I reckon these are the cards of choice myself and apparently people are picking them up for ridiculous prices in the US. You want to look for PCnet or Lance based cards to use the lnc driver. The is driver is going to be dropped probably after the next release since it's now superceded by the lnc driver. Someone in the NetBSD lists said they picked up a 32 bit PCI PCnet card for $79! Apparently it needs PCI config support to be written into the driver before it will work since the driver doesn't know the irq pin etc. If someone wants to send me one I'll happily get it to work. I've got the docs next to me here :-) -- Paul Richards, FreeBSD core team member. Phone: +44 1222 874000 x5958 (work), +44 1222 457651 (home) Dept.
