1059 Please make sure to pick the right CPU type. Linux/MIPS is not
1060 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1061 *not* work on R4000 machines and vice versa. However, since most
1062 of the supported machines have an R4000 (or similar) CPU, R4x00
1063 might be a safe bet. If the resulting kernel does not work,
1064 try to recompile with R3000.

1586 SmartMIPS is a extension of the MIPS32 architecture aimed at
1587 increased security at both hardware and software level for
1588 smartcards. Enabling this option will allow proper use of the
1589 SmartMIPS instructions by Linux applications. However a kernel with
1590 this option will not work on a MIPS core without SmartMIPS core. If
1591 you don't know you probably don't have SmartMIPS and should say N

1969 The Extended Industry Standard Architecture (EISA) bus was
1970 developed as an open alternative to the IBM MicroChannel bus.
1971
1972 The EISA bus provided some of the features of the IBM MicroChannel
1973 bus while maintaining backward compatibility with cards made for
1974 the older ISA bus. The EISA bus saw limited use between 1988 and
1975 1995 when it was made obsolete by the PCI bus.
1976
1977 Say Y here if you are building a kernel for an EISA-based machine.
1978
1979 Otherwise, say N.
