booting iso image having syslinux

[J.Bakshi]

Hello list,

GRUB2 has a cool feature to boot .iso image.  It is really a cool
option as we can simply put the .iso and test it without making a cd.
Some of the .iso has syslinux inbuilt. Like live .iso of gparted and
dban. How can we manage those .iso ? We need to call the syslinux.cfg
in those distros to get the boot option ( ex- dban ). Could any one
kindly focus on this issue ?

Thanks
