Scott,

Thanks for the input...

I couldn't... find any combo of commands that would boot to MsDos
             ...can't determine a method to make 1st primary partition 
active.
            
But it dual boots to FC2 & WinDoze 2000

Here it is...fwiw
#  Grub Configuration File
                                                                                

#  By default, boot the first entry.
#  The first entry (here, counting starts with number zero, not one!)
#  will be the default choice.
default 0              
                                                                                

#  Boot automatically after 10 secs unless interrupted by keystroke
timeout 10
                                                                                

#  If 1st entry doesn't work, fallback to the second entry.
fallback 1

#  Set default colors.
color yellow/blue blue/white
