Halas, I still have those problems with a 3c590. Tried ALL the drivers I Could find :
0.25 0.28C 0.28C-all 0.35 (the special boomerang one)
And each time, after a week or so, the 3c590 stops working. As this machine is a NFS, NIS, Web & Proxy/Cache server, you can imagine the mess...
I put a Ne2000 :-( in it for the moment....
I have a bunch of machines with 3c590, and there is only two which are gaving me problems. (all are 8k 3c590 cards). Those two machines are the more loaded machines.
I haven't any ideas about what cause this problem. I'm wondering if the 3c590 parameters/optimizations (set by the 3c59xcfg.exe DOS program) can cause troubles ?
