Installing System Components 89
Internal USB Memory Key Connector
The system provides an internal USB connector located on the expansion-
card riser 2 board for use with a USB flash memory key (see Figure6-4). The
USB memory key can be used as a boot device, security key, or mass storage
device. To use the internal USB connector, the Internal USB Port option
must be enabled in the Integrated Devices screen of the System Setup
program.
To boot from the USB memory key, you must configure the USB memory key
with a boot image and then specify the USB memory key in the boot
sequence in the System Setup program. See "System Setup Options" on
page48. For information on creating a bootable file on the USB memory key,
see the user documentation that accompanied the USB memory key.
