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.

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.
