"Bare CPU" aka "unknown" means an SH-based system which is not one

of the specific ones mentioned above, which means you need to enter
|
|
all sorts of stuff like CONFIG_MEMORY_START because the config
|
|
system doesn't already know what it is. You get a machine vector

without any platform-specific code in it, so things like the RTC may

not work.

you have a system with more than one CPU, say Y.

singleprocessor machines. On a singleprocessor machine, the kernel

Find out whether you have ISA slots on your motherboard. ISA is the

newer boards don't support it. If you have ISA, say Y, otherwise N.

The Extended Industry Standard Architecture (EISA) bus was

The EISA bus provided some of the features of the IBM MicroChannel

bus while maintaining backward compatibility with cards made for

the older ISA bus. The EISA bus saw limited use between 1988 and

1995 when it was made obsolete by the PCI bus.
