Internal USB Memory Key
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 "Boot Settings Screen" on
page 63. For information on creating a bootable file on the USB memory key,
see the user documentation that accompanied the USB memory key.
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and

by your warranty. Read and follow the safety instructions that came with the
product.
NOTE:
To avoid interference with other components, the maximum allowable
dimensions of the USB key are 24 mm (.94 in) wide x 79 mm (3.11 in) long x 8.6 mm
