The current chain.c32 file from Mageia is already patched. To be able 
to replicate the issue, at least you would need chain.c32 v.6.03 prior 
to the patch (e.g. the original v.6.03). Then the isolinux.cfg entry 
should be:

label harddrive
com32 chain.c32 hd0 

or:

label harddrive
com32 chain.c32
append hd0 

(no "exit") as it used to be before the patch.
