The process of adding USB 2.0 ports took no time and the backup system is fast. If you add USB 2.0 ports with a PCI port card, then you'll still have your USB 1.1 ports, so whatever is plugged into those can stay.

Turn off the computer, Take off the CPU case. How this is done depends on the CPU. If you lost or lost the manual, I'm sure your computer manufacturer has info online. Google it, if needed. Slide the PCI card into the open PCI slot.

Then you can cover up the CPU, but some people leave it off until turning on the computer and checking all is OK. When turning on this little feller, it found the new card right away and worked. I didn't even have to run the software. The card came with four USB ports, one of which holds the backup system. It took under two hours to back up the computer, faster and easier than the tape backup.
