GRUB and Networking
Limited range of network cards supported.
Can be booted diskless over network
(if the machine has Net Boot ROM or
Etherboot ROM code)
Can get IP address, parameters
Can use bootp or dhcp
Can see a network drive (nd) using tftp
Can boot other operating systems from (nd)
Notes:
GRUB has support for a limited range
of networking: just over 21, whose
drivers come from the etherboot
software. Networking does not work if
you compile in drivers for two or more
networking cards. You must use bootp
or dhcp to get your IP address, but you
can select your own tftp server. The
files on your tftp server are visible as
if they were on a network disk, and you
can boot several operating systems
from this.
