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:
“I believe, as Maori people do, that children should have more adults in their lives than just their mothers and fathers. Children need more than one or two positive role models. It is in your children’s best interest that you help them cultivate a support system that extends beyond their immediate family.”
—Stephanie Marston (20th century)
