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