Just after the label loop: when it's trying to seek to the proper cylinder, there's code which looks like cur = ((RLADDR->rlmp&077700) >> 6) & 0177; or something close; the 077700 should be 0177700. In my driver I have all this stuff #defined, so I'm not exactly sure what you have. I'll send you my driver if you want it.
