===Obscure, Abandoned, Beta or Experimental Operating Systems===

Despite many of the common operating systems including legacy ones such as MS-DOS, OS/2, Novell Netware, etc. are being supported by modern hypervisors, some obscure (e.g. [https://templeos.org/ TempleOS]), abandoned (e.g. [https://ja.wikipedia.org/wiki/%E8%B6%85%E6%BC%A2%E5%AD%97 Chokanji 1~4]), beta or experimental (e.g. [https://betawiki.net/wiki/Windows_95 Windows "Chicago" Beta]) operating systems may still fall out of the range and having issues, especially when relying on specific hardware configuration or old quirks that no longer presents in modern PC hardware.

Using a low-level [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#x86_CPUs|x86 CPUs]] emulator to run these operating systems may ease out such problems but its significantly slower performance compared to [[Wikipedia:X86_virtualization#Hardware-assisted_virtualization|hardware-assisted]] [[Hypervisors]].
