If you take out the DiskOnChip out of the socket, MAKE SURE YOU KNOW WHICH WAY IT GOES BACK IN. Two people have already fried theirs! (no big loss)
Slide a *small* flat-head type screwdriver under the DOC Chip, and then slowly lift the thing with even *gental* force.
Assuming most people know this, but for newbies here it is. The DiskOnChip has a little blue dot in one corner of the label. Make sure that lines up with the little white arrow on the Motherboard right beside one corner of the socket.
