Compaq Armada V300 Series Reference Manual page 96

Device drivers are programs or data files containing information
needed to run a specific PC Card. Most of the device drivers you
need are preinstalled on the computer.
In order to save available memory, some device drivers are
not enabled after being installed.
Some types of PC Cards, such as network cards, Global
Positioning System (GPS) cards, SCSI cards, audio cards, and
multifunction cards, require an additional PC Card–specific
software device driver to function properly. This software device
driver is provided on diskette by the PC Card manufacturer and
should be installed according to the manufacturer's instructions.
Do not install any other PC Card software on the computer such as
Card and Socket Services, even if prompted to do so.
To view or configure the adapter in your PC Card under
Windows 95 or Windows 98, access the Device Manager
(StartÆ SettingsÆControl PanelÆdouble-click SystemÆDevice
Manager), and select the appropriate device type for the card you
want to configure.
If your PC Card has never been inserted, a dialog box will
appear when you insert the card into the PC Card slot and will
automatically display setting information for the card.
PC Cards are powered accessories in a small form factor. When
PC Cards are installed in your computer, they draw power from
the system even when they are not in use.
