grub cannt boot from doc millennium

[cytang]

I searched the mail archive with keyword "grub"
but I only find just one detailed howto : 
http://lists.infradead.org/pipermail/linux-mtd/2001-October/003475.html
Accroding to it ,step by step  on my DoC millennium
(8M), but  I still end up with failure.
My all steps as follow, did I miss something?
1.make a new kernel with DOC support with 2.4.2-2
kernel source  on my RH7.1 box
2.tar zxvf grub-0.90.tar.gz
3.cd grub-0.90; 
  patch -p0 < /usr/src/mtd/grub/grub-0.90-doc.patch
4. rm configure;
   autoconf
5. make ; make install;
6. cp stage2/pre_stage2 /usr/src/mtd/grub
7. cd /usr/src/mtd/grub; make ; cp grub_firmware
/usr/src/mtd/util/
8. cd /usr/src/mtd/util; make ;
9. ./eraseall /dev/mtd0 
10 ./nftl_format /dev/mtd0 98304   
11  fdisk /dev/nftla
     n
     p
     1<Enter><Enter>
     w
     mke2fs /dev/nftla1
     ./doc_loadbios /dev/mtd0 grub_firmware
 
12. # this part install grub on hard disk
   
    mkdir /boot/grub; 
    cp ~/grub-0.90/stage1/stage1  /boot/grub/;
    cp ~/grub-0.90/stage2/stage2  /boot/grub/;
    vi /boot/grub/menu.lst
    timeout 30
    default 0
    fallback 1
    #For booting linux kernel with doc support from
harddisk
    tile linux
    root (hd0,0)
    kernel /boot/bzImage-doc  root=/dev/hda5
    #For booting linux kernel from doc
    tile linuxondoc
    root (dc0,0)
    kernel /boot/bzImage-doc  root=/dev/nftla1
13 grub
   root (hd0,0)
   setup (hd0)
14 reboot

enter grub console : (I dont know why not enter menu
select )
root (dc0,0)
error 21: selected disk does not exist

only 
     root (hd0,0)
     kernel /boot/bzImage-doc root=/dev/hda5 
can boot

There is a short how-to in the README_DiskOnChip file created by the
patch.

Run 

    ./configure --enable-diskonchip-mil512

or

    ./configure --enable-diskonchip-mil256

depending on the type of the DoC Millennium flash parts.  You may want to
explicitly disable unused file system drivers and leave only required one.

This and the next step are no longer needed.  The README_DiskOnChip file
suggests to obtain the GRUB bootloader firmware from stage2/grub_firmware.
