Chainbooting iPXE from PXELinux

You can set up iPXE to use a built-in driver for network communication (ipxe.lkrn) or Universal Network Device Interface (UNDI) (undionly-ipxe.0). You can choose to load either file depending on the networking hardware capabilities and iPXE driver availability.

UNDI is a minimalistic UDP/IP stack that implements TFTP client. However, UNDI cannot support other protocols like HTTP. To use HTTP with iPXE, use the iPXE build with built-in drivers (ipxe.lkrn).
