Another example, used on modern desktops as well as laptops, is USB. Enable HOTPLUG and KMOD, and build a modular kernel.

Note that the answer to this question doesn't directly affect the kernel: saying N will just cause the configurator to skip all the questions about these CD-ROM drives. If you are unsure what you have, say Y and find out whether you have one of the following drives. For each of these drivers, a file Documentation/cdrom/{driver_name} exists. Especially in cases where you do not know exactly which kind of drive you have you should read there. Most of these drivers use a file drivers/cdrom/{driver_name}.h where you can define your interface parameters and switch some internal goodies. All these CD-ROM drivers are also usable as a module ( = code which can be inserted in and removed from the running kernel whenever you want). If you want to compile them as module, say M instead of Y and read <file:Documentation/modules.txt>. If you want to use any of these CD-ROM drivers, you also have to answer Y or M to "ISO 9660 CD-ROM file system support" below (this answer will get "defaulted" for you if you enable any of the Linux CD-ROM drivers). source "drivers/cdrom/Kconfig" endmenu source "drivers/md/Kconfig" source "drivers/message/fusion/Kconfig" source "drivers/ieee1394/Kconfig" source "drivers/message/i2o/Kconfig" source "net/Kconfig" menu "Network device support" depends on NET config NETDEVICES bool "Network device support" ---help--- You can say N here if you don't intend to connect your Linux box to any other computer at all or if all your connections will be over a telephone line with a modem either via UUCP (UUCP is a protocol to forward mail and news between unix hosts over telephone lines; read the UUCP-HOWTO, available from <http://www.linuxdoc.org/docs.html#howto>) or dialing up a shell account or a BBS, even using term (term is a program which gives you almost full Internet connectivity if you have a regular dial up shell account on some Internet connected Unix computer. Read <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). You'll have to say Y if your computer contains a network card that you want to use under Linux (make sure you know its name because you will be asked for it and read the Ethernet-HOWTO (especially if you plan to use more than one network card under Linux)) or if you want to use SLIP (Serial Line Internet Protocol is the protocol used to send Internet traffic over telephone lines or null modem cables) or CSLIP (compressed SLIP) or PPP (Point to Point Protocol, a better and newer replacement for SLIP) or PLIP (Parallel Line Internet Protocol is mainly used to create a mini network by connecting the parallel ports of two local machines) or AX.25/KISS (protocol for sending Internet traffic over amateur radio links).

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 <http://www.linuxdoc.org/docs.html#howto>. General information about the modular sound system is contained in the files <file:Documentation/sound/Introduction>. The file <file:Documentation/sound/README.OSS> 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 <http://www.roestock.demon.co.uk/isapnptools/>), then you need to compile the sound card support as a module ( = code which can be inserted in and removed from the running kernel whenever you want) and load that module after the PnP configuration is finished. To do this, say M here and read <file:Documentation/modules.txt> as well as <file:Documentation/sound/README.modules>; the module will be called soundcore.o. I'm told that even without a sound card, you can make your computer say more than an occasional beep, by programming the PC speaker.
