Parallel _Downloading_ firmware to the 7I43 requires:
1. Parallel port with _EPP_ interface, V1.7 or V1.9
_Accessing_ HostMot2 via Parallel port requires:
1. Parallel port with _EPP_ interface V1.9 _only_
2. If you have older bit files, (not november of this year)
There may be a problem with accessing the card via EPP
if the 7I43 is USB powered.
