|  | Find out whether you have ISA slots on your motherboard.  ISA is the | 
|  | name of a bus system, i.e. the way the CPU talks to the other stuff | 
|  | inside your box.  Other bus systems are PCI, EISA, MicroChannel | 
|  | (MCA) or VESA.  ISA is an older system, now being displaced by PCI; | 
|  | newer boards don't support it.  If you have ISA, say Y, otherwise N. |

|  | The Extended Industry Standard Architecture (EISA) bus was |

|  | The EISA bus provided some of the features of the IBM MicroChannel | 
|  | bus while maintaining backward compatibility with cards made for |

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