It represents the frame buffer of some video hardware and allows application software to access the graphics hardware through a well-defined interface, so the software doesn't need to know anything about the low-level (hardware register) stuff. Frame buffer devices work identically across the different architectures supported by Linux and make the implementation of application programs easier and more portable; at this point, an X server exists which uses the frame buffer device exclusively. On several non-X86 architectures, the frame buffer device is the only way to use the graphics hardware. The device is accessed through special device nodes, usually located in the /dev directory, i.e. /dev/fb*. You need an utility program called fbset to make full use of frame buffer devices. Please read and the Framebuffer-HOWTO at for more information. Say Y here and to the driver for your graphics board below if you are compiling a kernel for a non-x86 architecture.

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. People using multiprocessor machines who say Y here should also say Y to "Enhanced Real Time Clock Support", below. See also the , and the SMP-HOWTO available at .

The maximum supported value is 32 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image. config PREEMPT bool "Preemptible Kernel" help This option reduces the latency of the kernel when reacting to real-time or interactive events by allowing a low priority process to be preempted even if it is in kernel mode executing a system call. This allows applications to run more reliably even when the system is under load. config DEBUG_SPINLOCK_SLEEP bool "Sleep-inside-spinlock checking" help If you say Y here, various routines which may sleep will become very noisy if they are called with a spinlock held. config RTC_DS1742 bool "DS1742 BRAM/RTC support" depends on TOSHIBA_JMR3927 || TOSHIBA_RBTX4927 config MIPS_INSANE_LARGE bool "Support for large 64-bit configurations" depends on CPU_R10000 && MIPS64 help MIPS R10000 does support a 44 bit / 16TB address space as opposed to previous 64-bit processors which only supported 40 bit / 1TB.

In many cases, the devices can likewise be unplugged at any time too. One well known example of this is PCMCIA- or PC-cards, credit-card size devices such as network cards, modems or hard drives which are plugged into slots found on all modern laptop computers. Another example, used on modern desktops as well as laptops, is USB. Enable HOTPLUG and KMOD, and build a modular kernel. Get agent software (at ) and install it. Then your kernel will automatically call out to a user mode "policy agent" (/sbin/hotplug) to load modules and set up software needed to use devices as you hotplug them. source "drivers/pcmcia/Kconfig" source "drivers/pci/hotplug/Kconfig" endmenu menu "Executable file formats" source "fs/Kconfig.binfmt" config TRAD_SIGNALS bool default y if MIPS32 config BINFMT_IRIX bool "Include IRIX binary compatibility" depends on !CPU_LITTLE_ENDIAN && MIPS32 config MIPS32_COMPAT bool "Kernel support for Linux/MIPS 32-bit binary compatibility" depends on MIPS64 help Select this option if you want Linux/MIPS 32-bit binary compatibility.

Be sure to have all the information about your sound card and its configuration down (I/O port, interrupt and DMA channel), because you will be asked for it. You want to read the Sound-HOWTO, available from . General information about the modular sound system is contained in the files . The file contains some slightly outdated but still useful information as well. If you have a PnP sound card and you want to configure it at boot time using the ISA PnP tools (read ), then you need to compile the sound card support as a module and load that module after the PnP configuration is finished. To do this, choose M here and read ; the module will be called soundcore.

This is accomplished by pressing various keys while holding SysRq (Alt+PrintScreen).
