68 Say Y to support the Acorn Archimedes.
69
70 The Acorn Archimedes was an personal computer based on an 8MHz ARM2
71 processor, released in 1987. It supported up to 16MB of RAM in
72 later models and floppy, harddisc, ethernet etc.

77 Say Y here to to support the Acorn A5000.

79 Linux can support the
80 internal IDE disk and CD-ROM interface, serial and parallel port,
81 and the floppy drive. Note that on some A5000s the floppy is
82 plugged into the wrong socket on the motherboard.

87 Say Y here if your Archimedes or A5000 system has only 2MB of
88 memory, otherwise say N. The resulting kernel will not run on a
89 machine with 4MB of memory.

127config FPE_NWFPE
128 tristate "NWFPE math emulation"
129 ---help---
130 Say Y to include the NWFPE floating point emulator in the kernel.
131 This is necessary to run most binaries. Linux does not currently
132 support floating point hardware so you need to say Y here even if
133 your machine has an FPA or floating point co-processor podule.
134
135 It is also possible to say M to build the emulator as a module
136 (nwfpe) or indeed to leave it out altogether. However, unless you
137 know what you are doing this can easily render your machine
138 unbootable. Saying Y is the safe option.
139
140 You may say N here if you are going to load the Acorn FPEmulator
141 early in the bootup.

145config PREEMPT
146 bool "Preemptible Kernel (EXPERIMENTAL)"
147 depends on CPU_32 && EXPERIMENTAL
148 help
149 This option reduces the latency of the kernel when reacting to
150 real-time or interactive events by allowing a low priority process to
151 be preempted even if it is in kernel mode executing a system call.
152 This allows applications to run more reliably even when the system is
153 under load.
154
155 Say Y here if you are building a kernel for a desktop, embedded
156 or real-time system. Say N if you are unsure.
157
158config ARTHUR
159 tristate "RISC OS personality"
160 depends on CPU_32
161 help
162 Say Y here to include the kernel code necessary if you want to run
163 Acorn RISC OS/Arthur binaries under Linux. This code is still very
164 experimental; if this sounds frightening, say N and sleep in peace.
165 You can also say M here to compile this support as a module (which
166 will be called arthur).

168config CMDLINE
169 string "Default kernel command string"
170 default ""
171 help
172 On some architectures (EBSA110 and CATS), there is currently no way
173 for the boot loader to pass arguments to the kernel. For these
174 architectures, you should supply some command-line options at build
175 time by entering them here. As a minimum, you should specify the
176 memory size and the root device (e.g., mem=64M root=/dev/nfs).
