Hardware Options and Upgrades
The USB connectors on the notebook support USB 2.0- and 1.1-
compliant devices.
By default, USB devices function only while the operating
system is loaded. To use a USB keyboard or hub connected to a
USB connector on the notebook during startup (before Windows
loads) or in a non-Windows application or utility, enable USB
legacy support in the Setup utility. For more information about
using the Setup utility, see the “Using the Setup Utility” section
in Chapter 9.
