I assume all the same applies to the 2842? Is the driver actually the
same? And, should I get one of these jewels, should I immediately,
if not sooner, upgrade to 2.1-STABLE? Enquiring minds want to know!
A second question for the group: a few mail-order houses are carrying
the 2842 sans EZ-SCSI software, for about $40 discount. Other vendors
tell me they shouldn't be doing this. My local hardware house often
carries Adaptec kits w/o EZ-SCSI, but not in the 2842. Should I go
ahead and buy from these guys who don't feel it necessary to sell me
software I don't want or need? ;^)
