grub choices

[Mark Grieveson <dg135@torfree.net>]

Hello.  I installed ms-dos, and then shrank it, and subsequently 
installed Debian in its own partition.  Debian's grub, however, did not 
see ms-dos as an operating system, and, therefore, did not set up a menu 
choice for it.  How do I go about setting up a menu choice for it in grub?

Thanks,

Mark
