RE: RE: GPL Win PV driver issues

[Brian Wolfe <brianw@terrabox.com>]

I wish I could help out a bit by compiling for nt2k pro but
unfortunately MS wants me to buy their developers subscription for $1k+
USD. 8-( I can't afford that kind of cash. *sigh*

If anyone can front me the necessary installables for compiling the
windows PV drivers I'm willing to have a go at helping out. :)
