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. |

default y |
|
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. |

# Using EISA_VIRTUAL_ROOT on something other than an Alpha or |

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. |

help |
|
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.
