If so, it may be that the old blocks except a certain fixed entry point for the kernel and the breakage could be my fault. At one point during the PXE stuff the entry point of the loader was bumped up to 2 meg (from 1 meg) and it stayed that way, though it should be fine to knock it back down to 1 meg again. If you can produce the problem try reverting that makefile tweak to teh loader makefile to see if it works again. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.Baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
