2000-02-07 OKUJI Yoshinori <okuji@gnu.org>
The netboot support is heavily rewritten, based on
Etherboot-4.4.2. The current one doesn't work yet, so check out
GRUB with the tag "dresden_netboot_code" if you need working
one.
* configure.in (--enable-tftp): Deleted.
(FSYS_CFLAGS): `AC_SUBST'ed right before AC_OUTPUT.
(NETBOOT_DRIVERS): New variable. AC_SUBST this after examining
the driver options.

* stage2/asm.S: Undo the previous changes. Is
