9.6 USB flash drives
9.6.1 5MMUSB.xxxx-01
9.6.1.1 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 sequence; alternatively, the IDE
controllers can be disabled in BIOS. In most cases, this can be avoided by running "fdisk / mbr"
on the USB flash drive.
