1270 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1271 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1272 | *not* work on R4000 machines and vice versa. However, since most | |

1274 | might be a safe bet. If the resulting kernel does not work, | |
1275 | try to recompile with R3000. | |

2429 | The Extended Industry Standard Architecture (EISA) bus was | |
2430 | developed as an open alternative to the IBM MicroChannel bus. | |
2431 | ||
2432 | The EISA bus provided some of the features of the IBM MicroChannel | |
2433 | bus while maintaining backward compatibility with cards made for | |
2434 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2435 | 1995 when it was made obsolete by the PCI bus. | |
2436 | ||
2437 | Say Y here if you are building a kernel for an EISA-based machine. | |
2438 | ||
2439 | Otherwise, say N. | |
