5How to Update/Push Firmware
In this chapter you will:
1. Ready Your Firmware - Ready the firmware image you want to use on your target
2. Configure a USB Key - Configure a USB key (that will update/push the firmware that
you load on it to target devices).
3. Use the Configured USB Key to Push Firmware - Use that same configured USB
key to push the firmware onto as many target devices that you want (you will boot from
it on other same model and flash size target devices).
The Update option is not supported for devices running Windows CE.
•Non-PXE Images - When a Non-PXE image is used to image, the thin client flash size
must be greater than the image size (for example, if a 512 MB image is converted to a
Non-PXE Image, then the thin client flash size must be 1 GB to accommodate the boot
•USB Key Size - Must be greater than the size of the firmware image plus all other
contents you intend to push to target devices; unless you use the compress feature of
the tool to fit your total contents - be aware that compression can take a significant
amount of time depending on the size of your total contents (USB key size up to 16 GB
has been tested—see "USB Keys - Troubleshooting Boot Issues").
•USB Key is Reformatted - During the USB key configuration process, the USB key
will be reformatted.
If you are planning to configure the USB key to update a firmware image, you
must obtain and ready the firmware you want to use for updating before you
start the Wyse USB Firmware Tool wizard. Wyse provides firmware for most
devices from its Software Downloads Web site at:
CE v6.x firmware must be downloaded from:
Firmware files are normally made available in .exe or .zip format and must be
extracted to a folder that is available to the Wyse USB Firmware Tool wizard.
