Unsigned driver load error
If an
unsigned driver cannot be loaded
message appears
on the screen, set the
HKCU\Software\Policies\ Microsoft\
Windows NT\Driver Signing
key to allow installation of
DOME drivers.
To install the driver
1. Select Start -> Settings -> Control Panel -> System.
The System Properties dialog box appears.
2. Select Hardware -> Driver Signing… in the
Device Manager section.
3. Select either Ignore or Warn to allow installation of the
DOME driver and other unsigned drivers.
• If you select Ignore, the installation program ignores the
lack of a valid Catalog file with a digital signature.
• If you select Warn, the installation displays the message
Digital Signature Not Found
and prompts you to
continue or cancel.
Impaired screen resolution
If one screen of a dual-headed board looks strange after you
change the resolution of another screen, make sure the sister
displays have the same resolution settings by taking one of
these actions:
• Boot into VGA mode and change settings on one screen to
match the other.
• Use the DOME tab to change the resolution. It automatically
changes the sister display resolution to match.
