emulating Amiga OS 4.1 with fs-uae under linux – preparing the host – going further – conclusions and limitations

Why this tutorial ?

I’ve seen many tutos on emulating Amiga OS 4 with WinUAE under Windows, but not under linux, which needs some preparation, the installation of dependencies, and the QEMU module. Thanks to Stéphane L. and Serge A. from the Facebook group “Amiga (only) pour toujours and beyond” for discussing around this subject.

Prerequisites

You must have FS-UAE installed on your machine. I won’t enter into the details of its installation. If you want to install it onto Ubuntu, just get to this page :

https://fs-uae.net/download#ubuntu

You also need ROMS and Amiga OS 4 itself. For the ROMS, the most simple is Amiga Forever :

For Amiga OS 4, get it in your preferred shop :

Preparing your host

You tutorial is available below. It represents a lot of work and time, please, show me your support in registering below. I’ll send you from time to time (once a month max) the last news about my music and my amiga projects.

And then you can see that the machine starts like hell.

Amiga OS CDROM running

Installation of Amiga OS 4.1 :

Next step is the Amiga OS 4.1 installation itself. In order this article not to be too long, i’ve described it in this article :

Install Amiga OS 4.1 process

Installation ended, Amiga OS 4 is finally installed :

Tadaaaa !

tadaaaaa !

Network configuration

Final step is to configure network. It is also described in an other article :

Amiga OS 4.1 emulated network settings

Finalisation

You must install the updates and the “extras”.

First ones are available for registered users, the second ones are on the Amiga OS DVD.

Wazp3D

Warp3D compatible libraries, that does 100% processor, which can be very usefull on emulation. They can be downloaded from here : http://aminet.net/package/driver/video/Wazp3D Original project webpage : http://thellier.free.fr/Wazp3D.htm Thanks to Serge A. for links and informations. He pointed me a very interesting thread about Wazp3D on Amiga-NG.ORG forum : https://www.amiga-ng.org/viewtopic.php?topic=1926&forum=8&start=150

Going further :

Personnally, I like that my emulation starts by itself from the power button of the computer. Most of all, I have THE box for it : The X500+ box. I really think i’m on a real one.

my so wonderfull X500+ box for my emulated amiga 4000

Here is the video wich shows what it gives :

If you wanna know how to do, and if you have the “DIY” spirit (“Do It Yourself”), you can read thoses articles :
  • To create the environnement with ubuntu server and openbox, that boots really fast (here it is an amiga os 3, but you just need to replace the configuration name in the autostart, and bingo, you have an amiga OS 4 wich boots by itself)

Emulate your Amiga on linux that boots fast and gets to the workbench automatically

  • Et pour améliorer le rendu, remplacer les logos de démarrage du grub et d’Ubuntu par la boing ball :

Change the boot and grub logo of linux for a boing ball

Conclusions / Limitations :

So well… I’ve been disapointed by those points : 1-speed : it’s usable, but try to launch a module under milkytracker and move a workbench window, the sound… cracks and isn’t fluid. From a general point of view, the system is slow, far from from what I wait of an Amiga OS. 2-impossible to share host folders : we can’t mount an host folder with QEMU… To share datas with outside world you must then get through an émulated Amiga OS 3 and write to a HDF that you mount after into Amiga OS 4. It’ a bit long and annoying. 3-memory limitations to PPC 128Meg and the imposibility to use FAST RAM extensions : this is limitating. Amiga OS 4 uses the half of it after launched. It lets only 64 Meg to work... 4-green screen : after booting my machine and making it autostart from power button, i get a green screen and have to cold reset the amiga to make it work. This does not do that when I launch fs-uae for the first time in the session. Maybe some QEMU strange stuff. 5-a very good way to discover but… My conclusion is that emulating Amiga OS 4 is a very good way to discover it because it’s genious OS, but… i’ll stay on my emulated OS Amiga OS 3.1 / 68060 / 8Meg Chip / 1Gig de Fast, which lets me launch Haujobb demos without problem.
