12 | The Extended Industry Standard Architecture (EISA) bus was | |
13 | developed as an open alternative to the IBM MicroChannel bus. | |
14 | ||
15 | The EISA bus provided some of the features of the IBM MicroChannel | |
16 | bus while maintaining backward compatibility with cards made for | |
17 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
18 | 1995 when it was made obsolete by the PCI bus. | |
19 | ||
20 | Say Y here if you are building a kernel for an EISA-based machine. | |
21 | ||
22 | Otherwise, say N. | |

28 | ---help--- | |
29 | Activate this option if your system contains a Vesa Local | |
30 | Bus (VLB) card that identify itself as an EISA card (such as | |
31 | the Adaptec AHA-284x). | |
32 | ||
33 | When in doubt, say N. | |

38 | default y | |
39 | ---help--- | |
40 | Activate this option if your system contains a PCI to EISA | |
41 | bridge. If your system have both PCI and EISA slots, you | |
42 | certainly need this option. | |
43 | ||
44 | When in doubt, say Y. | |

1da177e4 LT |
52 | default y |
53 | ---help--- | |
54 | Activate this option if your system only have EISA bus | |
55 | (no PCI slots). The Alpha Jensen is an example of such | |
56 | a system. | |
57 | ||
58 | When in doubt, say Y. | |

60 | config EISA_NAMES | |
61 | bool "EISA device name database" | |
62 | depends on EISA | |
63 | default y | |
64 | ---help--- | |
65 | By default, the kernel contains a database of all known EISA | |
66 | device names to make the information in sysfs comprehensible | |
67 | to the user. This database increases size of the kernel | |
68 | image by about 40KB, but it gets freed after the system | |
69 | boots up, so it doesn't take up kernel memory. Anyway, if | |
70 | you are building an installation floppy or kernel for an | |
71 | embedded system where kernel image size really matters, you | |
72 | can disable this feature and you'll get device ID instead of | |
73 | names. | |

75 | When in doubt, say Y. |
