I've stalled on it since I made some gross hacks to make the a.out stuff work that was messy. I need to clean it up some more. I promise to clean it up this weekend if my daughter doesn't decide to come into the world this weekend . If you could review and test it that would be great. The worst part is that it needs to be built under linux development. The good part is they support a lot more NIC's then we do. There is atleast one nagging bug that I've been running into lately with memory corruption of variables in the etherboot code. I've fixed a few problems in that area but atleast one persists. Also I've been waiting in the wings to see what will become of FreeBSD's netboot code. It seems to be somewhat orphaned and won't work with elf kernels and the supported NIC list is weak. I guess worst case I could patch it to support elf kernel booting. Doug A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
