So what if grub can't & lilo can, grub CAN boot lilo...

It would appear that on Jun 1, Joe(theWordy)Philbrook did say to Phil Schaffner:

...
 this grub.conf entry

 title DrDos
         map (hd0) (hd1)
         map (hd1) (hd0)
         rootnoverify (hd1,0)
         makeactive
         chainloader +1

 doesn't work... Yet this lilo.conf entry

 other=/dev/hdc1
         label="DrDos"
         table=/dev/hdc
         map-drive=0x80
            to=0x81
         map-drive=0x81
            to=0x80

 does work???

 # this device map was generated by anaconda
 (fd0)     /dev/fd0
 (hd0)     /dev/hda
 (hd1)     /dev/hdc

 To be fair, grub does try to boot DrDos... Which gets far enough to say
 it's starting before it locks up...

 When I use the lilo boot, DrDos loads completely and runs under the
 belief that /dev/hdc1 is C:

 Hmmnnn I wonder, since lilo CAN boot DrDos, I wonder if I installed a
 normally useless copy of lilo to hdc (lilo -b /dev/hdc) Would I be able
 to add that lilo to the menu of the grub setup in (hd0)???

 If so, is there a good how-to you could point me at?
   Never mind the how-to.... I decided to "wing it" and got lucky!

I figured that if the interactive grub command
setup (hd0) 
sets grub up to the mbr of (hd0) then pointing a chainloader at (hd1)
should start with the mbr of (hd1)... I was right!

"So what if grub can't & lilo can, grub CAN boot lilo..."

I set up a lilo.conf with the above DrDos entry, did a

lilo -b /dev/hdc

And stuck this

title to_DrDos_via_lilo
        rootnoverify (hd1)
        chainloader +1

in my grub.conf which allows grub to boot lilo which CAN load my DrDos.

Now I can have my cake (use grub) And eat it to (keep lilo)

Thanks for all the help to all the good people on this list who offered
clues and more.
