Okay, that makes sense. The startup code tries making some INTn calls to size memory. If DOS happens to hook the interrupt vector, then the INTn call will try to jump to what it thinks is a DOS routine in low memory, which fails. Hmm.

That works, since it doesn't patch the real-mode interrupt vectors. > I found that I could successfully boot my kernel built from CTM > src-cur 3287 sources (~Mar 22 which *does* include options VM86).
