Solution
To allow installation of Dome drivers, set the
HKCU\Software\Policies\Microsoft\Windows NT\
Driver Signing key.
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 message Digital Signature Not
Found appears and prompts you to continue or cancel.
Remove any existing Dome display driver before you install
a more recent version.
The Confirm File Replace dialog box appears if the
installation CD contains a file older than the one currently
on your system. Click No to the question Overwrite the
newer file? or click No to All.
You may need to remove the DX2 display controller to check
the DIP switch settings. You can enable VGA on the display
controller or use a separate VGA card. See
correct switch positions to enable or disable VGA, depending
on your system.
