508 you can start any kernel with it, not just Linux.

514 initially work for you. It may help to enable device hotplugging

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

680 The Maple Bus is SEGA's serial communication bus for peripherals
681 on the Dreamcast. Without this bus support you won't be able to
682 get your Dreamcast keyboard etc to work, so most users
683 probably want to say 'Y' here, unless you are only using the
684 Dreamcast with a serial line terminal or a remote network
685 connection.

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

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