6.1.1 General information
USB flash drives are storage media that are easy to exchange. Because of their high-speed data transfer (USB
2.0), USB flash drives are ideal for use as portable data storage. Without requiring additional drivers ("hot plugging",
except in the case of Windows 98SE), the USB flash drive can immediately act as an additional drive for reading
or writing data.
Information:
Due to the large number of USB flash drives available on the market as well as their short product life
cycle, we reserve the right to supply alternative products at any time. The following measures may
therefore be necessary in order to boot from these flash drives as well:
•
The flash drive must be reformatted or in some cases even repartitioned (set active partition).
•
The flash drive must be the first bootable device in the BIOS boot order; alternatively, the IDE
controllers can be disabled in BIOS. This can be avoided in most cases if the "fdisk /mbr"
command is additionally executed on the USB flash drive.
