Well, a mic input is not good for more than 20 kHz or so bandwidth. For 100 MHz sampling, I think you will need some type of plug-in video/imaging card. It's more of a hardware issue than software; that's a fast rate and you have signal integrity and noise issues to deal with, especially in a PC environment. Maybe the Data Acquisition toolbox and TMW's supported hardware recommendations would be some things to look at.
