Windows "The 16-bit Windows kernel was actually three kernels. One if you were using an 8086 processor, another if you were using an 80286 processor, and a third if you were using an 80386 processor. The 8086 kernel was a completely separate beast, but the 80286 and 80386 kernels shared a lot of code in common." As always, Raymond Chen delivers. If you don't yet follow his blog, you should.

Yeah, I was floored when I found out that you couldn't switch out of protected mode on the 286. I think they really learned their compatibility lesson with that, because almost all processors afterwards have been great at adding new features and modes without destroying the ability to use legacy software. DOS still boots on modern processors.
