553 kexec is a system call that implements the ability to shutdown your
554 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400555 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800556 you can start any kernel with it, not just Linux.
557
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400558 The name comes from the similarity to the exec system call.

592 that may need to compute untrusted bytecode during their

691 Selecting this option will wakeup the User Break Controller (UBC) on
692 startup. Although the UBC is left in an awake state when the processor
693 comes up, some boot loaders misbehave by putting the UBC to sleep in a
694 power saving state, which causes issues with things like ptrace().

717 help
718 The Maple Bus is SEGA's serial communication bus for peripherals
719 on the Dreamcast. Without this bus support you won't be able to
720 get your Dreamcast keyboard etc to work, so most users
721 probably want to say 'Y' here, unless you are only using the
722 Dreamcast with a serial line terminal or a remote network
723 connection.
