Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 25 | * The card is detected and initialized in one of several ways : |
| 26 | * 1. Autoprobe (default) - since the board is memory mapped, |
| 27 | * a BIOS signature is scanned for to locate the registers. |
| 28 | * An interrupt is triggered to autoprobe for the interrupt |
| 29 | * line. |
| 30 | * |
| 31 | * 2. With command line overrides - t128=address,irq may be |
| 32 | * used on the LILO command line to override the defaults. |
| 33 | * |
| 34 | * 3. With the T128_OVERRIDE compile time define. This is |
| 35 | * specified as an array of address, irq tuples. Ie, for |
| 36 | * one board at the default 0xcc000 address, IRQ5, I could say |
| 37 | * -DT128_OVERRIDE={{0xcc000, 5}} |
| 38 | * |
| 39 | * Note that if the override methods are used, place holders must |
| 40 | * be specified for other boards in the system. |
| 41 | * |
| 42 | * T128/T128F jumper/dipswitch settings (note : on my sample, the switches |
| 43 | * were epoxy'd shut, meaning I couldn't change the 0xcc000 base address) : |
| 44 | * |
| 45 | * T128 Sw7 Sw8 Sw6 = 0ws Sw5 = boot |
| 46 | * T128F Sw6 Sw7 Sw5 = 0ws Sw4 = boot Sw8 = floppy disable |
| 47 | * cc000 off off |
| 48 | * c8000 off on |
| 49 | * dc000 on off |
| 50 | * d8000 on on |
| 51 | * |
| 52 | * |
| 53 | * Interrupts |
| 54 | * There is a 12 pin jumper block, jp1, numbered as follows : |
| 55 | * T128 (JP1) T128F (J5) |
| 56 | * 2 4 6 8 10 12 11 9 7 5 3 1 |
| 57 | * 1 3 5 7 9 11 12 10 8 6 4 2 |
| 58 | * |
| 59 | * 3 2-4 |
| 60 | * 5 1-3 |
| 61 | * 7 3-5 |
| 62 | * T128F only |
| 63 | * 10 8-10 |
| 64 | * 12 7-9 |
