Mplus does not require any NT4 drivers.

for laptops running Softex or Card Wizard, the card should be recognised on insertion.  For others (some IBM Thinkpads), plug and play is not supported, and the PC must be booted with the Mplus card already inserted.

The card will show under 'modems', although it is clearly not a modem.

Any problems please call Tim Robinson +44 1256 790472 or Mark Maplethorpe on +44 1256 790616
