Although this lab starts with a working oppy drive installed in a PC a likely scenario in a classroom setting when building a system, you d obviously need to install one from scratch On a new system (or if you are reassembling the disassembled, non-production machine from 2), you d start this lab at Step 5 Step 1 Begin with the PC turned on and the standard Windows desktop displayed To verify that the oppy drive works, insert a known good oppy disk containing les into the drive, and then view the les on it by following these steps: a) Double-click the My Computer icon on the Desktop b) Double-click the 3 1/2 Floppy (A:) icon in the window (see Figure 11-1) c) Observe the les and folders displayed Do you see les displayed _________________________________________________________
Hint
If no les are displayed, try another oppy disk Also, be sure to insert the disk properly You should hear a ratcheting sound when you double-click the oppy drive icon This is the sound of the read mechanism opening the metal cover so that it can read the data on the disk

Lab Exercise 1101: Installing Floppy Drives 195
Step 2 Properly shut down the system, unplug the main power cable, and open the case following good ESD procedures Step 3 Carefully disconnect the two cables from the back of the oppy drive One is the four-wire cable from the power supply (with its mini connector), and the other is the at ribbon cable that carries the data to and from the drive
Warning
Be sure to notice the seven-wire twist in the ribbon cable before you disconnect it Is the twist closer to the drive or to the motherboard If you put this cable back on incorrectly, the oppy drive will not work The end with the twist (see the illustration) always goes closest to the oppy drive
Floppy B
Floppy A Floppy controller plug
Hint
If your lab has gone sleekly high-tech and uses rounded data cables rather than the traditional at ribbon cables, you can safely assume that the connector on the end will have a marking for the A: drive
Now disconnect the other end of the ribbon cable from the motherboard These cables can be quite rmly attached to the motherboard, so use caution! Grab the connector, or grab as close to the connector as you can, and pull straight up rmly but gently Sometimes a connector will seem to stick on one side make sure that you don t pull unevenly, or you may bend the pins on the motherboard How many wires make up the ribbon cable (Go ahead, count em!) ______________________________________________________________________________ Is one of the wires a different color from the rest, and if so, what does that mean ______________________________________________________________________________ Look at the motherboard where the cable was attached, and examine the pins How many pins do you count ______________________________________________________ Look at the shape of the connection

Figure 11-2 The orientation of the oppy drive connector on the motherboard
Is it symmetrical, meaning you can plug the connector in either direction, or is one side of the connector keyed to prevent you from inserting it backwards _____________________________ Locate pin 1 (where the colored wire attaches) and pin 34 The thirty-fourth pin is the drive change signal/disk change signal It indicates when a disk has been physically changed If this wire is broken or not connected, the system will read the initial disk placed in the oppy drive after power is applied and remember the contents for that disk, no matter how many times you change disks during a session, until you reboot the system Compare your motherboard connection for the oppy drive with the one shown in Figure 11-2 Step 4 Remove the oppy drive from the case There are so many different ways that oppy drives are held into system cases that it would be impossible to list all of the various carriers, caddies, bays, and so on that might be used to hold your oppy drive Almost all oppy drives are secured to these carriers, caddies, and bays with ne-threaded screws The threads on these screws are narrower than those on the screws commonly used to secure expansion cards and the case cover There should be two screws in each side of the oppy drive for support
