1100 Please make sure to pick the right CPU type. Linux/MIPS is not
1101 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1102 *not* work on R4000 machines and vice versa. However, since most
1103 of the supported machines have an R4000 (or similar) CPU, R4x00
1104 might be a safe bet. If the resulting kernel does not work,
1105 try to recompile with R3000.

1946 It is an ongoing process to be certain the hardware in a machine
1947 is properly shutdown, so do not be surprised if this code does not
1948 initially work for you. It may help to enable device hotplugging
1949 support. As of this writing the exact hardware interface is
1950 strongly in flux, so no good recommendation can be made.

1957 This kernel feature is useful for number crunching applications
1958 that may need to compute untrusted bytecode during their
1959 execution. By using pipes or other transports made available to
1960 the process as file descriptors supporting the read/write
1961 syscalls, it's possible to isolate those applications in
1962 their own address space using seccomp. Once seccomp is
1963 enabled via /proc/<pid>/seccomp, it cannot be disabled
1964 and the task is only allowed to execute a few safe syscalls
1965 defined by each seccomp mode.

1967 If unsure, say Y. Only embedded should say N here.

2032 The Extended Industry Standard Architecture (EISA) bus was
2033 developed as an open alternative to the IBM MicroChannel bus.

2035 The EISA bus provided some of the features of the IBM MicroChannel
2036 bus while maintaining backward compatibility with cards made for
2037 the older ISA bus. The EISA bus saw limited use between 1988 and
2038 1995 when it was made obsolete by the PCI bus.
