Just to pick at a nit, BIOSs were, and still are, hardware vendor
specific. It was a well defined software interface to the BIOS that
allowed MS-DOS, CPM-86, and other O/S's to run (or at least boot) on
generic PC platforms.
IBM never bothered to copyright the PC BIOS interface because they
thought that even if clone vendors were to pop up, IBM would still be
able to beat them price by virtue of their own economy of scale. What
IBM didn't foresee, was the advent of low cost chip sets that became
fundamental in driving down the cost of PCs.
