Try this:

Move the grub.cfg file back to where it was before, then comment out
the first three lines of the file (the lines starting with 'terminal'
and 'serial').  Try booting grub again and tell me if you get any
output.

If this works, you will also need to change the kernel command lines
in /tftpboot/frisbee_linux/grub.cfg and
/tftpboot/admin_linux/grub.cfg.  Delete the part that says
'console=ttyS0,115200' to force the output to go to the VGA console.

Thanks.
