PXELINUX - Modifying
From Wiki
You may have noticed that pxelinux.0 tends to print out quite a bit of debug information. I didn't like this at all for some of these computers, so I modified the pxelinux.0 source and recompiled.
binary download of pxelinux.0.silent
To use this, simply drop it down in place of pxelinux.0, or change the filename paramater in either a host block or a subnet block.
