The 1542 is indeed faster and more widely supported, but!!!!! the 1542
will _not_ work on ISA systems with more than 16MB of RAM (this was
confirmed by Adaptec tech support).  Because of the RAM limitation
(which is due to the way bus-mastering works on the ISA bus), I
had to buy the slower, less expensive 1522 since I plan on having
more than 16MB soon.  The new line of ATI Graphic Pro's also have
the same problem -- and they require you to have TWELVE megabytes or
less.
