These imply that the Amiga sees the X-surf card, but not its on-board ISA card. If you examine the X-surf, you’ll notice that its really two cards combined. The Network Interface Card (NIC) is a standard model available for PCs, while the rest includes a pseudo ISA slot, which is connected to the NIC. The connection is covered with two strips of plastic, one on either side. It may be that this connection is faulty. A bit of solder may do the trick, but be careful. Alternately, the NIC itself may have troubles. This bit--

[emphasis added] –suggests that the Amiga is writing to the NIC’s memory, but that not all of the data that is read back matches what was written. Since most of the data is read back correctly, the connection between the cards is probably okay. New cards of that sort should be cheap enough, and if the memory is in a socket, it should be easy to replace.
