If you are using the driver as a module, you can specify your ports and IRQs like # insmod mcdx.o mcdx=0x300,11,0x304,5 and so on ("address,IRQ" pairs). This will override the configuration in mcdx.h. This driver: o handles XA and (hopefully) multi session CDs as well as ordinary CDs; o supports up to 5 drives (of course, you'll need free IRQs, i/o ports and slots); o plays audio This version doesn't support yet: o shared IRQs (but it seems to be possible - I've successfully connected two drives to the same irq. So it's `only' a problem of the driver.) This driver never will: o Read digital audio (i.e. copy directly), due to missing hardware features. heiko@lotte.sax.de
