458 kexec is a system call that implements the ability to shutdown your

460 but it is independent of the system firmware. And like a reboot
461 you can start any kernel with it, not just Linux.
462

464
465 It is an ongoing process to be certain the hardware in a machine
466 is properly shutdown, so do not be surprised if this code does not
467 initially work for you. It may help to enable device hotplugging

642 help
643 The Maple Bus is SEGA's serial communication bus for peripherals
644 on the Dreamcast. Without this bus support you won't be able to
645 get your Dreamcast keyboard etc to work, so most users
646 probably want to say 'Y' here, unless you are only using the
647 Dreamcast with a serial line terminal or a remote network
648 connection.

654 Compact Flash is a small, removable mass storage device introduced
655 in 1994 originally as a PCMCIA device. If you say `Y' here, you
656 compile in support for Compact Flash devices directly connected to
657 a SuperH processor. A Compact Flash FAQ is available at
658 <http://www.compactflash.org/faqs/faq.htm>.

660 If your board has "Directly Connected" CompactFlash at area 5 or 6,
661 you may want to enable this option. Then, you can use CF as
662 primary IDE drive (only tested for SanDisk).

677 - "Area5" if CompactFlash is connected to Area 5 (0x14000000)
