80 Say Y to support the Acorn Archimedes.
81
82 The Acorn Archimedes was an personal computer based on an 8MHz ARM2
83 processor, released in 1987. It supported up to 16MB of RAM in
84 later models and floppy, harddisc, ethernet etc.

91
92 Linux can support the
93 internal IDE disk and CD-ROM interface, serial and parallel port,
94 and the floppy drive. Note that on some A5000s the floppy is
95 plugged into the wrong socket on the motherboard.

102 machine with 4MB of memory.

145config FPE_NWFPE
146 tristate "NWFPE math emulation"
147 ---help---
148 Say Y to include the NWFPE floating point emulator in the kernel.
149 This is necessary to run most binaries. Linux does not currently
150 support floating point hardware so you need to say Y here even if
151 your machine has an FPA or floating point co-processor module.
152
153 It is also possible to say M to build the emulator as a module
154 (nwfpe) or indeed to leave it out altogether. However, unless you
155 know what you are doing this can easily render your machine
156 unbootable. Saying Y is the safe option.
157
158 You may say N here if you are going to load the Acorn FPEmulator
159 early in the bootup.

166 help
167 This option reduces the latency of the kernel when reacting to
168 real-time or interactive events by allowing a low priority process to
169 be preempted even if it is in kernel mode executing a system call.
170 This allows applications to run more reliably even when the system is
171 under load.
172
173 Say Y here if you are building a kernel for a desktop, embedded
174 or real-time system. Say N if you are unsure.

179 help
180 Say Y here to include the kernel code necessary if you want to run
181 Acorn RISC OS/Arthur binaries under Linux. This code is still very
182 experimental; if this sounds frightening, say N and sleep in peace.
183 You can also say M here to compile this support as a module (which
184 will be called arthur).

189 help
190 On some architectures (EBSA110 and CATS), there is currently no way
191 for the boot loader to pass arguments to the kernel. For these
192 architectures, you should supply some command-line options at build
193 time by entering them here. As a minimum, you should specify the
194 memory size and the root device (e.g., mem=64M root=/dev/nfs).
