Hi, I tried installing OS 3.9, and it's really not that difficult. These guides on the web makes it seem more difficult than it really is. -And the installation is not required to be run from an actual CD, whether it's a real CD or CD image.

So here are some high-level instructions written from memory (this is not the only way):

Part A: Preparation

Create a directory somewhere on your computer called AmigaOS3.9 and copy everything from the AmigaOS installation to this directory.

Create an ADF file to contain the rescue / installation floppy. You can just make a copy of any existing floppy (the contents will be overwritten anyway) and call it for example rescue.adf.

Part A: Create an OS 3.9 installation / rescue floppy

Use the following media:
- floppy drive 0: workbench boot disk
- floppy drive 1: the rescue adf.
- hard drive 0: path to AmigaOS3.9 directory (where you copied the installation).

You let the system boot from the WB disk, run the installer from the AmigaOS3.9 volume and create a boot/rescue install disk (whatever it was called) and choose to create the floppy in drive DF1:

After this is done you can shut down FS-UAE.

Part B: Install OS 3.9

Use the following media:
- floppy drive 0: the rescue adf (you will boot from this)
- hard drive 0: the drive you want to install to (HDF or directory, your choice).
- hard drive 1: path to AmigaOS3.9 directory (where you copied the installation).

When you start FS-UAE, you'll boot into workbench, and you can once again start the installer from the AmigaOS3.9 volume. This time you choose full install. -Assuming hard drive 0 contains the volume you want to install to, for example Workbench, you simply select this when the installer asks you where to install to.

With these instructions you don't use the CD directly, so no cdrom_image_0 or hard_drive_x pointing to /dev/disk... -But see Toni's warning later down. Alternatively, if you create an ISO image of the CD somehow, you can use this image with cdrom_drive_0 instead.
