I also have a Miro to be precise I have a Crystal 32S
I use the Metheus premier drivers from the vibrant list for about 1 year know
and never had any problem with it for the PAR.
You could also use some of the s3 drivers or try some others a lot of those
cards have s3 chips.
BTW the ADI provided with my Miro is not good, and they were not helpful on
this in there forum, the person representing them seems to be rather ignorant
about 3DS.
However all the other drivers are great.
