From: Joe Schweier on 9 Nov 2009 12:49 I have heard that there is some software out there that will let you emulate other OSes under linux... eg os2 Will I need to hunt down the OS2 drivers for the network card on this computer, I ndon't think it'll be out, or does the "software" emulate the network card for OS2?? Thanx Joe

It depends on what you mean by "emulate". There is a software package available for Linux (and other x86 Unix systems) that "emulates" Microsoft Windows. This package (called "Wine") runs MSWindows programs inside itself (a simplified description, to be sure) and provides a layer that translates the program's calls to MSWindows interfaces into calls to Linux interfaces. With Wine, you do not install a Windows OS, but you still can run Windows programs. I do not know of any comparable emulator for OS2. If this isn't what you mean, then perhaps you are referring to the various "virtualizers" available. These applications (like QEMU, Xen, and VMWorks) create a "virtual CPU" with "virtual memory" and "virtual devices". Within this virtual world, you can then run real operating systems. With these "virtualizers", you get a system-within-a-system. It is possible to load the real OS2 into such a virtual environment, and use it as if it were running on a separate, real computer. > Will I need to hunt down the OS2 drivers for the network card on this > computer, I ndon't think it'll be out, or does the "software" emulate the network > card for OS2?? Usually, the "virtualized environment" contains an emulation of a very common network card, one that any operating system built in the last 15 years would have support for. HTH

I have not heard of an OS/2 ABI for UNIX yet, but it's possible that it exists. However, as others have said, there is also /Wine/ which is a Windows ABI on top of UNIX - and as such, only sort of an emulator, since it doesn't emulate a computer but simply supports the running of Windows-specific applications on top of a UNIX operating system - and there is DOSemu, which emulates a DOS computer but does require a DOS operating system - usually this is FreeDOS. In this case, there is mention of true emulation as DOSemu also emulates the processor in software. That said, there is of course such a thing as virtualization, and various solutions to that end exist. For instance, there are the virtual machine monitors (like VMWare or VirtualBox, or the Linux Kernel Virtual Machine, which works with the Qemu virtual machine monitor), which run inside the host operating system as a process and which emulate a complete PC - with or without hardware support for the virtual machine - and then there is Xen, which is a hypervisor that runs underneath all operating systems on the machine - so there is no "host", but instead there is a "privileged guest". Xen supports full virtualization if the machine has hardware virtualization extensions - most if not all modern machines do - and as such, it /should/ allow for running an unmodified OS/2 guest inside a virtual machine alongside of the privileged guest. > Will I need to hunt down the OS2 drivers for the network card on this > computer, Normally not. In the event of Xen, the hypervisor emulates a couple of very common network adapters (and some other common hardware), which your OS/2 would then be able to use, provided that OS/2 natively has drivers for those particular adapter types, of course. The emulated network adapters Xen presents to a hardware virtual machine are - according to Wikipedia - a Realtek 8139 and an Intel(?) NE2000. With regard to virtual machine monitor software like VirtualBox or VMWare, I'm not sure what hardware they present to the guest operating system, but perhaps you can consult the homepages of those respective projects to find out. With regard the Qemu it's the same as with Xen, since Xen uses the Qemu device manager for hardware-assisted virtualization. > I ndon't think it'll be out, or does the "software" emulate the > network card for OS2??

In KVM you can select different cards to emulate. You need to check which network card(s) the emulator you select do emulate. -- //Aho |
