AST RESEARCH, INC.        TECHNICAL BULLETIN # 1604          11/12/96 
 
 
 
TITLE:  Advantage! 7000/9000 ISA Card Conflict
 
 
ISSUE 
 
   When using the "auto" setting for I/O resources in BIOS setup, 
   Windows 95 is permitted to assign the resources.  Depending on 
   the resource allocations which are assigned by Windows 95, 
   conflicts may occur with ISA legacy devices.  These allocations 
   may change when the system is rebooted.
   
   This issue affects the following systems: 503079, 503080, 503082, 
   503083, 503084, 503086, 503087, 503152, 503116, and 503118.    

 
BACKGROUND 
 
   N/A    

 
ACTION 
 
   If conflicts occur, manually configure the jumpers on the legacy 
   card to a non-conflicting I/O address.    

 
NOTES 
 
   The issue mentioned in this bulletin does not affect the 
   performance of the operating system.
   
   The BIOS default values use manual resource settings for devices 
   such as the on-board serial ports, to ensure that the system 
   behaves consistently under most conditions.  
   When using an ISA legacy device in the system, it may be 
   necessary to reassign those resources to avoid conflicts with the 
   ISA legacy device.
