The driver has not seen any maintainer activity or other work that
wasn't tree wide conversion or clenaups in the entire history of
the git tree.

/*

 * 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

 * 1 3 5 7 9  11	12 10 8 6 4 2

 *

 * 3   2-4

 * 5   1-3

 * 7   3-5

 * T128F only 

 * 10 8-10

 * 12 7-9

 * 14 10-12
