1278 Please make sure to pick the right CPU type. Linux/MIPS is not
1279 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1280 *not* work on R4000 machines and vice versa. However, since most
1281 of the supported machines have an R4000 (or similar) CPU, R4x00
1282 might be a safe bet. If the resulting kernel does not work,
1283 try to recompile with R3000.

1506 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1507 require workarounds. Without workarounds the system may hang
1508 unexpectedly. For more information please refer to the gas
1509 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1510
1511 Loongson 2F03 and later have fixed these issues and no workarounds
1512 are needed. The workarounds have no significant side effect on them
1513 but may decrease the performance of the system so this option should
1514 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1515 systems.

2443 concerning its effect upon the O32 ABI in userland are still being
2444 worked on. In order to avoid userland becoming dependant upon current
2445 behaviour before the details have been finalised, this option should
2446 be considered experimental and only enabled by those working upon
2447 said details.

2521 The Extended Industry Standard Architecture (EISA) bus was
2522 developed as an open alternative to the IBM MicroChannel bus.
2523
2524 The EISA bus provided some of the features of the IBM MicroChannel
2525 bus while maintaining backward compatibility with cards made for
2526 the older ISA bus. The EISA bus saw limited use between 1988 and
2527 1995 when it was made obsolete by the PCI bus.
