X51, Windows 7, Black Screen/5 beeps

[Problem] Upgrading the Bios from A06 directly to A10 without first loading Bios A07 created the issue. After rebooting, the X51 screen was black and making 5 beeps.

[Workaround Easy]
* Power off the X51 and monitor
* Open the case cover
* Locate the CLEAR CMOS green jumper on the motherboard next to the PCIe x16 video card
* Remove the two pin jumper from pins 2/3 and place it on pins 1/2. Wait one minute
* Restore the CLEAR CMOS green jumper to its original pins 2/3
* Put the Riser Card Assembly back in place
* Close the case cover
* Power on the monitor, then the X51

[Workaround Tougher]
* Power off the X51 and monitor
* Remove the power cord from the rear of the X51
* Disconnect the monitor from the discrete video card
* Open the case cover
* Remove the discrete video card riser assembly from the motherboard
* Leave the cover off
* Connect the monitor to the onboard HDMI port on the rear of the X51
* Reconnect the power cord to the X51
* Turn on the monitor, then the X51
* Press F2 to Enter the BIOS
* Press F9 to load the BIOS Defaults
* Press F10 to Save the changes and exit the BIOS
* Power the X51 off when see the Dell logo and progress bar
* Reinstall the discrete video card riser assembly
* Close the case cover
* Connect the monitor to the discrete video card
* Power on the monitor, then the X51

[Final Fix]
* Never skip a Bios revision. Load them in order. We will release Bios revision A11 that should prevent the skipping of future Bios revisions
