For anyone experimenting with this, one "quick and dirty" way to get into the bmminer.conf file without any heavy command-line work is to go to the antminer console, "system" tab, -> "upgrade" tab -> then generate an archive. Keep that safe but rename a COPY of it.
Open the COPY up with 7-zip or whatever, open up the bmminer.conf text file, change multi-version from "1" to something higher, save it.
Back to the antminer console, go to "restore backup". Select the archive file you just modified and restore it. If something goes wrong you can go back to the original settings by afterwards restoring the unmodified version of the archive.
So that's the way to do it with only basic knowledge and it works for me, including cloning my settings across multiple new miners.
I'm not saying it's the best way or even the easiest way. It works well for me.
Again, this is just one way you can access it.
EDIT: You can also access the file using WinSCP and Putty on a Win machine, but there's a bit of a learning curve if you're not familiar with it.
As Steve said, ASICBOOST is NOT working right now on the S9 via PH.
Going into any of these settings can brick your miner, so you need to accept that fact as your own risk and your own responsibility before you start.
