Thanks.
I still think chain.c32 should be able to do a reverse partition lookup,
to determine from which partition it was booted.
This would be useful to boot ntldr, setupldr.bin, bootmgr, grldr, ... when
you want to boot it from the same partition as from which SYSLINUX is
booted, without specifying the partition explicitly to chain.c32.
Eventually only when a parameter is added like "bootpartition":
LABEL grub4dos
COM32 chain.c32
APPEND bootpartition file=/grldr
