I'll try to send yu a working pxeboot, after I test it under vbox (haven't tried for some time), in the mean time make sure that your /etc/exports is realy ok should be at least: -maproot=root and does not harm: -alldirs also, check if you are nating, or bridging, can't remember what I used. and one last thing, vbox/ethernet does not behave nicely after reboot and also make sure you choose PCnet-FAST II, the III does not work hth, danny
