11 | only select this option if you have hardware that actually has a | |
12 | 64-bit processor and if your application will actually benefit from | |
13 | 64-bit processing, otherwise say N. You must say Y for kernels for | |

1096 | The frame buffer device provides an abstraction for the graphics | |
1097 | hardware. It represents the frame buffer of some video hardware and | |
1098 | allows application software to access the graphics hardware through | |
1099 | a well-defined interface, so the software doesn't need to know | |
1100 | anything about the low-level (hardware register) stuff. | |
1101 | ||
1102 | Frame buffer devices work identically across the different | |
1103 | architectures supported by Linux and make the implementation of | |
1104 | application programs easier and more portable; at this point, an X | |
1105 | server exists which uses the frame buffer device exclusively. | |
1106 | On several non-X86 architectures, the frame buffer device is the | |
1107 | only way to use the graphics hardware. | |
1108 | ||
1109 | The device is accessed through special device nodes, usually located | |
1110 | in the /dev directory, i.e. /dev/fb*. | |
1111 | ||
1112 | You need an utility program called fbset to make full use of frame | |
1113 | buffer devices. Please read <file:Documentation/fb/framebuffer.txt> | |
1114 | and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto> | |

1523 | The Extended Industry Standard Architecture (EISA) bus was | |
1524 | developed as an open alternative to the IBM MicroChannel bus. | |

1527 | bus while maintaining backward compatibility with cards made for | |

1529 | 1995 when it was made obsolete by the PCI bus. | |
