Removing the Protector Card
If you have a diskette drive, a protector card has been
inserted in the diskette slot at the factory to protect the drive’s
read/write heads. To remove it, either flip up the latch or press
the release button to pop the card out part way. Then pull it all
the way out.
Save any protector cards you remove; you may want to reinsert
them later, if you transport your computer.
Connecting a Monitor
If you have a VGA monitor (or a multi-frequency monitor with
an analog connector), you can connect it to the computer’s
built-in VGA port. See “Using the VGA Interface,” below. If
you have any other type of monitor, skip to “Using a Display
Adapter Card,” below.
