you can also boot netbooter off a hard drive partition and net-install
that way as netbootcd runs in ram
add this entry to your menu.lst/grub.cfg
Code:
title NetbootCD-3.1.2
root (hdx,x)
kernel /boot/kexec.bzI quiet norestore base nolocal
initrd /boot/nbinit3.gz
Code:
menuentry "NetbootCD-3.1.2" {
linux /boot/kexec.bzI quiet norestore base nolocal
initrd /boot/nbinit3.gz
}
