RPC1-only firmware for Optiarc AD-5670S

Would it be possible to get a patched firmware for Optiarc AD-5670S (2AHI) with only the rpc1 patch, i.e. 2ahi_rpc1.zip without the riplock patch? There seems to be no “slow” patched firmwares available for this drive.

Or, is there any other way I could make my 2009 Mac Mini DVD drive rpc1 while keeping it low-noise?

Thanks!

It’s here now. Just did a quick patch.

Excellent, works like a charm. Many thanks.
