Merge with Linux 2.1.72, part 2.

+/*
+ * 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
