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.

moondevil,

"This was only required if you needed to start a MS-DOS program from inside Windows. Otherwise it was running in full 16 bit protected mode with all required features."

Yes of course, software could be built for the 16bit protected mode. If you want to say the 286 was capable of multi-tasking, then I'll have to admit that it's technically true, but it required all software to be rewritten for it. The 386 was intel's first processor suited for general purpose multi-tasking, that's my opinion anyways because the 286 needed external chipset logic to continuously reset itself into real mode to run the majority of software avaiable at the time.

Xenix executed in protected mode without any need of real mode.
