GRUB: DOS boot problem

hello,

I hope someone can help me:

I want to boot DOS with GRUB. DOS is located on the 1st HD 3rd
partition, . The point is, that I want to boot DOS from it's
bootsector image dos.bss (512K). I've no problem to boot this image
with the syslinux bootloader. But syslinux is limited to partition
sizes < 1GB and I need to boot a partition of 1.5GB. That's why I have
to use grub.

stage1, stage2, menu.lst and dos.bss are located on /dev/hda3 (i.e.
(hd0,2)):

This is my grub.conf:
---snip---
root (hd0,2)
install (hd0,2)/stage1 d (hd0,2) (hd0,2)/stage2 p (hd0,2)/menu.lst
quit
---snip--

This is my menu.lst:
---snip---
default=0
timeout=0
title DOS
hide (hd0,0)
hide (hd0,1)
unhide (hd0,2)
rootnoverify (hd0,2)
makeactive
chainloader /dos.bss
---snip---

I also tried a grub.conf like this:

root (hd0,2)
install (hd0,2)/stage1 d (hd0) (hd0,2)/stage2 p (hd0,2)/menu.lst
quit

The error message is in both cases 'No system or drive error. Change
and press a key'.

This message comes from the image 'dos.bss'. Thats why assume, that
grub in fact opens the image. But why DOS can not boot and why DOS has
no problem to boot with the syslinux boot loader?

Bye

ok, problem is solved:

I have increased the concerned partition. That's why the dos
bootsector image didn't fit anymore. I made a new image and now it
works fine.
