I couldn't see anything on that link.
But I think you might have meant this.
prism2.lha1.6driver/net1152210K2006-06-23 Driver for 11Mbps wireless network cards - (readme)
I've read through the Doc (Best I could using a PC).
It lists a lot of the Orinoco PCMCIA cards, including one that I have (Orinoco Classic Gold).
But I'm pretty sure mines not Prism2 chipset. I think they changed over to Hermies from memory in the current manufactured batch.
Oh well, I'll keep searching EBay.
If anyone can advise a good cheap card thats suitable I'm all ears.
Doesn't have to be high powered or anything.
I also note that there are Prism 2.5 and Prism 3 standards. I have no idea weather these work also or not.
