1028 Please make sure to pick the right CPU type. Linux/MIPS is not
1029 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1030 *not* work on R4000 machines and vice versa. However, since most
1031 of the supported machines have an R4000 (or similar) CPU, R4x00
1032 might be a safe bet. If the resulting kernel does not work,
1033 try to recompile with R3000.

1923 The Extended Industry Standard Architecture (EISA) bus was
1924 developed as an open alternative to the IBM MicroChannel bus.
1925
1926 The EISA bus provided some of the features of the IBM MicroChannel
1927 bus while maintaining backward compatibility with cards made for
1928 the older ISA bus. The EISA bus saw limited use between 1988 and
1929 1995 when it was made obsolete by the PCI bus.
1930
1931 Say Y here if you are building a kernel for an EISA-based machine.
1932
1933 Otherwise, say N.

1942 processors. Documentation on writing device drivers for TurboChannel
