| 13 | The Extended Industry Standard Architecture (EISA) bus was |
| 14 | developed as an open alternative to the IBM MicroChannel bus. |
| 15 | |
| 16 | The EISA bus provided some of the features of the IBM MicroChannel |
| 17 | bus while maintaining backward compatibility with cards made for |
| 18 | the older ISA bus. The EISA bus saw limited use between 1988 and |
| 19 | 1995 when it was made obsolete by the PCI bus. |
| 20 | |
| 21 | Say Y here if you are building a kernel for an EISA-based machine. |
| 22 | |
| 23 | Otherwise, say N. |

| 65 | ---help--- |
| 66 | By default, the kernel contains a database of all known EISA |
| 67 | device names to make the information in sysfs comprehensible |
| 68 | to the user. This database increases size of the kernel |
| 69 | image by about 40KB, but it gets freed after the system |
| 70 | boots up, so it doesn't take up kernel memory. Anyway, if |
| 71 | you are building an installation floppy or kernel for an |
| 72 | embedded system where kernel image size really matters, you |
| 73 | can disable this feature and you'll get device ID instead of |
| 74 | names. |

| 76 | When in doubt, say Y. |
