Installing a DD3 or DD4 unit on a Dell machine will sometimes cause the client to fail to boot.

Cause: The Dell machine is failing to recognize the new hardware.

Corrective Action: Resetting the BIOS and Clearing the NVRAM is required. Please follow these steps:

1. Enter system setup by pressing the <F2> key while the system is booting up.
2. Once in the system setup, turn on all the lights on the keyboard by pressing the <Caps Lock> key, <Scroll Lock> key, and the <Num Lock> key.
3. Press the <Alt> and <F> keys at the same time (usually it is 1 time).
   You'll hear a system beep if done correctly.
4. Press the <Alt> and <E> keys at the same time (usually it is 3 times).
   You should only hear one beep. If you hear multiple beeps, repeat this step until only one beep is heard.
5. Press the <Alt> and <B> keys at the same time.
   The system reboots.
