1262 Please make sure to pick the right CPU type. Linux/MIPS is not
1263 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1264 *not* work on R4000 machines and vice versa. However, since most
1265 of the supported machines have an R4000 (or similar) CPU, R4x00
1266 might be a safe bet. If the resulting kernel does not work,
1267 try to recompile with R3000.

1491 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1492 require workarounds. Without workarounds the system may hang
1493 unexpectedly. For more information please refer to the gas
1494 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1495
1496 Loongson 2F03 and later have fixed these issues and no workarounds
1497 are needed. The workarounds have no significant side effect on them
1498 but may decrease the performance of the system so this option should
1499 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1500 systems.

1829 a value of 11 means that the largest free memory block is 2^10 pages.

2450 32-bit MIPS systems this support is at the cost of increasing the
2451 size and complexity of the compiled FPU emulator. Thus if you are
2452 running a MIPS32 system and know that none of your userland binaries
2453 will require 64-bit floating point, you may wish to reduce the size
2454 of your kernel & potentially improve FP emulation performance by
2455 saying N here.
2456
2457 If unsure, say Y.

2518 The Extended Industry Standard Architecture (EISA) bus was
2519 developed as an open alternative to the IBM MicroChannel bus.
2520
2521 The EISA bus provided some of the features of the IBM MicroChannel
2522 bus while maintaining backward compatibility with cards made for
2523 the older ISA bus. The EISA bus saw limited use between 1988 and
2524 1995 when it was made obsolete by the PCI bus.
