Not to toot my own horn but if your just trying to duplicate most of the
resources on UBCD you might want to look at http://pxeknife.erebor.org
as it will work fine with all of the syslinux family.  UBCD however will
not as it makes a LOT of assumptions about how it works, where it can
get things and which utilities and what not it uses to load it's images
(it's not limited to syslinux).  So the problems you might be seeing in
getting UBCD to work may not be related to your image or syslinux, it
may be related to the fact UBCD can't really be converted.
