Installation of AmigaOS 3.9 under WinUAE

Translated by Desolator. (


This is the “unofficial” english translation of Thomas Rapp’s guide on how to install AmigaOS3.9 under the WinUAE enviroment. I have asked Mr Rapp for approval of this document and he agreed that I could upload it to the net. (Just check Amiga.Org and you’ll see how many of the newbies there who have severe problems installing a fully functioning AmigaOS3.9 installation.) Also, I can’t speak german so this is freely translated, and not 100% accurate with Mr Rapp’s words. Also I’d like to add that running an Amiga in a emulated enviroment is NOT wrong to do. You real Amiga users (I run a real Amiga too though… :) should NOT look down upon those who choose the emulation as a way to run Amiga software. Most people I know that run WinUAE either get a real Amiga after a while or buy real Amiga software for the emulation enviroment. This is just one way of experiencing the Amiga Experience.

Setting up

You need a version of WinUAE, preferably the  latest, and kickstart 3.1 Roms & key.

Start WinUAE and make a new configuration. You can call it “AmigaOS39”.

Then, go into the harddrive setup part, and create the following harddrive directories:


The boot partition. Workbench will reside here after installation.


The Work partition. You install your additional software here.


This is where you copy the whole AOS39 cd-rom.


In the boot partition we have to create a startup-sequence so we can boot from it without a workbench installation.

Mr Rapp created a zip file with all the necessary files and I’ve uploaded it to my website. You can download it from

Copy the S catalogue from the Zip file to the WB39 harddrive, just as in the picture below.

It should look like this if you open it with an editor:

The .rexx script in the zip file goes into the root of the WB39 catalogue. (I.E D:\WinUAE\harddrives\WB39\CopyOS39.rexx.


Set the kickstart to 3.1

Don’t check the “Add PC Drives at Startup”. It just clutters up the workbench when we are going to install AOS39.

Add your CD-Rom drive by entering it’s drivemap letter. DON’T add the slash (/) at the end though, Amiga OS won’t recognize it if you do.

Configure the graphics settings like the picture below.

Set the CPU to 68020 and select "Fastest possible, but maintain Chipset" to get some speed.


Emulate 100% sound or the AmigaOS3.9 installation will hang and/or crash.

Save your configuration at this point.

Copying the AmigaOS3.9 CD.

Insert your AmigaOS3.9 CD into your CD drive.

In the shell window, enter the following command as showed below.

If it can’t copy the files, then readwrite the CD with this command which you type in the shell window.

protect AmigaOS3.9:#? +wd all

Then try again.


Start the OS3.9 Installation from the directory where you copied the AmigaOS3.9.

Select to create an Emergency disk.

When it asks for a disk just hit F-12 and select the Floppies Tab.

Push the “Create Standard Floppy” button,and type in a fitting name to your disk, such as Emergency. (you don’t need to type the .ADF ending)

When the disk is created, Don’t eject it but reboot the Amiga. (either by pressing CTRL+Windowskey + Windowskey or by pressing F-12, misc, and Reboot Amiga button)

This message will pop up as soon as the disk boots.

Just click ABORT and go into the workbench drawer, then prefs, then screenmode preferences.

Set the settings like this:

The Amiga dockbar don’t load  the correct setup so you can find the correct one in this directory: AmigaOS3.9:Emergency-Boot/Prefs/Env-Archive/SYS.

Select the Amidock window and select Edit Configuration in the menu (as shown below).

Now carry on with the installation.

On the question about graphics card, answer Yes.

After the installation is done, hit F-12, then the floppies tab and eject the emergency disk.

Reboot your Amiga and hopefully AmigaOS3.9 will load.

Click ABORT when the uae.device unit 3 window pops up.

remove from Devs/Dosdrivers the Emergency_CD icon since WinUAE can’t handle that.

You can install the internet software at this point if you like.

Installation of the Boingbag

Download the boingbag update from the internet, either by using Explorer in Windows or by installing the internet software and running Aweb from the Amiga enviroment.

Copy the Boingbag file into the Workbench Partition. The boingbag is LhA compressed so you have to go to Aminet and download it from there. Just search for

You need the AmigaOS3.9 cd-rom in the drive when you install the boingbag.

When you have aquired, place it in the Work: partition

Open up a shell window (right mouse button, choose execute command in the menu, type NEWSHELL)

Then do like this

cd work:

This is where we placed the file ram:

we install to RAM memory.

copy ram:lha c:

then we copy lha to the system itself.

lha x boingbag39-1

we unpack the boingbag.

Then we can proceed with installing the boingbag itself.

There! Now you got a working AmigaOS3.9 installed in WinUAE.

Installation of Picasso96

On the AmigaOS3.9 cd there is a picasso96 installer.

You’ll find it in the Contribution drawer. (as shown below)

The graphicscard uaegfx will automatically be recognized. Select it.

Reboot after the installation is done.

Swap out to Windows (yuck, puke!) and copy the rtg.library file which you can find in the Amiga Programs directory in WinUAE.

.¨..and place it into your Workbench harddrive under Libs\Picasso96 as shown below.

Now swap  into the Amiga enviroment again, and open up the screenmode preferences as before.

If it doesn’t look like the picture below, then reboot the Amiga and try again.

Select a screenresolution that fits your computer and your taste.


We got a fully functioning AmigaOS3.9 installation under WinUAE! Have extremely fun now with your Amiga!
