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 ?
