1259 Please make sure to pick the right CPU type. Linux/MIPS is not
1260 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1261 *not* work on R4000 machines and vice versa. However, since most
1262 of the supported machines have an R4000 (or similar) CPU, R4x00
1263 might be a safe bet. If the resulting kernel does not work,
1264 try to recompile with R3000.

1468 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1469 require workarounds. Without workarounds the system may hang
1470 unexpectedly. For more information please refer to the gas
1471 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1472
1473 Loongson 2F03 and later have fixed these issues and no workarounds
1474 are needed. The workarounds have no significant side effect on them
1475 but may decrease the performance of the system so this option should
1476 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1477 systems.
1478
1479 If unsure, please say Y.

1799 This config option is actually maximum order plus one. For example,
1800 a value of 11 means that the largest free memory block is 2^10 pages.

2466 The Extended Industry Standard Architecture (EISA) bus was
2467 developed as an open alternative to the IBM MicroChannel bus.
2468
2469 The EISA bus provided some of the features of the IBM MicroChannel
2470 bus while maintaining backward compatibility with cards made for
2471 the older ISA bus. The EISA bus saw limited use between 1988 and
2472 1995 when it was made obsolete by the PCI bus.
2473
2474 Say Y here if you are building a kernel for an EISA-based machine.
2475
2476 Otherwise, say N.
