IBM Thinkpad 760ED won't recognize memory

I have an IBM Thinkpad 760ED that won't recognize any memory beyond the 8MB base memory. How do I get it to see the added memory module?

These machines are very picky about what type of Ram they use. It must be exactly the correct type not a cheaper type with the same specs.
4x64-60ns, 144p SO DIMM, 3.3v, EDO(64 meg chip maximum on this machine is 72 megs)

Thanks for the help. I have some old modules that fit, but I noticed that they are not 144 pin. They are 88 pin. I have one board that has 144 pin modules on it. I will try that one and see what happens. Thanks!!!

That did the trick! There was a small switch on the board that I had to change the position of---then it worked!!!

Thanks soooooo much for your help!!!!
