However, it would go into swap hell if I tried to make kernels locally. It was only usable because I did most things were done on a cpu server. With 16mb, you can still run bigger screens than 640x480x8. at 16MB on a terminal the kernel gives 60% of the memory to the kernel. You can make it more still if you want by including in plan9.ini *kernelpercent=90 for example, to get 90%. Of course, that leaves precious little for processes. --upas-kwelspvbqvnazfwqvgicyftsho Content-Type: message/rfc822 Content-Disposition: inline Received: from plan9.cs.bell-labs.com ([135.104.9.2]) by plan9; Mon Nov 20 15:50:21 EST 2000 Received: from mail.cse.psu.edu ([130.203.4.6]) by plan9; Mon Nov 20 15:50:21 EST 2000 Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.20.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id 39BC7199F4; Mon, 20 Nov 2000 15:50:10 -0500 (EST) Received: from plan9.cs.bell-labs.com (plan9.bell-labs.com [204.178.31.2]) by mail.cse.psu.edu (CSE Mail Server) with SMTP id B527B199F0 for <9fans@cse.psu.edu>; Mon, 20 Nov 2000 15:49:00 -0500 (EST) Received: from ovid.cs.bell-labs.com ([135.104.50.34]) by plan9; Mon Nov 20 15:48:59 EST 2000 From: "Russ Cox" To: 9fans@cse.psu.edu MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Message-Id: <20001120204900.B527B199F0@mail.cse.psu.edu> Subject: [9fans] memory Sender: 9fans-admin@cse.psu.edu Errors-To: 9fans-admin@cse.psu.edu X-BeenThere: 9fans@cse.psu.edu X-Mailman-Version: 2.0rc1 Precedence: bulk Reply-To: 9fans@cse.psu.edu List-Id: Fans of the O/S Plan 9 from Bell Labs <9fans.cse.psu.edu> List-Archive: Date: Mon, 20 Nov 2000 15:48:57 -0500 The install, because it keeps the file system in RAM, requires 32MB. I've done an install on a 32MB system and I was using pretty much all the memory. As others have pointed out, that's mainly because the image data is all kept in kernel memory, and the compressed file system on the floppy is expanded and kept in memory while being accessed. You could run a simple 640x480x8 terminal with 16MB, but I'm not sure how much can be done with only 8MB. The ATI video cards come with a wide range of memory depending mainly on the age of the card. Others have reported trying the Xpert98 but I don't remember whether the reports were good or bad. Russ --upas-kwelspvbqvnazfwqvgicyftsho--
