DRAC/ILO/Similar out-of-band management options are not software as
such, they are firmware which runs alongside, providing the user with
a network address and capabilities for remote access. Whey you are at
grub selection menu, there's no networking available yet. Look for
outside-grub solutions. As mentioned, you can always boot into a small
OS and initiate the next one. If all you have is a cheap off-the-shelf
desktop PC with no out of band management capability, try using a
networked KVM, there are stand-alone versions where you plug USB and
mouse and plug it into the switch and do a remote desktop / vnc into
it. If you have plenty of these desktop-servers, invest in a rackmount
networked KVM, they work pretty well.
