Re: pxegrub from floppy?

Hello !

You have to ways to get your goal !

1)
You use a standard GRUB from floppy and use a config file
(`/boot/grub/menu.lst'), which has the line
        bootp --with-configfile
instead of defining menu entries. Then GRUB will open the
menu file from the TFTP server

2) 
You can build a "hack" stage2 using

        cat stage2/start stage2/diskless > stage2/stage2-diskless

Then you can do the primitive boot floppy

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

This should work.

Version (1) is the more user-near and better solution.
Solution (2) is the hacker version !

So words to (1):

You can ofcourse combine local menu and network menu
(you can switch between them). For example one menu
entry of the local menu includes

title NET MENU
bootp --with-configfile

... and the menu on the server includes the line

title LOCAL MENU
configfile (hd0,0)/boot/grub/menu.lst

BTW: Do not forget the `(nd)/' inside the DHCP/BOOTP
definitions for the menu not to have a mixup with the
default devices (local or net).
