                    DC-680/690 Controller Not Being Seen


This is an informational bulletin.


The PCI IDE Card with TEKRAM DC-680/690 Controller not being seen in 
the Advantage! Adventure 80XX system.

TEKRAM DC-680/690 controllers are marketed today on at least two PCI 
IDE Cards.  These controllers are hardcoded to use interrupt 14.  
AST's and other Plug and Play BIOSes claim interrupt 14 for the on-board 
IDE controller.  
The TEKMAR controller used in the AST Advantage! Adventure systems is 
not compatible with Plug and Play BIOSes.
