Anyway, what I want to do is link my laptop to my desktop so i can rescue some stuff. Im running Xp on laptop, and 98 on desktop… what should i use to connect the two? I have a network adapter on one but not the other, and usb on both… Pleeese help coz you people are always right. Thanks in advance.
