Re: second NIC problem
Hello Nick,
You are right. It is only the problem of irq setting for the NICs. I
re-arrange the irq for the two NICs as followings:
1. isa port 300/16 irq 10 for 3c509
2. isa port 240/32 irq 5 for ne2000
The all things work ok and the eg0 problem gone. I am going to use the
system as bridge or router as our LAN. Thanks for your hints.
