Reply-to: phk@freebsd.org Date: Sat, 30 Nov 1996 23:33:50 +0100 Message-ID: <6423.849393230@critter.tfs.com> From: Poul-Henning Kamp Sender: owner-hardware@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Most P6 motherboards seems to have the "debug" connector for each CPU. As far as I know you can get hold of the boundary-scan signals of the CPU this way, and poke around and debug the state of it. Now, are there anybody out there who knows what it would take to get something that plugs into that connector ? Preferably something that could be controlled from FreeBSD... -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@ref.tfs.com TRW Financial Systems, Inc.
