Enrico Problem solved with your help!! Many thanks for your reply, which put me on the right track. My NE2000 cards are now working. I tried your solution, and they _still_ didn't work, even though all the other NIC cards (ie that were not NE2000's) on my home LTSP network worked just fine. It was only the NE2000's that weren't working for some odd reason. Yours worked and mine didn't. The problem had to be something else. I solved the problem by reconfiguring the wiring of the network very slightly. To explain, I have a mixed CAT5/coaxial network. The LTSP server is upstairs in my house and connects to a 10 Meg hub using CAT5 wiring, and a number of other PC's on the second floor are fed from the hub also using CAT 5 wiring. The hub also has a BNC connector for a coaxial cable network, and the home network connects to a few other computers using coaxial cable which is fed down through the house to the basement - ie - the hub is upstairs at one end of the coaxial cable, and the router is at the other end of the coaxial cable in the basement, again using a BNC connector, with a few machines in between. Because of my house, the setup does actually make sense, it has worked fine for years and works fine with all machines, all running lots of different operating systems (Linux, OS/2, Windows, etc). All of the NE2000 cards were also working fine under all OS'es, _except_ for when I tried to boot them using LTSP. Even more weirdly, other machines on the coaxial cable booted LTSP without problem - it was _just_ the NE2000 equipped ones that didn't work. I solved the problem by checking the coax connections and reconfiguring the coax wiring slightly. I think the impedance on the coaxial network was probably not quite correct. It never showed up using other operating systems, but I think it slowed up the network just enough that the handshaking, etc with the TFTP server got held up somehow, and the system then waited forever. Just my theory. So my NE2000's were working all along (they always got DHCP fine and then got stuck part way through the TFTP part). It was the _network_ that wasn't working (even though it seemed like it was). MORAL OF THE STORY - don't take your network topology/wiring for granted, even if it seems to be working fine.
