S2600CW - After System Boot Process "C7"

We have a new server with the S2600CW motherboard.  After the system boot process is complete, there is a "C7" character that remains in the bottom right hand corner of the screen.  This only shows with the on-board VGA connector, as we also have a PCIe video card installed.  Different characters show up in the bottom right-hand corner during POST, but I wouldn't expect to continue to see this after the Intel splash screen (press F2 for settings, F6 for boot menu, etc.)  Is this normal behavior?  BIOS is 01.01.0020.
