Fortunately, there are three documented (!) in the manual but, of course, I only want one. If I use "master slot 1" it won't boot. If I use either slot labelled "master slot 0", it will but then it won't talk to the ethernet card (WD8013EPC, 0x280, 5, 0xd8000) :-( It simply hangs in (NFS) mounting some shared directories. If, however, I replace the 2842 with a Buslogic 542B (ISA) and reboot with an older version of -stable, it will fly quite happily even if strangled on disk I/O. I am assuming that a cache problem would exhibit some symptoms with this card as well. I'm just about to build a "new" version of -stable with the aha driver in it to see if it exhibits the same symptoms .. michael
