You have one RAM slot in your iBook. You need to remove any RAM you have in there and install a 1 GB SO-DIMM module that is PC2100 or PC2700 type RAM. Make sure it is an SO-DIMM, as that is the laptop memory your iBook takes. With the 128 MB built-in, you will have 1.12 GB under the hood. I did it to my laptop, and no problems whatsoever. --Joe!
