The only syslinux code in my example is mbr.bin that is a generic MBR 
binary code to boot from the
first partition which has the bootable flag. In those steps we can avoid 
writing syslinux's mbr.bin into
/dev/loop0 and using install-mbr binary, which isn't related to syslinux 
and provides the same
functionality, coded in a different way.

isolinux hybrid -partok- images (like SLAX, Debian, ...) works if MBR 
code is the one provided by syslinux (mbr.bin)
but also if the MBR code on the disk is installed by 'install-mbr'.
