There is some disagreement what the proper thing to do with the 
signature is.  One school of thought is that it should follow the boot 
sector code, another is that it should follow the superblock, i.e. the 
system that partitioned the disk.  The Microsoft recommends leaving this 
field as "MSWIN4.1" at all times, which seems to somewhat follow the 
latter theory.

Accordingly, I changed Syslinux quite a while ago to the "latter theory" 
of operation - it does *not* overwrite the system signature.
