All of us here at Cyclades drew staws and I pulled the short one-- so
I get to reply to this post.  So here goes:

-------------------  WARNING!!!  Offical BS to follow!  -------------------

Cyclades is aware of several clones of our Cyclom-Y series.  Many of the
companies that made clones went out of business, but there is probably one
or two left somewhere.  

We've tested these cards with our standard diagnostic software and have 
found that they are all, um, "lacking".  Most of them had some type of 
bug or another.  Some of these bugs are very serious.  One bug we've
found would keep the board from working in 50% of all Pentium based 
machines.

We have never found a card that is 100% compatible with our cards.  
If any card operates with our drivers it's by coincidence only, 
since we've never tested a clone card that worked with all of our
drivers (and we're not just saying that :).

So...  Cyclades doesn't guarantee that our drivers work with a Non-Cyclades
board.  We also don't offer any technical support for non-Cyclades boards.

Anyone who has a clone of a Cyclades card and is dis-satisfied 
with it can email sales@cyclades.com.  We like to keep track of these
cards and, if possible, help out those few people who get burned by
counterfeits.  We currently don't have an upgrade policy for these
unfortunate people, but we might be persuaded into it...  :)

---------------------- End of offical BS ------------------------------

For legal reasons I cannot say anything more.  It's a shame when the 
legal system forbids us in bad-mouthing someone who really deserves
it!

Off the record:  Two of the problems that we've seen with the clone cards
has been with their ability to work with some Pentium machines and with
their IRQ handling.  Both of these would make it not work in your system.

I reccomend that you try to get in touch with their technical support.  When
you get frustrated with their "support", email our sales department and see 
what they can do to help.
