[CLUE-Tech] GRUB: Dual-Booting Linux and DOS, Part Deux

[Warren]

Achtung GRUB gurus,

I'm setting up a Linux/DOS (Yes, DR-DOS) dual-boot box with 2 IDE
drives; drive 1 (hda) is a 2GB drive with Linux set to "master" and
drive 2 (hdb) is a 1.6GB drive with DOS and FAT set to "slave".  Both
are on the same cable.

My grub.conf looks like:

  title Red Hat Linux (2.4.7-10)
          root (hd0,0)
          kernel /vmlinuz-2.4.7-10 ro root=/dev/hda2
          initrd /initrd-2.4.7-10.img

  title DOS
          root(hd1,0)
          chainloader +1

          
RH boots fine, but selecting DOS give me the error:

  Error 13: Invalid or unsupported executable format

  
What dumbass error am I making?
