Sony DRU540 firmware

OK,

I got my next to free Sony DRU540A and put it in the kids machine. It burns good like my DRU500A but there is a few things. like media support.

  1. Who makes this drive, it’s not Lite-ON I have tried DVDinfoPro and Lite-on’s bitsetting tools and no go.

  2. Is there a way I can find the manufacture and use the manufactures firmware?

It’s an Optorite, not a Litey.

Look at www.rpc1.org and click on the “Download firmware” link on the left. Select the 540A, and it will give you the exact Optorite model number.
