1da177e4 LT |
26 | * The card is detected and initialized in one of several ways : |
27 | * 1. Autoprobe (default) - There are many different models of | |
28 | * the Pro Audio Spectrum/Studio 16, and I only have one of | |
29 | * them, so this may require a little tweaking. An interrupt | |
30 | * is triggered to autoprobe for the interrupt line. Note: | |
31 | * with the newer model boards, the interrupt is set via | |
32 | * software after reset using the default_irq for the | |
33 | * current board number. | |
34 | * | |
35 | * 2. With command line overrides - pas16=port,irq may be | |
36 | * used on the LILO command line to override the defaults. | |
37 | * | |
38 | * 3. With the PAS16_OVERRIDE compile time define. This is | |
39 | * specified as an array of address, irq tuples. Ie, for | |
40 | * one board at the default 0x388 address, IRQ10, I could say | |
41 | * -DPAS16_OVERRIDE={{0x388, 10}} | |
42 | * NOTE: Untested. | |
43 | * | |
44 | * 4. When included as a module, with arguments passed on the command line: | |
45 | * pas16_irq=xx the interrupt | |
46 | * pas16_addr=xx the port | |
47 | * e.g. "modprobe pas16 pas16_addr=0x388 pas16_irq=5" | |
48 | * | |
49 | * Note that if the override methods are used, place holders must | |
50 | * be specified for other boards in the system. | |
51 | * | |
52 | * | |
53 | * Configuration notes : | |
54 | * The current driver does not support interrupt sharing with the | |
55 | * sound portion of the card. If you use the same irq for the | |
56 | * scsi port and sound you will have problems. Either use | |
57 | * a different irq for the scsi port or don't use interrupts | |
58 | * for the scsi port. | |
59 | * | |
60 | * If you have problems with your card not being recognized, use | |
61 | * the LILO command line override. Try to get it recognized without | |
62 | * interrupts. Ie, for a board at the default 0x388 base port, | |
22f5f10d | 63 | * boot: linux pas16=0x388,0 |
1da177e4 | 64 | * |
22f5f10d | 65 | * NO_IRQ (0) should be specified for no interrupt, |
1da177e4 LT |
66 | * IRQ_AUTO (254) to autoprobe for an IRQ line if overridden |
67 | * on the command line. | |
