Raw Normal View History

Allow to boot from DOS if a XMS manager is installed. XMS is recognized and used as temporary buffer for the kernel image. The processor must still be in real mode at program start, so EMM386 or QEMM are not allowed. W*95 is OK. Written by Martin Husemann (pr port-i386/3336). Completely separated from other bootloaders for sanity.

# $NetBSD: Makefile.booters,v 1.4 1997/06/13 17:49:22 drochner Exp $
Initial import of new boot code, created by Matthias Drochner with a little hacking by me. This isn't strictly identical to his 920312 release -- I've hacked it a bit -- but since we are taking over change control it doesn't matter much.

Force inclusion of "diskbuf" into bootsectors. This allows to build bootsectors containing netboot code ("make netboot.sym" in the netboot directory).
