Which version of M-SYS DFORMAT?

Which version of M-SYS DFORMAT?

[Stephen Lee]

I'm following the instructions at
http://lakeshoremicro.com/diskonchip-grub-howto.html
on installing Grub on to a DOC2000 chip. With M-Sys' v5.14 DFORMAT, I
get the "Sorry, we don't support UnitSizeFactor of != 1 yet." message
during bootup. The kernel (2.4.20) was patched with
mtd-snapshot-20030423.tar.bz2. According to the instructions, patching
with the latest mtd patches should take care of the problem. This leads
me to wonder if I should have used the V4.2 DFORMAT instead?

Thanks,
Stephen

Replying to my own message. The answer is that "dformat /win:d800
/BDKF0:grub_firware" only works with v5.14. The next question is did I
screwup the mtd patch? It doesn't appear to be as all kinds of
MTD-related kernel config settings appeared after patching. I should
also mention that Grub was installed correctly onto the DOC2000 as it
booted up to the Grub prompt as expected. The only thing I can't do is
mount /dev/nftla1 to install the kernel and menu.lst. Suggestions?

Thanks,
Stephen

Stephen,

I apologize if the instructions aren't clear - if you use version 5.x of 
DFORMAT, you'll have to use your patched kernel twice.  In order to mount 
/dev/nftla1 and copy the bzImage to the DiskOnChip, you would need to boot 
from a hard drive using the patched kernel, or insmod the appropriately 
patched modules.

Once you are able to copy the kernel to /dev/nftla1, the patched kernel will 
also be necessary to boot directly from the DiskOnChip.

Thanks Mark. That did it. Now I've managed to fdisk and install the
kernel and menu.list onto the DOC but upon reboot, Grub command line
appears but Grub cannot find the root device (refering to the Grub
root). Entering "root (<tab>" only gives fd0 or hd0 as the choices.
"dc0" is not available. Did I do something wrong during building of
Grub-mtd? The main difficulty in build mtd-compliant Grub was making
sure the autoconf and automake versions were correct. In the end I did
get grub_firmware in the stage1 directory but how to be sure the build
was correct?

Thanks again,
Stephen

Autoconf was indeed the problem. Upgrading it resulted in a functional
grub_firmware file. It turns out that I also needed to upgrade Perl :-(
