1029 Please make sure to pick the right CPU type. Linux/MIPS is not
1030 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1031 *not* work on R4000 machines and vice versa. However, since most
1032 of the supported machines have an R4000 (or similar) CPU, R4x00
1033 might be a safe bet. If the resulting kernel does not work,
1034 try to recompile with R3000.

1924 The Extended Industry Standard Architecture (EISA) bus was
1925 developed as an open alternative to the IBM MicroChannel bus.
1926
1927 The EISA bus provided some of the features of the IBM MicroChannel
1928 bus while maintaining backward compatibility with cards made for
1929 the older ISA bus. The EISA bus saw limited use between 1988 and
1930 1995 when it was made obsolete by the PCI bus.
1931
1932 Say Y here if you are building a kernel for an EISA-based machine.
1933
1934 Otherwise, say N.
