 445           If you say N here, the kernel will run on single and multiprocessor
 446           machines, but will use only one CPU of a multiprocessor machine. If
 447           you say Y here, the kernel will run on many, but not all,
 448           singleprocessor machines. On a singleprocessor machine, the kernel
 449           will run faster if you say N here.
 450
 451           People using multiprocessor machines who say Y here should also say
 452           Y to "Enhanced Real Time Clock Support", below.

 546           inside your box.  Other bus systems are PCI, EISA, MicroChannel
 547           (MCA) or VESA.  ISA is an older system, now being displaced by PCI;

 557           bus while maintaining backward compatibility with cards made for
 558           the older ISA bus.  The EISA bus saw limited use between 1988 and
