/*
|
||||
* The card is detected and initialized in one of several ways :
|
||||
* 1. Autoprobe (default) - There are many different models of
|
||||
* the Pro Audio Spectrum/Studio 16, and I only have one of
|
||||
* them, so this may require a little tweaking. An interrupt
|
||||
* is triggered to autoprobe for the interrupt line. Note:
|
||||
* with the newer model boards, the interrupt is set via
|
||||
* software after reset using the default_irq for the
|
||||
* current board number.
|
||||
*
|
||||
* 2. With command line overrides - pas16=port,irq may be
|
||||
* used on the LILO command line to override the defaults.
|
||||
*
|
||||
* 3. With the PAS16_OVERRIDE compile time define. This is
|
||||
* specified as an array of address, irq tuples. Ie, for
|
||||
* one board at the default 0x388 address, IRQ10, I could say
|
||||
* -DPAS16_OVERRIDE={{0x388, 10}}
|
||||
* NOTE: Untested.
|
||||
*
|
||||
* 4. When included as a module, with arguments passed on the command line:
|
||||
* pas16_irq=xx the interrupt
|
||||
* pas16_addr=xx the port
|
||||
* e.g. "modprobe pas16 pas16_addr=0x388 pas16_irq=5"
|
||||
*
|
||||
* Note that if the override methods are used, place holders must
|
||||
* be specified for other boards in the system.
|
||||
*
|
||||
*
|
||||
* Configuration notes :
|
||||
* The current driver does not support interrupt sharing with the
|
||||
* sound portion of the card. If you use the same irq for the
|
||||
* scsi port and sound you will have problems. Either use
|
||||
* a different irq for the scsi port or don't use interrupts
|
||||
* for the scsi port.
|
||||
*
|
||||
* If you have problems with your card not being recognized, use
|
||||
* the LILO command line override. Try to get it recognized without
|
||||
* interrupts. Ie, for a board at the default 0x388 base port,
|
||||
* boot: linux pas16=0x388,0
|
||||
*
|
||||
* NO_IRQ (0) should be specified for no interrupt,
|
||||
* IRQ_AUTO (254) to autoprobe for an IRQ line if overridden
|
||||
* on the command line.
