Updated driver for Megahertz PCMCIA card

I need to get updated NT drivers for my Megahertz XJEM3336 PCMCIA card for a laptop on my home network. Does anyone know where I can get such drivers. 3COM, who bought out Megahertz, does not provide such drivers anymore and they were never any help when the laptop had Win95 loaded on it and wanted DOS support. Anything out of the “ordinary” freaked 3COM out. Any help would be greatly appreciated.
