1264 Please make sure to pick the right CPU type. Linux/MIPS is not
1265 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1266 *not* work on R4000 machines and vice versa. However, since most
1267 of the supported machines have an R4000 (or similar) CPU, R4x00
1268 might be a safe bet. If the resulting kernel does not work,
1269 try to recompile with R3000.

1829 Virtual SMP uses the processor's VPEs to implement virtual
1830 processors. In currently available configuration of the 34K processor
1831 this allows for a dual processor. Both processors will share the same
1832 primary caches; each will obtain the half of the TLB for it's own
1833 exclusive use. For a layman this model can be described as similar to
1834 what Intel calls Hyperthreading.

2276 This kernel feature is useful for number crunching applications
2277 that may need to compute untrusted bytecode during their
2278 execution. By using pipes or other transports made available to
2279 the process as file descriptors supporting the read/write
2280 syscalls, it's possible to isolate those applications in
2281 their own address space using seccomp. Once seccomp is
2282 enabled via /proc/<pid>/seccomp, it cannot be disabled
2283 and the task is only allowed to execute a few safe syscalls
2284 defined by each seccomp mode.
2285
2286 If unsure, say Y. Only embedded should say N here.

2345 The Extended Industry Standard Architecture (EISA) bus was
2346 developed as an open alternative to the IBM MicroChannel bus.
2347
2348 The EISA bus provided some of the features of the IBM MicroChannel
2349 bus while maintaining backward compatibility with cards made for
2350 the older ISA bus. The EISA bus saw limited use between 1988 and
2351 1995 when it was made obsolete by the PCI bus.
