From mboxrd@z Thu Jan 1 00:00:00 1970 From: fair-tuhs@netbsd.org (Erik E. Fair) Date: Mon, 23 Nov 2015 00:40:40 -0800 Subject: [TUHS] Porting 2.11 BSD In-Reply-To: <20151123090509.Horde.anntqPoOVbgXR9r5HlrgBxs@avocado.salatschuessel.net> References: Message-ID: <26595.1448268040@cesium.clock.org> With regard to cooperating with extant system firmware, this is a problem that NetBSD has on almost every platform it runs on (and it runs on many). You can find many examples of how to cooperate or work-around firmware bootloaders in our BSD-licensed codebase: http://www.netbsd.org/ Further, we've got a standard secondary booter framework, though we retired a.out quite a few releases ago. See src/sys/arch/*/stand (for "stand-alone") in our source repository. Or grab the source tarballs as you see fit. Some of this is deja vu for me: I was a co-founder of the "Undergraduate Computing Facility" (UCF) at UCB in 1982, and helped set up the Z8002 based Onyx system in B50 Evans Hall that was our first and for a long time, only, computer. The undergrads who used that system to learn Unix ported many a BSD utility to that system (at least the ones that weren't too RAM-hungry), starting with BerkNet so we could move files around easily & have E-mail. good luck, Erik
