| |
| 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 |

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

| If unsure, say N. |

| Find out whether you have ISA slots on your motherboard. ISA is the |
| name of a bus system, i.e. the way the CPU talks to the other stuff |
| inside your box. Other bus systems are PCI, EISA, MicroChannel |
| (MCA) or VESA. ISA is an older system, now being displaced by PCI; |
| newer boards don't support it. If you have ISA, say Y, otherwise N. |
| |
| config EISA |
| bool |
| ---help--- |
| 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. |
| |
| config MCA |
| bool |
| help |
| 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. |

| The Maple Bus is SEGA's serial communication bus for peripherals |

| get your Dreamcast keyboard etc to work, so most users |
| probably want to say 'Y' here, unless you are only using the |
