I suspect he was more afraid of boot sector viruses than of Linux.

Intel would be making a MAJOR mistake if they lost binary compatibility ---
and you may be certain that they know it (why else does the 486 boot up in
8088-compatible mode?). Although I do wonder about the write-behind memory
cache: sounds like a good way to screw up access to memory-mapped controllers
to me. Would this have to be disabled globally on systems not rewritten for
the Pentium to disable it for those devices only?

It's not too late to turn back from the "Gates" of Hell... Linux: the FREE 32-bit operating system, available NOW. Why waaaaaait for NT?
