Re: Help with GRUB and Network Boot

first of all, is it possible to use `$VARIABLE's ?
Or is this only the notation you use here ?

It is not necessary to build a new image includining initrd.
Simple use NFS-ROOT.
If you use a DHCP/BOOTP server, you must compile in the auto IP
config into the kernel and use `ip=bootp' as kernel parameter
or you do the configuration statically using `ip=......',
`nfsroot=.....'. For more details see the diskless HOWTOs and
the NFSROOT HOWTOs. The `ip=' has many options .....

I hope I could help you ...
