TITLE: Bravo MS and Alaris Matinee Video Card 
 
 
SUMMARY 

   A monitor that is connected to a Bravo MS system does not display
   graphics with a Matinee PCI video card.

   This issue affects the following system: 501774.


ISSUE 

   The computer monitor does not display text or graphics when the 
   Matinee PCI video card is installed in the computer.  The cursor 
   hangs in the upper left hand corner of the monitor after turning
   the system ON.


BACKGROUND 
 
   The Ramdac chip at location U3 on the Matinee video card is 
   incompatible with the computer system.


ACTION 
 
   Use Alaris's Matinee Pro video card.  To upgrade the card, contact
   Alaris's Technical Support Department at 510-770-5766 or 
   http://www.alaris.com.  Please address the message to 
   "Technical Support" when contacting Alaris via the website.


NOTES 
 
   1. The Ramdac chip uses two different suppliers, AT&T and ST.  
      The symptom occurs with the Ramdac chip that is manufactured 
      by AT&T.

   2. The Matinee Pro video card uses the Cirrus Logic CL-GD5446 video
      chipset.  The Ramdac chip is built into the chipset.
