1043 Please make sure to pick the right CPU type. Linux/MIPS is not
1044 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1045 *not* work on R4000 machines and vice versa. However, since most
1046 of the supported machines have an R4000 (or similar) CPU, R4x00
1047 might be a safe bet. If the resulting kernel does not work,
1048 try to recompile with R3000.

1956 The EISA bus provided some of the features of the IBM MicroChannel
1957 bus while maintaining backward compatibility with cards made for
1958 the older ISA bus. The EISA bus saw limited use between 1988 and
1959 1995 when it was made obsolete by the PCI bus.

1961 Say Y here if you are building a kernel for an EISA-based machine.

1963 Otherwise, say N.
