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.
1. Select Start -> Settings -> Control Panel -> System.
The System Properties dialog box appears.
2. Click the Hardware tab, and then click 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 another screen’s resolution, make sure the sister displays
have the same resolution settings by doing one of the following:
• Boot into VGA mode and change settings on one screen to
match the other.
• Use the DOME tab to change resolution. It automatically
changes the sister display resolution to match.
