Hardware Installation
By itself, your CD-ROM drive is incapable of communicating with your computer.
You must use a hardware link that enables your drive to ‘‘talk’’ with the rest of your
computer.
Plextor’s 4PleX drives use a SCSI interface as their link. If you own a PC, there are four
ways in which you can make the SCSI connection:
1) Use a separate 8-bit or 16-bit SCSI interface board. This is the most common
method. We recommend using a 16-bit SCSI interface board to maximize
the drives potential.
2) Use a soundboard that also has a SCSI interface built onto it. This helps save
a slot in your computer by combining the functions of two boards (SCSI
interface board and soundboard) into one. The downside of this is that most
soundboards use only an 8-bit SCSI chip. If you need the performance a
16-bit SCSI interface board provides (see page 32), you’ll have to buy a
separate board.
3) If you have an external drive, use a parallel-to-SCSI interface. This is a device
that plugs into the parallel port (the one your printer normally is connected
to) of your computer. It is convenient, but typically at a cost of reduced
performance by your CD-ROM drive.
4) If you have an external drive and a portable computer with a PCMCIA slot,
use a PCMCIA-to-SCSI card. This is a small, credit-card size device that plugs
into the PCMCIA slot. It too is convenient, but again at a cost of reduced
drive performance.
