Re: Diskless booting -- how?

[Christoph Plattner]

To correct you ....

... you do not put the GRUB into the NIC BOOT ROM, but a NIC boot
loader, for example the "etherboot" project (from where GRUB's
NIC drivers are derived from !), or "netboot" project (I prefer
etherboot by now).

It is "only" a mini extension to the PC BIOS to load via BOOTP or
DHCP a config and load via TFTP a specified boot file. Etherboots
supports some formats. For example the LINUX kernel must be 
prepared with a special tool to load. This perparation is already
done for GRUB: "nbgrub".

This "nbgrub" is a file in the NBI format which is recognized by
etherboot or netboot. And after loading GRUB, GRUB can do everything
as normal ! So you need no LINUX kernel perperation, etc...

Enjoy.
