[ale] Using PXE to boot Live Ubuntu CD

[William Fragakis]

In a linux world, using dhcpd, those options are what tell the pxe
booting box where to look so it can boot. My knowledge beyond this is
thin but I do know that not having those two entries correct is a sure
way to spend lots of frustrating hours.

In the past, dhcpd would, by default, declare itself as 'next-server'
but now it must be specified.

This may be helpful (inspired by Jim's post) or at least point you in
the right direction

https://help.ubuntu.com/community/UbuntuLTSP/LTSPWindowsDHCP

If you aren't familiar with LTSP, it delivers, typically through PXE
boot, a small kernel to the booting box so it act as a thin client.

regards,
William
