Int 1A Fn 92  - PCmcia Socket Services - Write One                         [X]

   AH = 92h
   AL = adapter number
   BL = socket number (01h to maximum supported by adapter)
   BH = attributes (see AH=91h)
   CL/CX = value to write
   DX:SI = card address

Return: CF clear if successful
       AH destroyed
   CF set on error
       AH = error code (01h,07h,0Bh,12h,14h) (see AH=80h"PCMCIA")

Note:  this function is only valid for I/O-mapped sockets; it also does not
     implement Card Technology handling--use AH=94h when writing to
     non-RAM technologies
