[I've seen your previous answer, but I still will describe my setup] [problems netbooting machines between fxp and em NICs] Hello, I am too seeing problems jumpstarting a machine (client) using a fxp NIC from a server (runnning 5.1-Rel) using an em NIC : the em NIC is wired down as 100baseTX full-duplex, but the 5.1-Release kernel seems unable to see it and tries to use a half-duplex setting (this surprisingly works when loading the install bits via ftp, with a rate of around 44kB/s, but fails completely when NFS is selected as install media). Everything works finer after switching virtual consoles on the client and "ifconfig'ing" the fxp1 as full-duplex, from the holographic shell. What is even more startling is that the same fxp1 is correctly set up as full duplex with the 4.8-RELEASE install kernel (from the same boot server, with the same setup for its NIC : I've installed two tftpboot directories so as to select which release is loaded via PXE). On monday , I'll try to wire the server em NIC as half-duplex to see wether the client fxp1 has a better throughput (afterwards, I'll try and look for differences in the 4.8 and 5.1 fxp drivers). Happy hacking TfH
