Chapter 7 Customizing your HP Jornada 127
Install PC Cards and CompactFlash Cards according to the
card manufacturer's instructions by inserting them into the
appropriate slot on your HP Jornada. You may also need to
install a software driver for a particular card. The software
drivers for Windows CE should be included with the card or
be available from the card manufacturer.
Many PC Cards use considerable power and can quickly drain your battery. Connect to AC
power while using PC Cards.
PC Card and CompactFlash memory modules appear as
folders in the My Handheld PC folder. The folder called
Storage card represents the first card you inserted, and the
folder called Storage card 1 represents the next card that
was inserted.
Connecting USB devices
USB devices connect to the Universal Serial Bus (USB) port
on your HP Jornada and typically include such peripherals
as mice or pointing devices, keyboards, and joysticks. When
connecting a USB device, you will need to install the software
driver(s) provided by the device manufacturer, and the USB
port on your HP Jornada needs to be enabled.
