This should be normal (I think) if there was no operating system on that 
drive.

Please post your "menu.lst" file. In general, here is how to add an entry 
for any non-Multiboot-compliant (which is just about all :) operating 
systems:

--cut--

# Generic booter
title=Generic
root=(hd0,0)
makeactive
chainloader=+1

--cut--

Replace (hd0,0) with your hard drive and partition. For example, the 
first partition on DOS drive D: would be (hd1,0). What the above does is 
tell GRUB to load and execute as the BIOS would the first sector (the 
boot sector) of the specified hard disk and partition. I haven't been 
able to test this with OpenDOS (still can't get a working HD install, and 
the FD install is of no use since my first floppy disk is a 1.2) but it 
should probably work.

Sure it should work. As to not mentioning OpenDOS, that's to be expected 
since OpenDOS wasn't released yet, and the author of GRUB probably still 
has never heard of it. :)
