How to install OS4.1 Classic

After dozens of attempts to install AmigaOS4.1 Classic the best way
possible, I have it down to a science. Below are the steps I take to
set up my configuration.

I use an ISO of the CD so it doesn't get scratched from use and is
easier to have it on my harddrive. Using ISOs will also be the way you
import files/programs to OS4.1 so get used to using them.

In my WinUAE folder I have theses folders: ADFs, Configurations,
HDD_CDROM, HDFs, ISOs, KickstartDiscs, ROMs, SaveStates, Screenshots.
Keep your files organized.

From TheZone download the archive I made:

Or from my public DropBox if not there

This has my configuration file and BinoX's Guide-Files.adf with the files
already extracted. It also has the missing update.library that is needed
after you install the Update packages and the Updater gets updated.
It goes in LIBS:. It also has ZorRAM set up for the SWAP partition.

Copy the Configuration, ADFs, and ROMs to their respective folders in
your WinUAE folder. Start WinUAE and pick and load the OS4.1 Classics

You will have to edit the paths to match your drive layout for the ROMs
and ADF. Keep the filenames the same.


Once you have all of the paths set, make sure the boot floppy is inserted.

Goto "CD & Hard drives".
Make the Workbench boot partition:
Add Hardfile...
3990 MB or less.
(4000 is the maximum you can use for the Workbench boot partition.)
(4000 may not work sometimes. Just use a little less.)
Check "Dynamic HDF".
In the drop down pick "Custom".
Enter 0x53465302 for "DOS type".
Switch to HDFs folder and give it name. ex: AmigaOS4.1.vhd or Workbench.vhd
"HD Controller" to: Accelerator board SCSI.
Device 0.
Click "Enable RDB mode".

Make the Work partition:
Add Hardfile...
Give it a size. I use 8000.
Check "Dynamic HDF".
In the drop down pick "Custom".
Enter 0x53465302 for "DOS type".
Give it a name. ex: Work.vhd
Change device number to 1.
Uncheck "Bootable".
Click "Enable RDB mode".

Add more partitions the same way if you need them. I have a separate one
for my Programming.

Add the CD drive:
Click "Add SCSI/IDE CD Drive".
HD Controller to: Accelerator board SCSI
Device number to 6. (I like it at the end)

If the path for the CD drive/image is incorrect, "Select image file"
and pick your ISO.

Save the configuration.



Once the installer is loaded, click on "Start the Hard Disk preperation
You want "cybppc.device".
Click your Workbench partition. (First one you made)
No changes.
Edit partitions and filesystems.
Add partition.
Add, remove or edit filesystems.
Add new FS.
Pick "SmartFileSystem".
Change DosType to: 53465302
Check "Bootable".
Select filesystem/edit details.
In drop down pick "SFS\02".
Change "Blocksize" to 512.
Save to disk.
Yes, save.

Pick Work.vhd.
Repeat the same steps but do NOT tick Bootable.

Repeat for any other partition(s).

Close window.
Yes, REBOOT now.


Click "Set the Location and Keymap".
Pick your Language, Country, and Time zone.
Since using WinUAE, un-check "Amiga keyboard".

Click "Start the AmigaOS 4.1 installation utility".
Check the box.
Leave at "Amiga 4000".
Format disk(s).
Pick (DH0).
Name it: Workbench.
I leave the Trashcan ticked.
Quick Format.
Repeat for Work partition.
I un-tick the Trashcan for all other partitions.
Next when done with partitons.

Keep at DH0:.

Pick Picasso IV.
Keep "Include Boot VGA" ticked.
Pick you maximum monitor resolution.

Don't change anything else. Just keep clicking Next and the
installation will start. It goes pretty quick.

Return to welcome menu.
F12 and Quit.

Restart WinUAE.
Pick "OS4.1 Classics". (not double click)
Eject the floppy.
Eject the CD.
Save configuration.


Once Workbench is loaded,
Adjust screen settings.
Pick the maximum resolution that is BGR24.
Test it just in case.

Close the window.


Open a Shell window from the Docky.

Insert the "Guide-Files.adf" from the my archive.

copy df0:lha C:
copy df0:ethernet.device Devs:Networks/
copy df0:wget c:

Close the Shell.


Now lets install the network driver.

On the Docky bar click "Internet Wizard".
Local Area Network.
Manual configuration.
Select "Commodore A2065" in the list.
Click the file picker gadget to the right of "Name".
Navigate to "Devs:Networks" and pick the "ethernet.device".
Test this configuration.
It should say it passed.
No changes.
Close the Shell window.

To verify you have a good connection:

Open a Shell window from the Docky.
Make it full height.
Type in:
wget -O aiss.lha
It will save to to Workbench:
Move it to Work:.
Close Shell window.
Open Work: and double click aiss.lha to extract to Work:.
Install it.


Register your AmigaOS 4.1 Classic at
YOU MUST DO THIS!!!! You will need your username and password below.

Once registered goto the Downloads page, AmigaOS 4.x, AmigaOS 4.1 Updates.
Download the 4 updates.
Create an ISO with them.
Insert the CD (ISO).
Double click on each one to extract to Work:.
Install each update with a reboot in between.
NOTE: It probably won't soft reboot, so F12 and Restart or Quit.
NOTE: Installing "Run In UAE" is optional and can be done later. I would
wait until after everything is up and running. It can be a pain to install.
It also asks if you are WHLoad registered and will need the key if you are.
Put it on a floppy (adf).

After Update 6 you now have AmiUpdate. It is in Workbench:System folder.
Run it.
There will be a newer version. Install it.
You get an error message:
"Failed to open update.library 53.13+".
Close "AmiUpdate".
Insert "Guide-Files.adf".
Open a Shell window.
Copy df0:update.library LIBS:
F12 and Restart.
Run "AmiUpdate" again and download new version again.
Enter your username and password you created at
Do all the updates.
Scan and Update again.
Reboot after each batch update.
You might get an error, just hit OK and continue.
Some apps will have a warning, go ahead and install them.
A few apps require manual updating. Goto RAM:Unpacked and do them manually.
They will keep showing as needed until you do it manually.


Now let's fix the intro sound playing twice.

Notepad in the Docky.
Put a ; in front of the line:
Run >NIL: *>NIL: SoundPlayer QUIET


Put the installation CD (ISO) back in.
Extras Installer.
Install them all if you like.
Origyn Web Browser is nice.


That's it! Enjoy your new installation of AmigaOS 4.1 Classic!
