  59. Say Y to support the Acorn Archimedes.
  60. The Acorn Archimedes was an personal computer based on an 8MHz ARM2
  61. processor, released in 1987. It supported up to 16MB of RAM in
  62. later models and floppy, harddisc, ethernet etc.

  67. Say Y here to support the Acorn A5000.
  68. Linux can support the
  69. internal IDE disk and CD-ROM interface, serial and parallel port,
  70. and the floppy drive. Note that on some A5000s the floppy is
  71. plugged into the wrong socket on the motherboard.
  72. config PAGESIZE_16

  74. help
  75. Say Y here if your Archimedes or A5000 system has only 2MB of
  76. memory, otherwise say N. The resulting kernel will not run on a
  77. machine with 4MB of memory.

  114. ---help---
  115. Say Y to include the NWFPE floating point emulator in the kernel.
  116. This is necessary to run most binaries. Linux does not currently
  117. support floating point hardware so you need to say Y here even if
  118. your machine has an FPA or floating point co-processor module.
  119. It is also possible to say M to build the emulator as a module
  120. (nwfpe) or indeed to leave it out altogether. However, unless you
  121. know what you are doing this can easily render your machine
  122. unbootable. Saying Y is the safe option.
  123. You may say N here if you are going to load the Acorn FPEmulator
  124. early in the bootup.

  128. depends on CPU_32 && EXPERIMENTAL
  129. help
  130. This option reduces the latency of the kernel when reacting to
  131. real-time or interactive events by allowing a low priority process to
  132. be preempted even if it is in kernel mode executing a system call.
  133. This allows applications to run more reliably even when the system is
  134. under load.
  135. Say Y here if you are building a kernel for a desktop, embedded
  136. or real-time system. Say N if you are unsure.
  137. config ARTHUR

  139. depends on CPU_32
  140. help
  141. Say Y here to include the kernel code necessary if you want to run
  142. Acorn RISC OS/Arthur binaries under Linux. This code is still very
  143. experimental; if this sounds frightening, say N and sleep in peace.
  144. You can also say M here to compile this support as a module (which
  145. will be called arthur).
  146. config CMDLINE
  147. string "Default kernel command string"
  148. default ""
  149. help
  150. On some architectures (EBSA110 and CATS), there is currently no way
  151. for the boot loader to pass arguments to the kernel. For these
  152. architectures, you should supply some command-line options at build
  153. time by entering them here. As a minimum, you should specify the
  154. memory size and the root device (e.g., mem=64M root=/dev/nfs).
