pin out compact flash

Question

Whats the deal with the pin out that comes with the development boards for the compact flash peripheral. I want to implement a compact flash into a design and need to put the pin out of the compact flash in my schematic but i can't figure some of the pins out. I looked at the compact flash offical website to get the pinout for the connector I just don't know how to hook it up to the nios processor. There are 4 pins that are not accounted for. On the development board they wired the pins to proto1 headers but i not sure what to do with them. Plus some of the pins are connected different in the development board than a compact flash pinout says to connect them. Hoping someone can help me. I am implementing in true IDE mode.

PS. I have written and read just fine from the compact flash on the development board and written some software to do what i want but i&#39;m foundering in this aspect. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif
