■ A bootable DOS diskette with the FDISK and SYS programs. If SYS is not available,
FORMAT may be used, but all existing files on the USB flash media device will be lost.
1. Turn off the computer.
2. Insert the USB flash media device into one of the computer's USB ports and remove all other
USB storage devices except USB diskette drives.

into a diskette drive and turn on the computer to boot to the DOS diskette.
4. Run FDISK from the A:\ prompt by typing FDISK and pressing Enter. If prompted, click Yes
( Y ) to enable large disk support.
5. Enter Choice [ 5 ] to display the drives in the system. The USB flash media device will be the
drive that closely matches the size of one of the drives listed. It will usually be the last drive
in the list. Note the letter of the drive.
USB flash media device drive: __________
Ä
CAUTION: If a drive does not match the USB flash media device, do not proceed. Data loss can occur.
Check all USB ports for additional storage devices. If any are found, remove them, reboot the computer,
and proceed from step 4. If none are found, either the system does not support the USB flash media
device or the USB flash media device is defective. DO NOT proceed in attempting to make the USB flash
media device bootable.
6. Exit FDISK by pressing the
Esc
key to return to the A:\ prompt.

8. At the A:\ prompt, enter
SYS x:
where x represents the drive letter noted above.
Ä
CAUTION: Be sure that you have entered the correct drive letter for the USB flash media device.
After the system files have been transferred, SYS will return to the A:\ prompt. Go to
step 13.
9. Copy any files you want to keep from your USB flash media device to a temporary directory
on another drive (for example, the system's internal hard drive).
10. At the A:\ prompt, enter
FORMAT /S X:
where X represents the drive letter noted before.
Ä
CAUTION: Be sure that you have entered the correct drive letter for the USB flash media device.
FORMAT will display one or more warnings and ask you each time whether you want to
proceed. Enter
Y
each time. FORMAT will format the USB flash media device, add the
system files, and ask for a Volume Label.
11. Press
Enter
for no label or enter one if desired.
12. Copy any files you saved in step 9 back to your USB flash media device.

media device as drive C.
