3D Pipes Screen Saver and Dual-Screen
AccelSTAR II Graphics
On a system with dual-screen AccelSTAR II graphics, the 3D Pipes screen saver does not
display. If you activate this screen saver, you will only see a black screen. A driver fix for
this problem is under investigation. When available, a revised driver will be posted to the
Support pages on the World Wide Web (http://www.intergraph.com/ics/) and to the
Intergraph Bulletin Board Service (1-256-730-8786).
Enabling PC Card Hard Disk Operation
Intergraph Computer Systems has found a resource conflict that keeps a PC Card hard disk
(ATA or AT type) from being configured by Windows NT 4.0. To enable operation of a PC
Card hard disk in a PC Card adapter, you must edit the Windows NT Registry.
WARNING
Be careful when making changes in the Registry. Any mistakes or incorrect changes
may cause serious operating system problems, and you may have to reinstall the
operating system. If the system becomes unusable after you have modified the
Registry, restart the system and try to use the Last Known Good configuration option to
undo the damage. See Windows NT documentation for more information on the Last
Known Good configuration option.

1. Start the Registry Editor (
