Connecting Your HP SureStore CD-Writer Plus Drive - C4358-90100

Installation Guide
SPP mode allows the CD-Writer drive to run at up to a 2x read
speed and up to a 1x write speed if the other minimum
system requirements are met.
EPP and ECP modes allow the CD-Writer drive to run at up to
a 6x read speed and a 2x write speed if the other minimum
system requirements are met.
TIP: Check your computers specifications to see which kind
of parallel port was installed. Sometimes a fast ECP/EPP port
will be set up as a slow standard mode port at the factory (for
example, some HP Vectra models). Check your computers
manual to find out how to reset it to the faster speed. If that
doesnt 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 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
drive for the first time (see your Windows manual for more
information). Then run them periodically after that. These
