1223 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1224 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1225 | *not* work on R4000 machines and vice versa. However, since most | |
1226 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1227 | might be a safe bet. If the resulting kernel does not work, | |
1228 | try to recompile with R3000. | |

2053 | This enables support for systems with more than one CPU. If you have |
2054 | a system with only one CPU, like most personal computers, say N. If | |
2055 | you have a system with more than one CPU, say Y. | |
2056 | ||
2057 | If you say N here, the kernel will run on single and multiprocessor | |
2058 | machines, but will use only one CPU of a multiprocessor machine. If | |
2059 | you say Y here, the kernel will run on many, but not all, | |
2060 | singleprocessor machines. On a singleprocessor machine, the kernel | |
2061 | will run faster if you say N here. | |
2062 | ||
2063 | People using multiprocessor machines who say Y here should also say | |
2064 | Y to "Enhanced Real Time Clock Support", below. | |
