1230 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1231 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1232 | *not* work on R4000 machines and vice versa. However, since most | |
1233 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1234 | might be a safe bet. If the resulting kernel does not work, | |
1235 | try to recompile with R3000. | |

2412 | The Extended Industry Standard Architecture (EISA) bus was | |
2413 | developed as an open alternative to the IBM MicroChannel bus. | |
2414 | ||
2415 | The EISA bus provided some of the features of the IBM MicroChannel | |
2416 | bus while maintaining backward compatibility with cards made for | |
2417 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2418 | 1995 when it was made obsolete by the PCI bus. | |
2419 | ||
2420 | Say Y here if you are building a kernel for an EISA-based machine. | |
2421 | ||
2422 | Otherwise, say N. | |
