Hi, Thanks to Randy, I have found a good source of HD for upgrading my TP701. Does any one know if the 701 will support HD sized at 2.1GB? I am deciding between the 1.44GB and the 2.1GB 4LP by IBM. I am more worried about not being able to boot the computer than not being able to use the whole capacity. Any comment would be appreciated. Thanks. Eddy Lin
