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.
98 # Compressed boot loader in ROM. Yes, we really want to ask about
99 # TEXT and BSS so we preserve their values in the config files.
101 bool "Compressed boot loader in ROM/flash"
103 Say Y here if you intend to execute your compressed kernel image (zImage)
104 directly from ROM or flash. If unsure, say N.
106 config ZBOOT_ROM_TEXT
108 hex "Compressed ROM boot loader base address"
111 The base address for zImage. Unless you have special requirements, you
112 should not change this value.
116 hex "Compressed ROM boot loader BSS address"
119 The base address of 64KiB of read/write memory, which must be available
120 while the decompressor is running. Unless you have special requirements,
121 you should not change this value.
124 bool "Execute In Place (XIP) kernel image"
126 Select this option to create a kernel that can be programed into
129 comment "At least one math emulation must be selected"
132 tristate "NWFPE math emulation"
134 Say Y to include the NWFPE floating point emulator in the kernel.
135 This is necessary to run most binaries. Linux does not currently
136 support floating point hardware so you need to say Y here even if
137 your machine has an FPA or floating point co-processor podule.
139 It is also possible to say M to build the emulator as a module
140 (nwfpe) or indeed to leave it out altogether. However, unless you
141 know what you are doing this can easily render your machine
142 unbootable. Saying Y is the safe option.
144 You may say N here if you are going to load the Acorn FPEmulator
147 source "fs/Kconfig.binfmt"
150 bool "Preemptible Kernel (EXPERIMENTAL)"
151 depends on CPU_32 && EXPERIMENTAL
153 This option reduces the latency of the kernel when reacting to
154 real-time or interactive events by allowing a low priority process to
155 be preempted even if it is in kernel mode executing a system call.
156 This allows applications to run more reliably even when the system is
159 Say Y here if you are building a kernel for a desktop, embedded
160 or real-time system. Say N if you are unsure.
163 tristate "RISC OS personality"
166 Say Y here to include the kernel code necessary if you want to run
167 Acorn RISC OS/Arthur binaries under Linux. This code is still very
168 experimental; if this sounds frightening, say N and sleep in peace.
169 You can also say M here to compile this support as a module (which
170 will be called arthur).
173 string "Default kernel command string"
176 On some architectures (EBSA110 and CATS), there is currently no way
177 for the boot loader to pass arguments to the kernel. For these
178 architectures, you should supply some command-line options at build
179 time by entering them here. As a minimum, you should specify the
180 memory size and the root device (e.g., mem=64M root=/dev/nfs).
