I'm able to boot 7.1R disc1 from sec master. I load 7.1R fixit livefs in the opposing drive, remove the 7.1R boot disc1 and insert 7.2RC-1 disc1. Then do dd | sha256 from fixit on the 7.2RC-1 disc1. Hashes match. I'm able to boot 7.1R disc1 from sec slave. I load 7.1R fixit livefs in the opposing drive, remove the 7.1R boot disc1 and insert 7.2RC-1 disc1.

Unfortunately I get NO output on the console when booting this disc1 so I'm at a loss. The drive lights up, after the drive's insert disc tasting sequence is complete and the disc is still spun up, so the system does read and try to boot something off the drive for sure. Then it silently passes to the bios/onboard netboot. The discs were written on the above writer. So I'm stuck... with cdrecord, installing 7.1R, copying in 7.2RC-1's loader and building RELENG_7. No big deal right :) If I have time, I'll do a RELENG_7 make relase and see what that disc1 does for me.
