1Important notice for ATAPI support on FreeBSD: 2 3A long time it was not possible to decently write CD's using ATAPI drives 4on FreeBSD because ATAPI was not supported in an orthogonal way on FreeBSD. 5 6These days (in the mid of november 2001) first ATAPI support for FreeBSD is 7available as patch. Please read: 8 9http://www.freebsd.org/cgi/getmsg.cgi?fetch=136602+0+/usr/local/www/db/text/2001/freebsd-current/20011111.freebsd-current 10 11and get the FreeBSD kernel patch from: 12 13http://www.cuivre.fr.eu.org/~thomas/atapicam/ 14 15Thanks to Thomas Quinot <thomas@cuivre.fr.eu.org> for the patch. 16 17We tested the patch with a collegue today (23.11.2001), here is the result: 18 19- From our tests, it compiles with FreeBSD 4.x and FreeBSD current (5.0) 20 but does not boot with FreeBSD current so we used 4.x for our tests 21 I hope that Thomas Quinot <thomas@cuivre.fr.eu.org> and 22 Kenneth D. Merry <ken@kdm.org> will help to make it work with 23 FreeBSD current soon. 24 25- The Author of the patch, Thomas Quinot <thomas@cuivre.fr.eu.org>, observed 26 that it runs on *some* -CURRENT machines and hangs on *some* -STABLE 27 machines so you may want to test what works best for you. 28 29- It does not run the SCSI commands in silent mode so the ATAPI low level 30 code prints unwanted kernel messages when you start cdrecord. 31 32- cdrecord runs without problems so far it has been tested! 33 34You need to apply the patch, change your kernel configuration to include 35 36options ATAPICAM 37 38and then recompile install and boot the new kernel. 39Make enough /dev/pass* devices and start testing..... 40 41/*--------------------------------------------------------------------------*/ 42From shamrock@cypherpunks.to Mon May 3 07:35:50 1999 43Received: from pakastelohi.cypherpunks.to (pakastelohi.cypherpunks.to [212.26.192.194]) 44 by mailhub.fokus.gmd.de (8.8.8/8.8.8) with ESMTP id HAA18680 45 for <schilling@fokus.gmd.de>; Mon, 3 May 1999 07:35:48 +0200 (MET DST) 46Received: from localhost (shamrock@localhost) 47 by pakastelohi.cypherpunks.to (8.9.1a/8.9.1) with SMTP id HAA26150 48 for <schilling@fokus.gmd.de>; Mon, 3 May 1999 07:35:44 +0200 (CEST) 49Date: Mon, 3 May 1999 07:35:44 +0200 (CEST) 50From: Lucky Green <shamrock@cypherpunks.to> 51To: schilling@fokus.gmd.de 52Subject: Re: Cdrecord "RR-scheduler not available" (fwd) 53Message-ID: <Pine.BSF.3.96.990503073330.26028A-100000@pakastelohi.cypherpunks.to> 54MIME-Version: 1.0 55Content-Type: TEXT/PLAIN; charset=US-ASCII 56Status: R 57Content-Length: 1423 58 59Schily, 60Please add the following info to your readme for FreeBSD.
