Sorry, I did a msitake and mixed up my two patches.

This patch should simple build the stage2-diskless
file also, to boot locally the "diskless" version of
GRUB. Espacially for testing this is very useful.

With friendly regards

Hello Mr. Okuji,

I sent the patch only to bug-grub not to you.

Read below mre details.

In simple words: The preset menu is executed first in any way,
and is replaced (concerning menu entries) and overridden 
concerning settings) when a main config file (local or via net)
is present. The network environment will be activated (if using
the diskless version) between the preset and the main menu.

This new implementation does NOT violate your initial idea, but
gives the user the possibility to - for example - activate the
serial interface before running "bootp". Otherwise if the
server is not responding to the target (or other problems
concerning the ethernet link, etc) will lead to an "hanging"
GRUB, as no output is shown on the serial line.

See more details below.

With friendly regards
        Christoph P.

With a little patch in `stage2/Makefile.am' a diskless version of
a stage2 is also built together with nbgrub and pxegrub, to load
the "diskless" version of GRUB locally from disk.

If a machine cannot have a BOOTROM, or if there is a problem
with etherboot/netboot, a boot floppy of the diskless GRUB can be
used. The GRUB boots locally, but does a BOOTP and a download
of the menu from the server (and of course also the OSes, ...)

The GRUB versions now:

local, normal:  [stage1/stage1] [stage2/stage2      = start     +
pre_stage2]
nbgrub                          [stage2/nbgrub      = nbloader  + diskless  ]
pxegrub                         [stage2/pxegrub     = pxeloader + diskless  ]
local, diskless:[stage1/stage1] [stage2/stage2-diskless = start +
diskless  ]

A boot floppy for diskless is GRUB is simply made by

        cat stage1/stage1 stage2/stage2-diskless > /dev/fd0

The `stage2-diskless' is together built with nbgrub and pxegrub, enabled
by
`--enable-diskless' as option in the configure script.

With friendly regardss
        Christoph Plattner
