Do you have a PCI324 or 424 card?

A MOTU 2408 with the mkII interface.  I am using some drivers, from back
in 2004. However, I did 
load up the latest vista/XP 32 drivers for the latest MOTU with the
mkIII interface, and achieved 
the same results as previously described, with the older 2408 drivers.
