SHIFTIN/SHIFTOUT should work for the 25aa1024. You will need to look at the data sheet for the correct modes and all of that stuff.

This page has a few example about SHIFTIN/OUT and SPI.

Thanks for the heads up! I don't know how I missed that sample ,the "spix.bas" to begin with. I guess I just had to scroll down a little more :/

Seeing how I dont have the time to find this out for a few days... what chip should I expect to be quicker the I2C or the SPI? Both will be running off of a 4 MHz clock.
