   I've never used them with my board, but I do know that Adaptec
   themselves are apparently selling them and supporting them as an
   alternative to the ASW-410 package.  You might want to try calling
   Adaptec support and asking them whether they'll work with the EISA
   boards in Enhanced Mode and such, or whether they're just supporting
   them for the 154x series boards.

AHA-174x boards (at least the one I have, and others at that rev) don't
work properly in Standard Mode (compatible with 154x and 164x) doing
1024-byte read/write operations, or some such thing.  Apparently once
in a while stale data is read; maybe a similar problem happens on writes,
maybe not.  This caused me lots of lost usage on my 486/33 running Linux.
The workaround in Linux was to do 512-byte I/O on AHA-174x boards in
Standard Mode, just as DOS does (apparently).  Now Linux supports Enhanced
Mode, so I'm just waiting for the right diskette to arrive in the mail
so I can switch my AHA-1740 to Enhanced Mode, which apparently works fine.

So, maybe that's the problem the Corel stuff had -- doing 1024-byte reads
(or maybe any value other than 512 bytes) from an AHA-174x in Standard Mode.
