| Well, this problem actually has nothing to do with the 2091 per se, it's
| a bug in the Western Digital SCSI chip used for both 2091 and A3000.
| The last revision of the SCSI chip had bugs that broke reselect
| capability at the high level of software, so the A2091 and A3000 SCSI
| drivers solved the problem using low level commands.  The new release of
| the chip fixed the high level commands but broke the low level commands.

    Which chip is this, Dave? Is is the WD33C93 the same as in the A2090(A)?
 I wonder because I have seen reports of reselection problems in the 2090.
 If so, which chip revision is ok? which not?

    PS.
    I gotta comment on your .sig. You know the old Newton line, If I have
 seen further than others, it is because I have stood etc; but did you ever
 catch the Murray Gell-Mann version? If I have seen further than others,
 it is because I am surrounded by dwarfs.
    Kinda gives hubris a whole new stature.
