You have to uncomment that hints line, remove the # in front of the
line. Normally the loader will load the hints file for you, but
etherboot doesn't do that for you.

If you use pxe to netboot, pxeloader will load the hints file for you
but etherboot isn't clever enough to do it, so you have to compile it
into your kernel.
