It should be noted that all filename references are relative to the
directory pxelinux.0 lives in (usually /tftpboot). PXELINUX
-generally requires that filenames (including any relative path) are 63

characters or shorter in length.
PXELINUX does not support MTFTP, and I have no immediate plans of
specified in the global section of the file (before the first
LABEL command.) The default for "image" is the same as
"label", and if no APPEND is given the default is to use the

Note that LILO uses the syntax:
