[openbeosnetteam] Re: Drivers...

Speaking of drivers....  Is there source code available for the standard
tulip driver?  I'm tired of taking my one nic down to test, so I want to see
if I can get 2 nic cards working.  Unfortunately, my 2nd nic is a Linksys
v4, which isn't supported by the standard linksys driver, however it is a
tulip, so I'm thinking I can tweak it.
