I had it working at some point (I think it was in 6.1-current). During an upgrade/boot from bsd.rd, drop into a shell before beginning the upgrade, manually set numcpu (I think that was the variable name) to 2 (not sure why it gets set as 1).
After that, the upgrade script will “detect” two cpu cores and install the bsd.mp kernel. The last part is much more fuzzy to me. I think after the kernel re-linking, I would copy it to the FAT partition. That seemed to work, inasmuch as it did not throw any errors about kernel re-linking errors. It has been quite a while since I’ve performed an upgrade on my ERLs. I will try it out when I get a chance. > On Jan 13, 2018, at 03:01, Stefan Sperling <s...@stsp.name> wrote: > >> On Fri, Jan 12, 2018 at 11:24:59AM -0500, Scott Bennett wrote: >> After reading INSTALL.octeon, I was able to write miniroot62.fs to a usb, >> plug that into the ERL, and perform a normal installation.
