Thanks.  I will ask Mark if he can do that.  For now, if you have a grub
with a hello world, I would love to have it since I can't boot my old
PC with the old grub I have.  Jeffrey Engel was nice enough to send me
a real Novell NE2000 ISA card and I want to get it up under RTEMS.  I
it working now under Windows so I know the net connection is OK.  I just
can't boot RTEMS on this PC yet.  

Again thanks.  It will be nice to have up to date instructions and
boot floppy support.
