Backing-up of bios for Pioneer DVR-215

Dear all, i am currently in possession of a Pioneer DVR-215 optical drive. And i am threading on thin water to flash the bios, even patching the bios with a RPC region code lock. Thus i would like to safekeep a original copy of the current firmware located within my optical drive. Would it be possible to shine some light on the matter of using which software to perform the backup operation for my drive. Greatly appreciate any help rendered and hope to hear from you soon thank you.

It’s currently not possible to back up the firmware your drive came with. However, you can always download the original 1.18 firmware from the official Pioneer site as a backup:
