Something else that doesn't work with the X-surf-100? I bought one of those IDE4Zorro2 cards for my A2000, and, the x-surf-100 will not work with this card either. As soon as the TCP/IP stack is initialized, it locks the computer up so that the mouse will not respond and the floppy click stops. I didn't have that problem when I was using a plipbox instead of the x-surf-100.
