Aha and indeed. In Justin's sequencer, one of the FASTMODE flags is FAILDIS. This would alter the value of just one bit, and might indeed cause a parity/crash. Maybe? I try it... and EUREKA! It WORKS! My system suddenly has two whole scsi devices. It promptly dies (possibly because of a timeout induced by the absurd delays I introduced), but I'll bet that if Doug and/or Patrick converts the middle FASTMODE flag to FAILDIS on an unhacked driver, it will magically work (or at least die further on). I'll try it myself in a minute, but I didn't save a particularly clean original (:-< and will have to put back the original and relayer the patches before making just the one change. rgb Robert G.
