Install AmigaOS 3.5/3.9
It is only allowed to either use OS3.5 or 3.9 on 1 Computer at the same time. Read the license carefully.
Booting off any Workbench ADF should be sufficient to install AmigaOS 3.5 or 3.9, make sure you have correct access to your CD-ROM drive (see below).
To install AmigaOS versions 3.5 and 3.9, you have to make sure you set the following options:
- CPU emulation set to 68020
- Kickstart ROM version 3.1
- Sound emulation enabled
Prepare emergency disk for CD-ROM access
Here we go:
- Boot your emulated Amiga with WinUAE and "insert" the ADF in a floppy drive
- Open the file devs/dosdrivers/emergency_CD on the disk with a texteditor
- Change the line device = "xxxxxx" to device = "uaescsi.device"
- Change UnitNum if needed
- Change the text MaxTransfer = xxxxxxx to MaxTransfer = 0xFFFF
If you get read/write errors from CD use a value of 0x1FFF instead
- Save the changed file to disk
Crashes during install?
Try changing the Sound options to a better level, e.g. 16 bit and 44.1 kHz; change the CPU settings to adjustable and level 1. Alternatively, remove the references to playing sounds (such as the clapping noise) from the installer script if you know what you are doing.
There is an update available for AmigaOS 3.9 called a Boing Bag and to get it to install on WinUAE you need a patch available from Amiga, Inc.
Installing OS3.9 using an AmiKit installation
If you don't have AmiKit, it is recommended to install it. This is the fastest way to get a working OS 3.9 installation.
- Boot from Host machine
- Copy kick.rom to AmiKit/ROMs folder
- Optionally, copy Picasso96.lha to AmiKit/RabbitHole folder
- Insert the OS 3.9 CD
- Run Amikit.exe program and click Configure to import AmigaOS files
- Select 1366x768 32bit screen mode
Hint: If you get CD read errors you need reduce the max transfer rate in your CD-ROM driver settings.
