VMware Workstation 3.2
Before installing the operating system, be sure that you have already created a directory for the new virtual machine and configured it using the VMware Workstation New Virtual Machine Wizard (on Windows hosts) or Configuration Wizard (on Linux hosts).
You can install MS-DOS 6.22 inside a virtual machine using the Microsoft full-version MS-DOS installation disks. If you have the upgrade disks, you must install an earlier version of DOS before you upgrade. To start installing MS-DOS 6.22, put the first disk in the floppy drive, power on the virtual machine and follow the instructions on the screen.
After you install DOS, VMware recommends that you install a CPU idle program within the virtual machine. Most versions of DOS do not idle the CPU when they are idle. Therefore, when you are running DOS in a virtual machine, the virtual machine takes up CPU time on the host even when DOS is idle. VMware Workstation relies on the guest operating system to use the Halt instruction or advanced power management to deschedule the virtual machine when it is idle.
We have tested a program called DOSIDLE.EXE and have found it works successfully with VMware Workstation. It can be downloaded from
Follow the instructions provided with the DOSIDLE.EXE program. But be aware of the -cpu option, which causes the idle program to access the CPU at a low level in order to optimize performance. There is a good chance that this will not work with some CPUs under VMware Workstation. VMware suggests that you not use it.
You can install Windows 3.1x using the standard installation disks. VMware Workstation virtual machines support the networking features found in Windows 3.11 (or Windows for Workgroups). If you set up networking, choose the Advanced Micro Devices PCNET Family (NDIS2/NDIS3) Ethernet driver.
The current support for DOS/EMM386 is limited. We recommend that you avoid using it for now. Be sure to comment out the entry in the CONFIG.SYS file.
We intermittently encounter erratic mouse behavior in virtual machines running Windows v3.1x in window mode. This problem does not appear in the full screen mode.
No VMware Tools package exists for DOS or Windows 3.1x guest operating systems; therefore, Windows 3.1x is limited to VGA mode graphics and you must always use the Ctrl-Alt key combination to release the mouse from a DOS or Windows 3.1x virtual machine.
On a Linux host with an XFree86 3.x X server, it is best not to run a screen saver in the guest operating system. Guest screen savers that demand a lot of processing power can cause the X server on the host to freeze.
