computer’s manual to find out how to reset it to the faster speed. If that doesn’t
work you can also install a faster parallel port.
■ I/O and IRQ. The IRQ (interrupt request level) and I/O (input/
output) base address are the computer resources used by the parallel
port. The CD-Writer Plus drive requires a parallel port set to:
IRQ 7 with I/O base address 378, or
IRQ 5 with I/O base address 278
Most computers automatically assign these. But, depending on your
configuration, you may run into conflicts with other devices. For
example, another device (such as your sound card) may be assigned
the same settings. If there is a conflict, it must be corrected before
installing the drive.
To find out which device is in conflict:
In Windows 95, right-click on the My Computer icon, select
Properties, select the Device Manager tab, double-click on the
computer icon to see a list of which device is using each resource
setting on your computer.
■ For optimum performance, run SCANDISK.EXE and DEFRAG.EXE
on your hard drive before using your CD-Writer Plus drive for the first
time (see your Windows manual for more information). Then run
them periodically after that. These programs improve access times to
the hard drive, which will help improve system performance while
writing to and reading from the CD-Writer Plus drive.
NOTE: Refer to your computer manual or contact your computer vendor if you
have any questions about your computer’s configuration or capabilities.
