6.1.2.1 General information
USB
flash drives are easily replaceable storage media. Due to the fast data transfer (
USB
2.0),
USB
flash drives
offer optimal values for use as portable storage media. Without additional drivers, the
USB
flash drive immediately
reports itself as another drive from which data
can
be read or to which data
can
be written (hot plugging).
Information:
Due to the large number of
USB
flash drives available on the market and their short lifecycles, we
reserve the right to supply alternative products. It may therefore be necessary to take the following
measures in order to also boot from these
USB
flash drives:
•
The
USB
flash drive must be reformatted or, in some cases, repartitioned (set partition as ac-
tive).
•
The
USB
flash drive must be in the first position in the boot order; alternatively, the
IDE
con-
trollers
can
be disabled in
BIOS
. In most cases, this
can
be avoided by running "fdisk / mbr"
on the
USB
flash drive.
