| 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. |

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

| help |
| Activate this option if your system contains a PCI to EISA |
| bridge. If your system have both PCI and EISA slots, you |
| certainly need this option. |
| |
| When in doubt, say Y. |

| help |
| Activate this option if your system only have EISA bus |
| (no PCI slots). The Alpha Jensen is an example of such |
| a system. |
| |
| When in doubt, say Y. |

| By default, the kernel contains a database of all known EISA |
| device names to make the information in sysfs comprehensible |
| to the user. This database increases size of the kernel |
| image by about 40KB, but it gets freed after the system |
| boots up, so it doesn't take up kernel memory. Anyway, if |
| you are building an installation floppy or kernel for an |
| embedded system where kernel image size really matters, you |
| can disable this feature and you'll get device ID instead of |
| names. |
| |
| When in doubt, say Y. |
