Syslinux - Oct 2009 - [patch] PXE-On-A-Disk: etherboot2ethersel.pl patched for etherboot-5.4.3+dfgs

PXE-On-A-Disk from
(ftp://ftp.scyld.com/private/jlehan/pxe-on-a-disk.html) was posted on
syslinux mailing list:
http://syslinux.zytor.com/archives/2005-December/006222.html.  It is 
being mentioned by syslinux wiki, or some other documentation of 
syslinux that I currently can't find.

  I tried etherboot2ethersel.pl from PXE-On-A-Disk
(ftp://ftp.scyld.com/private/jlehan/pxe-on-a-disk.html) with
etherboot-5.4.3.  I hope it doesn't matter much that I actually used
Debian source package.  It failed:


    $ ./etherboot2ethersel.pl.orig etherboot-5.4.3+dfsg/src/bin/ TEMPDIR/
    Sorry, couldn't find
etherboot-5.4.3+dfsg/src/bin//mlx_ipoib/mt23108.zlilo file, may be a
    problem with make allzlilos at ./etherboot2ethersel.pl.orig line 
189, <ETHER> line 365.


  I patched etherboot2ethersel.pl to fix it:


    $ ./etherboot2ethersel.pl.patched etherboot-5.4.3+dfsg/src/bin/ 
TEMPDIR/
    Now reading from NIC file and generating SYSLINUX.CFG file
    Done!
    Supported 32 drivers and 273 cards
    (Skipped 8 bad drivers and 13 bad cards)
    (Skipped 52 unrecognizable lines in file)


The patch also adds a -d command line switch.  This switch replaces the
need to edit the script in order to produce debugging information by a
command line switch.

What about gPXE as opposed to Etherboot?
