the HDD. The new firmware containing new identification information is written in the non-volatile memory of the HDD during a power-on state of the computer. The new firmware containing new identification information is loaded into the RAM, and the new identification information is rewritten with the old identification information. The old identification information at the RAM of the HDD is sent back in response to a request of identification information from the operating system prior to cold boot.
