Virtual 8086 Mode - 64-bit Support

64-bit Support

Support for Virtual 8086 mode is not available in x86-64 Long Mode, although it is still present on 64-bit capable processors running in 32-bit protected mode. The removal of this sub-mode means that 16-bit compatibility must be rewritten or removed from 64-bit operating systems. For example, DOS and 16-bit Windows application support is not present in x64 editions of Windows, necessitating the use of 3rd party emulation software such as DOSBox.

Famous quotes containing the word support:

    There is much to support the view that it is clothes that wear us, and not we, them; we may make them take the mould of arm or breast, but they mould our hearts, our brains, our tongues to their liking.
    Virginia Woolf (1882–1941)
