The EISA bus saw limited use between 1988 and 43 1995 when it was made obsolete by the PCI bus. 44 45 Say Y here if you are building a kernel for an EISA-based machine. 46 47 Otherwise, say N. 48 49config MCA 50 bool 51 help 52 MicroChannel Architecture is found in some IBM PS/2 machines and 53 laptops.

These are credit-card size devices such as network cards, 62 modems or hard drives often used with laptops computers. There are 63 actually two varieties of these cards: the older 16 bit PCMCIA cards 64 and the newer 32 bit CardBus cards. If you want to use CardBus 65 cards, you need to say Y here and also to "CardBus support" below. 66 67 To use your PC-cards, you will need supporting software from David 68 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes> 69 for location). Please also read the PCMCIA-HOWTO, available from 70 <http://www.tldp.org/docs.html#howto>. 71 72 To compile this driver as modules, choose M here: the 73 modules will be called pcmcia_core and ds. 74 75config SUN3 76 bool "Sun3 support" 77 select M68020 78 select MMU_SUN3 if MMU 79 help 80 This option enables support for the Sun 3 series of workstations 81 (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires 82 that all other hardware types must be disabled, as Sun 3 kernels 83 are incompatible with all other m68k targets (including Sun 3x!). 84 85 If you don't want to compile a kernel exclusively for a Sun 3, say N. 86 87config AMIGA 88 bool "Amiga support" 89 depends on !MMU_SUN3 90 help 91 This option enables support for the Amiga series of computers.

PCI is the name of a 117 bus system, i.e. the way the CPU talks to the other stuff inside 118 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or 119 VESA. If you have PCI, say Y, otherwise N. 120 121 The PCI-HOWTO, available from 122 <http://www.tldp.org/docs.html#howto>, contains valuable 123 information about which PCI hardware does work under Linux and which 124 doesn't. 125 126config MAC 127 bool "Macintosh support" 128 depends on !MMU_SUN3 129 help 130 This option enables support for the Apple Macintosh series of 131 computers (yes, there is experimental support now, at least for part 132 of the series). 133 134 Say N unless you're willing to code the remaining necessary support. 135 ;) 136 137config NUBUS 138 bool 139 depends on MAC 140 default y 141 142config M68K_L2_CACHE 143 bool 144 depends on MAC 145 default y 146 147config APOLLO 148 bool "Apollo support" 149 depends on !MMU_SUN3 150 help 151 Say Y here if you want to run Linux on an MC680x0-based Apollo 152 Domain workstation such as the DN3500. 153 154config VME 155 bool "VME (Motorola and BVM) support" 156 depends on !MMU_SUN3 157 help 158 Say Y here if you want to build a kernel for a 680x0 based VME 159 board.

Support for these machines is still somewhat 197 experimental. If you plan to try to use the kernel on such a machine 198 say Y here. 199 Everybody else says N. 200 201config DIO 202 bool "DIO bus support" 203 depends on HP300 204 default y 205 help 206 Say Y here to enable support for the "DIO" expansion bus used in 207 HP300 machines.

Otherwise, say N. Note that the 68020 requires a 240 68851 MMU (Memory Management Unit) to run Linux/m68k, except on the 241 Sun 3, which provides its own version. 242 243config M68030 244 bool "68030 support" 245 depends on !MMU_SUN3 246 help 247 If you anticipate running this kernel on a computer with a MC68030 248 processor, say Y. Otherwise, say N. Note that a MC68EC030 will not 249 work, as it does not include an MMU (Memory Management Unit). 250 251config M68040 252 bool "68040 support" 253 depends on !MMU_SUN3 254 help 255 If you anticipate running this kernel on a computer with a MC68LC040 256 or MC68040 processor, say Y. Otherwise, say N.

