Configuring your DHCP server for iPXE booting
NOTE: This is Part 5 in a series on booting Ubuntu from an iSCSI disk. View all of the sections here. Previously we setup a iSCSI target (server) and installed Ubuntu to the iSCSI disk.

Preamble… I recently purchased a 2011 Macbook Pro. Not long after, I installed Ubuntu 11.04 Natty which came with a shiny new Unity desktop.
