Virtual-86 Mode
From Higher Intellect Vintage Wiki
One of the operating modes of the 80386 and 80486 processors in which user programs run as if the CPU were in Real Mode, while providing the protection and address-mapping capabilities of Protected Mode to a supervisor program which oversees the virtual machine on which the user programs are running. This mode is called Virtual-86 because one or more virtual 8086 environments are run on a single CPU. See also Protected Mode, Real Mode, Virtual Machine.