Thrill-seekers and chronically 282 sleep-deprived psychotic hacker types can say Y now, everyone else 283 should probably wait a while. 284 285config M68KFPU_EMU_EXTRAPREC 286 bool "Math emulation extra precision" 287 depends on M68KFPU_EMU 288 help 289 The fpu uses normally a few bit more during calculations for 290 correct rounding, the emulator can (often) do the same but this 291 extra calculation can cost quite some time, so you can disable 292 it here. The emulator will then "only" calculate with a 64 bit 293 mantissa and round slightly incorrect, what is more then enough 294 for normal usage. 295 296config M68KFPU_EMU_ONLY 297 bool "Math emulation only kernel" 298 depends on M68KFPU_EMU 299 help 300 This option prevents any floating-point instructions from being 301 compiled into the kernel, thereby the kernel doesn't save any 302 floating point context anymore during task switches, so this 303 kernel will only be usable on machines without a floating-point 304 math coprocessor. This makes the kernel a bit faster as no tests 305 needs to be executed whether a floating-point instruction in the 306 kernel should be executed or not. 307 308config ADVANCED 309 bool "Advanced configuration options" 310 ---help--- 311 This gives you access to some advanced options for the CPU. The 312 defaults should be fine for most users, but these options may make 313 it possible for you to improve performance somewhat if you know what 314 you are doing. 315 316 Note that the answer to this question won't directly affect the 317 kernel: saying N will just cause the configurator to skip all 318 the questions about these options. 319 320 Most users should say N to this question. 321 322config RMW_INSNS 323 bool "Use read-modify-write instructions" 324 depends on ADVANCED 325 ---help--- 326 This allows to use certain instructions that work with indivisible 327 read-modify-write bus cycles. While this is faster than the 328 workaround of disabling interrupts, it can conflict with DMA 329 ( = direct memory access) on many Amiga systems, and it is also said 330 to destabilize other machines. It is very likely that this will 331 cause serious problems on any Amiga or Atari Medusa if set. The only 332 configuration where it should work are 68030-based Ataris, where it 333 apparently improves performance. But you've been warned! Unless you 334 really know what you are doing, say N. Try Y only if you're quite 335 adventurous. 336 337config SINGLE_MEMORY_CHUNK 338 bool "Use one physical chunk of memory only" 339 depends on ADVANCED && !SUN3 340 help 341 Ignore all but the first contiguous chunk of physical memory for VM 342 purposes. This will save a few bytes kernel size and may speed up 343 some operations. Say N if not sure. 344 345config 060_WRITETHROUGH 346 bool "Use write-through caching for 68060 supervisor accesses" 347 depends on ADVANCED && M68060 348 ---help--- 349 The 68060 generally uses copyback caching of recently accessed data. 350 Copyback caching means that memory writes will be held in an on-chip 351 cache and only written back to memory some time later. Saying Y 352 here will force supervisor (kernel) accesses to use writethrough 353 caching. Writethrough caching means that data is written to memory 354 straight away, so that cache and memory data always agree. 355 Writethrough caching is less efficient, but is needed for some 356 drivers on 68060 based systems where the 68060 bus snooping signal 357 is hardwired on. The 53c710 SCSI driver is known to suffer from 358 this problem. 359 360endmenu 361 362menu "General setup" 363 364source "fs/Kconfig.binfmt" 365 366config ZORRO 367 bool "Amiga Zorro (AutoConfig) bus support" 368 depends on AMIGA 369 help 370 This enables support for the Zorro bus in the Amiga. If you have 371 expansion cards in your Amiga that conform to the Amiga 372 AutoConfig(tm) specification, say Y, otherwise N. Note that even 373 expansion cards that do not fit in the Zorro slots but fit in e.g. 374 the CPU slot may fall in this category, so you have to say Y to let 375 Linux use these. 376 377config AMIGA_PCMCIA 378 bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)" 379 depends on AMIGA && EXPERIMENTAL 380 help 381 Include support in the kernel for pcmcia on Amiga 1200 and Amiga 382 600. If you intend to use pcmcia cards say Y; otherwise say N. 383 384config STRAM_SWAP 385 bool "Support for ST-RAM as swap space" 386 depends on ATARI && BROKEN 387 ---help--- 388 Some Atari 68k machines (including the 520STF and 1020STE) divide 389 their addressable memory into ST and TT sections. The TT section 390 (up to 512MB) is the main memory; the ST section (up to 4MB) is 391 accessible to the built-in graphics board, runs slower, and is 392 present mainly for backward compatibility with older machines. 393 394 This enables support for using (parts of) ST-RAM as swap space, 395 instead of as normal system memory. This can first enhance system 396 performance if you have lots of alternate RAM (compared to the size 397 of ST-RAM), because executable code always will reside in faster 398 memory. ST-RAM will remain as ultra-fast swap space. On the other 399 hand, it allows much improved dynamic allocations of ST-RAM buffers 400 for device driver modules (e.g. floppy, ACSI, SLM printer, DMA 401 sound). The probability that such allocations at module load time 402 fail is drastically reduced. 403 404config STRAM_PROC 405 bool "ST-RAM statistics in /proc" 406 depends on ATARI 407 help 408 Say Y here to report ST-RAM usage statistics in /proc/stram.

(Try "man bootparam" or see the documentation of 651 your boot loader (lilo or loadlin) about how to pass options to the 652 kernel at boot time.) 653 654 If you don't have a VGA card installed and you say Y here, the 655 kernel will automatically use the first serial line, /dev/ttyS0, as 656 system console. 657 658 If unsure, say N. 659 660endmenu 661 662source "fs/Kconfig" 663 664source "arch/m68k/Kconfig.debug" 665 666source "security/Kconfig" 667 668source "crypto/Kconfig" 669 670source "lib/Kconfig"
