Booting a DOS floppy image using GRUB |

As I understand it, netbooting of DOS can be done using a floppy
image which is specially altered to make the BIOS floppy calls
read from a ramdisk instead of from the physical floppy. This
would be of considerable help to us, especially on a large number
of machines where GRUB (0.95) is already installed. The network
aspect of this is not really necessary, though I can in fact
get the parameters using GRUB's bootp command, and, for example,
boot from a linux image and ramdisk using the kernel and
initrd commands with (nd).
What I would like is to transfer a netboot image, which I have
created, for example, using etherboot (version 4.7.6), into memory
and booting it as a virtual floppy. I have not succeeded in doing
this using either the kernel or the chainloader commands in GRUB,
since the floppy image is not that of a supported kernel, while
the chainloading simply fails.
Am I mistaken, or should it be a fairly simple matter to add
a new 'kernel type' which is a DOS floppy image? Will this
work?
I'm not sure where else to ask.
By the way, I'm giving a presentation and demo of GRUB at the
Leeds Linux user group next Monday (http://www.scs.leeds.ac.uk/wylug/).
I'm very grateful to you for all the work you've been doing on
GRUB in recent years.
