134 	  This is the traditional Linux IO delay used for in/out_p.
138 	bool "port 0xed based port-IO delay"
140 	  Use port 0xed as the IO delay. This frees up port 0x80 which is
141 	  often used as a hardware-debug port.

146 	  Use udelay(2) as the IO delay method. This provides the delay
147 	  while not having any side-effect on the IO port space.
150 	bool "no port-IO delay"
152 	  No port-IO delay. Will break on old boxes that require port-IO
