1216 Please make sure to pick the right CPU type. Linux/MIPS is not
1217 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1218 *not* work on R4000 machines and vice versa. However, since most
1219 of the supported machines have an R4000 (or similar) CPU, R4x00
1220 might be a safe bet. If the resulting kernel does not work,
1221 try to recompile with R3000.

1769 Virtual SMP uses the processor's VPEs to implement virtual
1770 processors. In currently available configuration of the 34K processor
1771 this allows for a dual processor. Both processors will share the same
1772 primary caches; each will obtain the half of the TLB for it's own
1773 exclusive use. For a layman this model can be described as similar to
1774 what Intel calls Hyperthreading.

1924 SmartMIPS is a extension of the MIPS32 architecture aimed at
1925 increased security at both hardware and software level for
1926 smartcards. Enabling this option will allow proper use of the
1927 SmartMIPS instructions by Linux applications. However a kernel with
1928 this option will not work on a MIPS core without SmartMIPS core. If
1929 you don't know you probably don't have SmartMIPS and should say N

2295 The Extended Industry Standard Architecture (EISA) bus was
2296 developed as an open alternative to the IBM MicroChannel bus.
2297
2298 The EISA bus provided some of the features of the IBM MicroChannel
2299 bus while maintaining backward compatibility with cards made for
2300 the older ISA bus. The EISA bus saw limited use between 1988 and
2301 1995 when it was made obsolete by the PCI bus.
2302
2303 Say Y here if you are building a kernel for an EISA-based machine.
2304
2305 Otherwise, say N.
