A non-maskable interrupt (NMI) is an interrupt type which differs from standard interrupt mechanism by enforcing attention from the interrupt processor (usually the CPU).  This solution discusses an NMI is in more depth and how they are handled.

### What is an Interrupt ? ###

Modern systems architecture has created tightly coupled connect between system components.  Work for components can be handed off to a component for completion.  Rather than wait for the component the main CPU can be tasked to do other pending work.

When the component has completed its work it will raise a signal to the main processor.  The main processor considers this signal an "interrupt", as the current work on the CPU will be interrupted immediately   Each component has a number assigned to it.

### Why "mask" an interrupt ? ###

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

Go into your git checkout folder of ipxe.

Save the below file as nic-menu.ipxe.

Build iPXE like this:

cd src && make EMBED=../nic-menu.ipxe && cd ..

Requirements: current iPXE as of 2013-08-01 (for proper behavior of autoboot with a network device specified, netX feature, PCI vendor/device ID display and inc command)
