/*
 * Attention! This file contains user-serviceable parts!
 * I recommend to make use of it...
 * If you feel helpless, look into linux/Documentation/cdrom/sbpcd
 * (good idea anyway, at least before mailing me).
 *
 * The definitions for the first controller can get overridden by
 * the kernel command line ("lilo boot option").
 * Examples:
 *                                 sbpcd=0x300,LaserMate
 *                             or
 *                                 sbpcd=0x230,SoundBlaster
 *                             or
 *                                 sbpcd=0x338,SoundScape
 *                             or
 *                                 sbpcd=0x2C0,Teac16bit
 *
 * If sbpcd gets used as a module, you can load it with
 *     insmod sbpcd.o sbpcd=0x300,0
 * or
 *     insmod sbpcd.o sbpcd=0x230,1
 * or
 *     insmod sbpcd.o sbpcd=0x338,2
 * or
 *     insmod sbpcd.o sbpcd=0x2C0,3
 * respective to override the configured address and type.

/*
 * define your CDROM port base address as CDROM_PORT
 * and specify the type of your interface card as SBPRO.
 *
 * address:
 * ========
 * SBPRO type addresses typically are 0x0230 (=0x220+0x10), 0x0250, ...
 * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
 * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
 * specify the REAL address here, not the configuration port address. Look
 * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
 * sbpcd auto-probe, if you are not firm with the address.
 * There are some soundcards on the market with 0x0630, 0x0650, ...; their
 * type is not obvious (both types are possible).
 *
 * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
 *          if your soundcard has its CDROM port above 0x300, specify
 *          that address and try SBPRO 0 first.
 *          if your SoundScape configuration port is at 0x330, specify
 *          0x338 and SBPRO 2.
 *
 * interface type:
 * ===============
 * set SBPRO to 1 for "true" SoundBlaster card
 * set SBPRO to 0 for "compatible" soundcards and
 *                for "poor" (no sound) interface cards.
 * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
 * set SBPRO to 3 for Teac 16bit interface cards
 *
 * Almost all "compatible" sound boards need to set SBPRO to 0.
 * If SBPRO is set wrong, the drives will get found - but any
 * data access will give errors (audio access will work).
 * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
 * interface cards need SBPRO 1.
 *
 * sound base:
 * ===========
 * The SOUND_BASE definition tells if we should try to turn the CD sound
 * channels on. It will only be of use regarding soundcards with a SbPro
 * compatible mixer.
 *
 * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
 *          #define SOUND_BASE 0     leaves the soundcard untouched
