Hardware / Re: The last nail in OS/2's coffin

Currently, this is only a proposal. But it gives a very good idea of what Intel thinks is no longer needed.
Its expected this will indeed be long term thing to happen. I understand the legacy bit takes up 12% of the space in CPU.
I read an article (I do not the have link handy) of one of the main AMD tech engineers and he said the proposal was every interesting.
However the engineer indicated the changes proposed are "very, very, very, very complex to make".
The other thing that this would imply is (the way I understand it) is that NO current VM would work anymore
to run legacy OS. Its the CPU that provides the virtualization support to hypervisor.

Correct. Virtualization of OS/2 (and likewise: DOS and Windows 16-bit) will not be possible once x86-S is introduced. Only emulation will be possible (with a huge performance impact, of course).
