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
