Determine Your Computer's Operating System; Determine What Interface To Use - Plextor PX-750A Installation And User Manual

Determine Your Computer's Operating
System
To determine which operating system your personal computer uses:
1. In Windows, select the Start menu, then select Settings, then Control
Panel, and choose the System icon. You see the System Properties
window.
2. In the System Properties window, make sure the General tab is
selected. The System line shows details about your operating system.
(For example, "Windows 2000.")
NOTE: Your computer must be running Windows 2000 or Windows XP
(or Mac OS X). If you are not running one of these operating systems
you cannot use the PX-750UF. You cannot use the PX-750UF with
Windows 98 or Mac OS 9.

Determine What Interface to Use

You can use either USB 2.0 or FireWire. The built-in USB ports on
older computers (and even on inexpensive new ones) provide only
USB 1.1—that is, Full-Speed (12 Mbps) USB.
For optimum performance:
• If your PC does not have built-in USB 2.0, use the FireWire port, if
available.
• If you have neither USB 2.0 or FireWire, you can purchase and
install a third-party PCI USB 2.0 or FireWire plug-in host adapter
card.
• If you don't want to purchase a separate card, you can use your PC's
built-in USB 1.1 port. However this limits the CD-RW drive
performance of the Plextor PX-750UF to 4X write, 4X rewrite, and
6X read. DVD performance with USB 1.1 is 0.7X.
