Supposed to have 2 dual-link DVI, and TV-out. They recently released the preliminary schematic, and are looking for people to review it. Hardware bugs, changes that would help the device drivers, etc. If you have ever complained about a hardware design, here is your chance to influence a design *before* the mistake is committed to silicon. schematic and BOM at: http://natsuki.kinali.ch/ http://opengraphics.org/ Beware, some of the info here is out of date. mailing list archive: http://lists.duskglow.com/open-graphics Step one is FPGA to work the bugs out. (and perhaps useful for other things) Step two will be ASIC ( smaller, cheaper, less heat, and faster then the FPGA ) From owner-freebsd-drivers@FreeBSD.ORG Mon Mar 20 11:32:28 2006 Return-Path: X-Original-To: drivers@freebsd.org Delivered-To: freebsd-drivers@FreeBSD.ORG Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 7715A16A423 for ; Mon, 20 Mar 2006 11:32:28 +0000 (UTC) (envelope-from knoll@edv-design.at) Received: from smtpout.internic.at (smtpout.internic.at [212.126.64.21]) by mx1.FreeBSD.org (Postfix) with SMTP id 826DE43D58 for ; Mon, 20 Mar 2006 11:32:25 +0000 (GMT) (envelope-from knoll@edv-design.at) Received: from unknown ([80.108.175.25]) by smtpout.internic.at ; Mon Mar 20 12:32:09 2006 x-fsavag4mse-ts: a234ea8fdd13cc04 Content-Class: urn:content-classes:message Keywords: disclaimer Content-Transfer-Encoding: 8bit MIME-Version: 1.0 Content-Type: multipart/related; type="multipart/alternative"; boundary="----_=_NextPart_001_01C64C11.E455DC28" Date: Mon, 20 Mar 2006 12:31:48 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.3790.1830 Message-ID: X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: Drivers and Failover on IBM Storage DS4800 and DS8000 thread-index: AcZMEd/w0S1dQfwyS8OyvMpOYt1jYg== From: "Ing.
