1549 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1550 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1551 | *not* work on R4000 machines and vice versa. However, since most | |
1552 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1553 | might be a safe bet. If the resulting kernel does not work, | |
1554 | try to recompile with R3000. | |
