- * The card is detected and initialized in one of several ways :
- * 1. Autoprobe (default) - since the board is memory mapped,
- * a BIOS signature is scanned for to locate the registers.
- * An interrupt is triggered to autoprobe for the interrupt
- * line.
- *
- * 2. With command line overrides - t128=address,irq may be
- * used on the LILO command line to override the defaults.
- *
- * 3. With the T128_OVERRIDE compile time define. This is
- * specified as an array of address, irq tuples. Ie, for
- * one board at the default 0xcc000 address, IRQ5, I could say
- * -DT128_OVERRIDE={{0xcc000, 5}}
- *
- * Note that if the override methods are used, place holders must
- * be specified for other boards in the system.
- *
- * T128/T128F jumper/dipswitch settings (note : on my sample, the switches
- * were epoxy'd shut, meaning I couldn't change the 0xcc000 base address) :
- *
- * T128 Sw7 Sw8 Sw6 = 0ws Sw5 = boot
- * T128F Sw6 Sw7 Sw5 = 0ws Sw4 = boot Sw8 = floppy disable
- * cc000 off off
- * c8000 off on
- * dc000 on off
- * d8000 on on
- *
- *
- * Interrupts
- * There is a 12 pin jumper block, jp1, numbered as follows :
- * T128 (JP1) T128F (J5)
- * 2 4 6 8 10 12 11 9 7 5 3 1
