[plug] Problem with NE2000 card using thin coax.

[Rob Hall]

David,

If they have a Realtek chipset (an aweful lot are), I might just have the
drivers you need.  I could probably email them to you, or if you like you
could pick them up from here since I'm not that far from you.

Regards,


Rob Hall
