Details about the Linux/Alpha booting process are contained in the Linux/Alpha FAQ, accessible on the WWW from <http://www.alphalinux.org/>. The usual way to load Linux on an Alpha machine is to use MILO (a bootloader that lets you pass command line parameters to the kernel just like lilo does for the x86 architecture) which can be loaded either from ARC or can be installed directly as a permanent firmware replacement from floppy (which requires changing a certain jumper on the motherboard). If you want to do either of these, say N here. If MILO doesn't work on your system (true for Jensen motherboards), you can bypass it altogether and boot Linux directly from an SRM console; say Y here in order to do that. Note that you won't be able to boot from an IDE disk using SRM. If unsure, say N. config EISA bool depends on ALPHA_GENERIC || ALPHA_JENSEN || ALPHA_ALCOR || ALPHA_MIKASA || ALPHA_SABLE || ALPHA_LYNX || ALPHA_NORITAKE || ALPHA_RAWHIDE default y config ARCH_MAY_HAVE_PC_FDC def_bool y config SMP bool "Symmetric multi-processing support" depends on ALPHA_SABLE || ALPHA_LYNX || ALPHA_RAWHIDE || ALPHA_DP264 || ALPHA_WILDFIRE || ALPHA_TITAN || ALPHA_GENERIC || ALPHA_SHARK || ALPHA_MARVEL select USE_GENERIC_SMP_HELPERS ---help--- This enables support for systems with more than one CPU. If you have a system with only one CPU, like most personal computers, say N. If you have a system with more than one CPU, say Y. If you say N here, the kernel will run on single and multiprocessor machines, but will use only one CPU of a multiprocessor machine. If you say Y here, the kernel will run on many, but not all, singleprocessor machines. On a singleprocessor machine, the kernel will run faster if you say N here. See also the SMP-HOWTO available at <http://www.tldp.org/docs.html#howto>. If you don't know what to do here, say N. config HAVE_DEC_LOCK bool depends on SMP default y config NR_CPUS int "Maximum number of CPUs (2-32)" range 2 32 depends on SMP default "32" if ALPHA_GENERIC || ALPHA_MARVEL default "4" if !ALPHA_GENERIC && !ALPHA_MARVEL help MARVEL support can handle a maximum of 32 CPUs, all the others with working support have a maximum of 4 CPUs. config ARCH_DISCONTIGMEM_ENABLE bool "Discontiguous Memory Support (EXPERIMENTAL)" depends on EXPERIMENTAL help Say Y to support efficient handling of discontiguous physical memory, for architectures which are either NUMA (Non-Uniform Memory Access) or have huge holes in the physical address space for other reasons. See <file:Documentation/vm/numa> for more. source "mm/Kconfig" config NUMA bool "NUMA Support (EXPERIMENTAL)" depends on DISCONTIGMEM && BROKEN help Say Y to compile the kernel to support NUMA (Non-Uniform Memory Access). This option is for configuring high-end multiprocessor server machines. If in doubt, say N. config NODES_SHIFT int default "7" depends on NEED_MULTIPLE_NODES # LARGE_VMALLOC is racy, if you *really* need it then fix it first config ALPHA_LARGE_VMALLOC bool ---help--- Process creation and other aspects of virtual memory management can be streamlined if we restrict the kernel to one PGD for all vmalloc allocations. This equates to about 8GB. Under normal circumstances, this is so far and above what is needed as to be laughable. However, there are certain applications (such as benchmark-grade in-kernel web serving) that can make use of as much vmalloc space as is available. Say N unless you know you need gobs and gobs of vmalloc space. config VERBOSE_MCHECK bool "Verbose Machine Checks" config VERBOSE_MCHECK_ON int "Verbose Printing Mode (0=off, 1=on, 2=all)" depends on VERBOSE_MCHECK default 1 ---help--- This option allows the default printing mode to be set, and then possibly overridden by a boot command argument. For example, if one wanted the option of printing verbose machine checks, but wanted the default to be as if verbose machine check printing was turned off, then one would choose the printing mode to be 0. Then, upon reboot, one could add the boot command line "verbose_mcheck=1" to get the normal verbose machine check printing, or "verbose_mcheck=2" to get the maximum information available. Take the default (1) unless you want more control or more info. config HZ int default 1200 if ALPHA_RAWHIDE default 1024 source "drivers/pci/Kconfig" source "drivers/eisa/Kconfig" source "drivers/pcmcia/Kconfig" config SRM_ENV tristate "SRM environment through procfs" depends on PROC_FS ---help--- If you enable this option, a subdirectory inside /proc called /proc/srm_environment will give you access to the all important SRM environment variables (those which have a name) and also to all others (by their internal number). SRM is something like a BIOS for Alpha machines. There are some other such BIOSes, like AlphaBIOS, which this driver cannot support (hey, that's not SRM!). Despite the fact that this driver doesn't work on all Alphas (but only on those which have SRM as their firmware), it's save to build it even if your particular machine doesn't know about SRM (or if you intend to compile a generic kernel). It will simply not create those subdirectory in /proc (and give you some warning, of course). This driver is also available as a module and will be called srm_env then. source "fs/Kconfig.binfmt" endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "arch/alpha/Kconfig.debug" # DUMMY_CONSOLE may be defined in drivers/video/console/Kconfig # but we also need it if VGA_HOSE is set config DUMMY_CONSOLE bool depends on VGA_HOSE default y source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
