Syslinux - Oct 2007 - DOS/Freedos: Can't use mkfloppyimg.sh or mkdiskimage for +8M images

Hi

Maybe HPA or Murali could help me with this one, or anyone who got the
following working. I spend numerous hours reading the list and
googling without success.

I'd like to create a bootable USB stick and  CDROM that will do the
following.

I will have a menu, from which I could pick a specific dos image (not
partition). The dos images could have up to 20Megs in size.  The goal
is to have a  configuration that will contains tools for different
type of hardware. To ease the process, I want to automate image
creation (floppy or harddisk), and use it with memdisk.

I use the mkfloppyimg.sh script and it is working fine up until 8M in
size, if I go higher than this, it doesn't work, and I can't boot the
image. I did try to do the same with mkdiskimage without success, I
probably miss something in the way to create the image. My question is
simple, is there any recipe to create a +8M dos/freedos image I could
use with syslinux.

Many thanks.

It would probably help if you explained what you actually did.

Which of the following happens
(1) mkfloppyimg.sh is failing and not creating the image
(2) memdisk is not booting the created image
(3) memdisk is booting the image, but DOS complains while booting.

Also what is the exact error message you are seeing?

I am assuming you gave the "floppy" and "c/h/s" values to
memdisk, since
otherwise you would not have been able to boot a 8MB image.
