[Edit]1 QEMU for MacOS X

QEMU is a Free Open-Source Emulator for all kind of Computers. Unlike Virtual Box, QEMU emulates the CPU itself and can therefore run on any Guest Operating System on any Host Operating System, and do not require a i386 compatible CPU.

Why MacOS X? Why not Windows XP, Vista or Linux?

It is also possible to install OS/2 under Windows XP or Vista using QEMU or QEMU-Manager. I use MacOS X because i have a Mac (iMac G3/350) and because it is by far the easiest way to run OS/2 in a virtual Environment. MacOS X has some unique features that increases the useablity of OS/2 inside a virtual Machine.

The first is the possiblity to mount disk-images of any kind under MacOS X. In fact, Linux has the same functionality with the feature of the loop-back Device. But to explain to you what this is, i have to write many pages and then you still have to read the recomended Manual-pages to understand how to handle Loop-Back devices. For MacOS X you simple klick on your disk-image Icon. Thats it! Nothing more to talk or think about. It works, it doesn´t matter how it works, it just works and it works absolutly perfectly.

The second one is the MacOS X System Disk-Tool. With this tool, you can create Images of any kind of Media. You can make an Image of you OS/2 Warp Installation CD. You can make an Image of an Harddisk where you have installed a native Version of OS/2. You can do this with just 2 to 3 Mouse-Clicks. And again, It works, it doesn´t matter how it works, it just works and it works absolutly perfectly. You don´t have to install additional software like Nero or Toast.

The third and most important is Q. This is a graphical fronded for QEMU, which makes it possible to configure a virtual machine in a few secounds. QEmuManager of Windows and KQEmu of Linux are similar but not as easy to install and not as easy to handle as Q. The only disadvantage is, that QEmu-Manager has the feature to use a physical harddrive instead of a virtual Diskimage, and Q not. This feature is very nice, because you can install an Operationg System inside a virtual machine onto a physical drive like an Memorystick of USB-Drive. After the installation is complete, you can remove the physical drive and plug it into another Computer and boot the OS nativly form that drive.

What do i need to install OS/2 under Q?

You need a Mac with at least a G3 Processor and MacOS X Verion 10.4 (Tiger). You also need the Virtual Machine Q and the Installation CD of the OS you want to install. At the Moment, it is possible to run the following OS/2 Versions on Q:

• OS/2 2.1
• OS/2 Warp 3
• OS/2 Warp 3 Connect
• OS/2 Warp 4 up to Fixpack 12

At the Moment, it is not possible to install any earlier or newer Version than these on QEMU. On all Versions, OS/2 runs with:

• VGA resolution of 640 x 480 with 16 Colors
• SoundBlaster 16 Sound
• HPFS Filesystem
• AMD PCnet Ethernet PCI

Because there is currently no working Display Driver for the Cirrus Logic 5446 Chipset, there is no greater display-resolution than 640 x 480 possible. Any Version of Scitek Display Doctor or SNAP will hang the System at GUI startup.

On the Macintosh a special Version of the Emulator QEmu is used that is called Q - [kju:] http://www.kju-app.org (http://www.kju-app.org/). You have to download the Application and create a new Guest PC. Choose a Name and select as Operating System: "Q Standard Guest". In the General Setup select the Hardware Menue and choose the following Settings for that Guest-PC:

If you set this up, press the (Create PC) Button and Q will create a new QEmu GuestPC File in your Home-Directory. You can change this settings at anytime the GuestPC is not running. These settings are valid for all OS/2 Versions. Remember that early OS/2 Versions have problems with large Harddisks, so it is wise to start with a "small" System-Harddisk. You can connect up to 3 additional virtual Harddisks to the Guest-PC later if you need more Drivespace. Now you are ready to install OS/2 into the GuestPC.
