I?d be happy to run tests and otherwise gather data. I have seen this before as well, I tried to debug it, then some changes someplace suddently made it disappear and I was unable to duplicate it. Note I also use a very sacred pxeboot image from a 11.x system I saved that just works for me. I boot systems with a native pxe rom, they are handed my custom built more complete pxe that understands nfs and http. I then boot our loader and kernel via nfs. The only thing I do over tftp is to hand out my customer version of the pxe code and my menu.pxe file. > Jon > -- > jonathan@FreeBSD.org -- Rod Grimes rgrimes@freebsd.org
