Thanks for the clarification and, yes, I'd be interested in having a look at
the new driver - if you don't mind sending it to me that would be great.

Karl seemed to be patching the firmware for some reason - I don't know why.
As Roman points out, the firmware is operating system independent.

I'm still a little unclear as to what actually can be done with the box at
the moment.  If the firmware loader (under Linux) is not ready, I'm unclear
as to what the RPM can do without the firmware.

At the risk of wasting your time with my questions (and drawing you away
from your work), when you say a "small command line program that enables the
RPM io box (which is on bypass mode by default)", does this mean that you
can plug in a mic/headphone and get them both amplified and sent/received
to/from the RME PCI board?  But if that's the case, I thought that was
really all the RPM box did anyway??

So, when you say "everything works as you would expect it", I'm a little
unclear how that would be the case without any firmware loaded??

Sorry, but it would be nice to know what can actually be done/not done as it
stands at the moment.

Regards, Martin
