2.9.1 BSD on 11/34 + sc21-bm + fujitsu m2333k

Exciting stuff for a Friday night, right? Here's a visual aid in case you're needing further inspiration: https://www.instagram.com/p/_K-zHhHvLn78Qu5ijWqMf-HBem1LKMLaEdI1c0/ The M2333K is the smaller one on the left with the green and yellow lights on. I'm booting from rl0, which contains the tuhs 2.9.1 rl02 image I wrote with vtserver earlier. I want to use my nice, roomy smd disk so I can pull in all the sources and recompile stuff and I've managed to get this *so* close to working but I'm getting xp0a: hard error bn xxxx cs2=1100 <MXF, IR> er1=0 on every single block when I try to mkfs /dev/xp0a 4800 This disk was working fine years ago via MSCP attached to the 11/73 (before I lost the Micro/11 power supply). Anyway, I referred to http://bitsavers.trailing-edge.com/pdf/emulex/SC2151001-CC_SC21tech_Jan87.p… to set the emulation on the Emulex card for two rm03s and they're showing up in xxdp's zrmlb1 formatter, though they won't format there, screensful of errors. I think I set the m2333k to 32 sectors, per this manual: http://manx.classiccmp.org/collections/antonio/chrisq/B03P-4760-0101A_-_M23… Because XXDP is reputed to be really strict, I figured that was normal and then tried the Emulex on-board formatting procedure against both xp0 and xp4 and they formatted perfectly without error. Guess the Emulex on-board stuff doesn't bother verifying much? So I think that maybe I've misunderstood the hard sectoring / sector sizing thing. Does anyone remember the gist of it and would you be able to describe? Do you see any other mistakes? thx jake
