76 prompt "Archimedes/A5000 Implementations"
81 Say Y to support the Acorn Archimedes.
83 The Acorn Archimedes was an personal computer based on an 8MHz ARM2
84 processor, released in 1987. It supported up to 16MB of RAM in
85 later models and floppy, harddisc, ethernet etc.
89 select ARCH_MAY_HAVE_PC_FDC
91 Say Y here to support the Acorn A5000.
94 internal IDE disk and CD-ROM interface, serial and parallel port,
95 and the floppy drive. Note that on some A5000s the floppy is
96 plugged into the wrong socket on the motherboard.
99 bool "2MB physical memory (broken)"
101 Say Y here if your Archimedes or A5000 system has only 2MB of
102 memory, otherwise say N. The resulting kernel will not run on a
103 machine with 4MB of memory.
113 # Compressed boot loader in ROM. Yes, we really want to ask about
114 # TEXT and BSS so we preserve their values in the config files.
116 bool "Compressed boot loader in ROM/flash"
118 Say Y here if you intend to execute your compressed kernel image (zImage)
119 directly from ROM or flash. If unsure, say N.
121 config ZBOOT_ROM_TEXT
123 hex "Compressed ROM boot loader base address"
126 The base address for zImage. Unless you have special requirements, you
127 should not change this value.
131 hex "Compressed ROM boot loader BSS address"
134 The base address of 64KiB of read/write memory, which must be available
135 while the decompressor is running. Unless you have special requirements,
136 you should not change this value.
139 bool "Execute In Place (XIP) kernel image"
141 Select this option to create a kernel that can be programmed into
144 comment "At least one math emulation must be selected"
147 tristate "NWFPE math emulation"
149 Say Y to include the NWFPE floating point emulator in the kernel.
150 This is necessary to run most binaries. Linux does not currently
151 support floating point hardware so you need to say Y here even if
152 your machine has an FPA or floating point co-processor module.
154 It is also possible to say M to build the emulator as a module
155 (nwfpe) or indeed to leave it out altogether. However, unless you
156 know what you are doing this can easily render your machine
157 unbootable. Saying Y is the safe option.
159 You may say N here if you are going to load the Acorn FPEmulator
162 source "fs/Kconfig.binfmt"
165 bool "Preemptible Kernel (EXPERIMENTAL)"
166 depends on CPU_32 && EXPERIMENTAL
168 This option reduces the latency of the kernel when reacting to
169 real-time or interactive events by allowing a low priority process to
170 be preempted even if it is in kernel mode executing a system call.
171 This allows applications to run more reliably even when the system is
174 Say Y here if you are building a kernel for a desktop, embedded
175 or real-time system. Say N if you are unsure.
178 tristate "RISC OS personality"
181 Say Y here to include the kernel code necessary if you want to run
182 Acorn RISC OS/Arthur binaries under Linux. This code is still very
183 experimental; if this sounds frightening, say N and sleep in peace.
184 You can also say M here to compile this support as a module (which
185 will be called arthur).
188 string "Default kernel command string"
191 On some architectures (EBSA110 and CATS), there is currently no way
192 for the boot loader to pass arguments to the kernel. For these
193 architectures, you should supply some command-line options at build
194 time by entering them here. As a minimum, you should specify the
195 memory size and the root device (e.g., mem=64M root=/dev/nfs).
