How to Update/Push Firmware 17
STEP 3: Use the Configured USB Key to Push the Firmware onto a Target Device
In this step, you will boot your target device from the configured USB key so
that the USB key will push the contents from the USB key onto the target
1. If you are changing the BIOS Setup Utility on the target device (for example, you are
not using the recommended one-time boot menu process because your device does
not support the one-time boot menu option), at this time you must configure the target
device to boot from the configured USB key as described in "How To Configure Your
Device to Boot from a Configured USB Key." If you are using the one-time boot menu
(recommended), you can skip this step.
2. Attach the configured USB key to the target device (be sure it is shut down and
disconnected from any network).
3. Power on the target device and boot from the configured USB key. If you are using the
recommended one-time boot menu process, at this time you must follow the one-time
boot menu instructions as described in "Most Users: Using the One-Time Boot Menu to
Boot from a Configured USB Key" (for most devices, press and hold the P key, select
the USB drive option that is displayed for your BIOS version, press Enter, and follow
the process prompts). CAUTION: If you are using a Wyse T50, use the instructions in
"T50 Users: Using the One-Time Boot Menu to Boot from a Configured USB Key."

To continue, type y and press Enter.

5. Once the push process is complete, you must reboot (press Enter and remove the
BIOS updates for Z90DW, Z90SW, Z90D7 and Z90S7 devices will happen
after the imaging is completed by Merlin (that is, after a reboot). Do not
power off the device until after the Merlin process completes the imaging and
the BIOS imaging is completed.
You can use the configured USB key to push the firmware onto as many
target devices as you want (repeat "STEP 3: Use the Configured USB Key to
Push the Firmware onto a Target Device").
