When I saw that WinUAE was to the point of actually installing OS4.1 Classic, I immediately put in an order to AmigaKit.com to get my copy. I ordered on Friday and it arrived Monday, just 3 days later. That’s UK->US in 3 days and I didn’t specify rush shipping at all! Good job AmigaKit!
The disc was actually the base install with Update 2 integrated (there have been 6 updates, plus the AmiUpdates that have been online only since update6). I first made an ISO as I find that is much easier than using a real disc with WinUAE.
Just setting up, I had to do the following:
Got the latest “official” beta version of WinUAE (not the quick fixes he posts sometimes). At the time of this writing, it was WinUAE_2900b12 (from this post): http://eab.abime.net/showpost.php?p=970403&postcount=481 There may be a newer one by the time you read this.
Then, I had to download the PowerPC ROMs from the Zone! area on EAB. Just go to eab.abime.net, do a search for getting access to the zone. The file was called accelerator_roms.zip by Toni Wilen. Extract this to the same place where the normal Amiga ROMs go. I also copied the 44.69 version of both blizzardPPC and cyberStormPPC files to ones without the version (i.e. bizzardppc.rom and cyberstormppc.rom). Also, go –> here , to download the file called PIV_FlashImage74.zip, extract the single file in it, copy to the same roms folder as the rest, and rename the bin file to “picasso_iv_flash.rom.
Now, go to this thread here here <– and follow the Guide exactly. This was written for OS4.0 but I found it worked with OS4.1.
The only difference I found was that I unchecked the JIT Z3 memory option in the RAM section. I had read that it was very problematic in earlier versions of WinUAE.
Here are some pictures of my boot / install screens:
I missed the part about skipping the “Run Media Toolbox” and “Format Disk(s)” screen and clicked the Media Toolbox button. The emulation just sat there so I reset WinUAE and when I started back into the install, I got an RTG screen which was much easier on the eyes. Here are some images for the final stages of the install
Install took a VERY long time.
In the end, I had my AmigaOS4.1 Classic emulated environment. After the initial install, I shut down WinUAE and made a backup copy of the hdf file in case something messed up later. That install took too long to do again.
Now, I need to test what does and doesn’t work, as well as patiently wait for Toni to get the JIT QEMU PPC Core replacement so we can see some real speed! [This version seems a bit fragile so far]
Good Job Toni and Hyperion!

Excellent guide to installing AmigaOS 4.1 Classic on WinUAE! Must read!
How did you manage to transfer the boot floppy to your WinUAE system?
There is an adf of the boot floppy on the CD. Just copied that to my windows hard drive and selected it for the df0 drive for the install
Ok, found the MakeBootFloppy skript on my OS4.0 Classic CD and created the boot floppy.
Now I am waiting for the intial screen and it really takes a long time for the black screen to disappear…
You don’t need the script…. in the base of the AmigaOS4.1Classic CD, there is a folder called BootFloppy. Inside of that, there is an lha compressed version of the ADF you want.
The filename is Boot_Floppy.adf.lha
Just extract that to your windows side somewhere. I use WinRAR and it can extract from an lha file.
How did you manage to transfer the boot floppy image to your WinUAE system?
Did you get networking/internet accerss working?
If so, can you provide a few screen captures explaining what’s required?
I will be making an updated post soon that will include networking details as well as updates to making it run full screen, hi-rez on my laptop.
Thanks for reading!
It would be nice if you put ISO of the AmigaOS4.1 Classic.
Os4.1 FE is like $30USD. Affordable enough for anyone these days unlike way back when it was $100+
Can you tell me how to use CD under UAE? I technically know how to do it, but it doesn’t work!? PLEASE!
Sorry for the late response. I have yet to jump back into OS4.x emulation world. I know others have figured out how to make dynamic CD loading work, but the last time I tried, I just had to make an ISO image of the CD / DVD I wanted to load up, add it in WinUAE as an image on the built-in Cyberstorm SCSI accelerator port number 1 (number 0 was the harddrive image). I then had to start the system again and it was there when it came up. Toni Wilen is working on a new UAE harddrive controller that works with folders on the native Windows side that should allow better flexibility than ISO images. I haven’t checked into it in a while Check on eab.abime.net under the WinUAE support forum. V3.3.0.0 is where the experimentation is happening.
