7. populate /pxeroot tree using script in
/usr/share/examples/diskless/clone_root
(change DEST to /pxeroot)
8. edit /pxeroot/etc/rc appropriatelly if necessary.
I make one file from rc.diskless1 and 2 (this is just ugly hack, but
working properly:):
chkerr() {
case $1 in
0)
;;
*)
echo "$2 failed: dropping into /bin/sh"
/bin/sh
# RESUME
;;
esac
}
# Figure out our interface and IP.

9. edit /pxeroot/boot/loader.rc:
echo Loading kernel...
load /kernel
echo Booting...
set vfs.root.mountfrom="nfs:"
boot
10. Enable PXE on your card and boot.
11. I had some problem with out NBASE switch, which doesn't like DHCP or
so. Switching connection to Baystack enabled booting... I don't know why.
Maybe I forgot some step, so I you will have some problems, write me.
