63 comment "Archimedes/A5000 Implementations (select only ONE)"
68 Say Y to support the Acorn Archimedes.
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.
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.
85 bool "2MB physical memory (broken)"
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.
94 # Compressed boot loader in ROM. Yes, we really want to ask about
95 # TEXT and BSS so we preserve their values in the config files.
97 bool "Compressed boot loader in ROM/flash"
99 Say Y here if you intend to execute your compressed kernel image (zImage)
100 directly from ROM or flash. If unsure, say N.
102 config ZBOOT_ROM_TEXT
104 hex "Compressed ROM boot loader base address"
107 The base address for zImage. Unless you have special requirements, you
108 should not change this value.
112 hex "Compressed ROM boot loader BSS address"
115 The base address of 64KiB of read/write memory, which must be available
116 while the decompressor is running. Unless you have special requirements,
117 you should not change this value.
120 bool "Execute In Place (XIP) kernel image"
122 Select this option to create a kernel that can be programed into
125 comment "At least one math emulation must be selected"
128 tristate "NWFPE math emulation"
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.
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.
140 You may say N here if you are going to load the Acorn FPEmulator
143 source "fs/Kconfig.binfmt"
146 bool "Preemptible Kernel (EXPERIMENTAL)"
147 depends on CPU_32 && EXPERIMENTAL
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
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.
159 tristate "RISC OS personality"
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).
169 string "Default kernel command string"
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).
