Putting the ip number in the root-path cures the pxeboot failure. But is still only configure the NFS ROOT according to the kernel's output. I had a look at the pxe code in /sys/boot/i386/libi386/pxe.c where pxeboot is built from and in /sys/i386/i386/autoconf.c which is the kernel side and it looks like they don't do anything about swap. There is a /* XXX set up swap? */ placeholder though. :-) John -- John Hay -- John.Hay@icomtek.csir.co.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
