Not all EISA machines are created equal you know. I also cannot guarantee that the diagnostic code in there is up to date. I've been running without it enabled for some time now. > aha1: target 0 refusing synchronous negotiation - using asynchronous transfers > aha1: no active SCB for reconnecting target 0, channel - issuing abort Unless you know aic7xxx assembly, I think you might find this difficult. It may be that there are still problems in the way we recieve and respond to SDTR, WDTR or REJECT messages, but those problems will most likely reside in sys/gnu/misc/aic7xxx/aic7xxx.seq. The error message you report is the result of the target reconnecting to the host when it hasn't disconnected first (or so the aic7xxx things). I have no idea how bounce buffering could have affected this unless you have a DMA problem. > I will nose around in the code later today and see if I can find the bad boy. > > later > mark.h -- Justin T.
