"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.

|

kexec is a system call that implements the ability to shutdown your
|
|
current kernel, and to start another kernel. It is like a reboot
|
|
but it is independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity to the exec system call.
|
|
|
|
It is an ongoing process to be certain the hardware in a machine
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
initially work for you. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is

strongly in flux, so no good recommendation can be made.

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

The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
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.
|
|
|
|
Say Y here if you are building a kernel for an EISA-based machine.
|
|
|
|
Otherwise, say N.

MicroChannel Architecture is found in some IBM PS/2 machines and
|
|
laptops. It is a bus system similar to PCI or ISA. See
|
|
<file:Documentation/mca.txt> (and especially the web page given
|
|
there) before attempting to build an MCA bus kernel.
