* 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
