AST RESEARCH, INC.        TECHNICAL BULLETIN # 1672          03/04/97 
 
 
 
TITLE:  Installing SCO on an Ascentia A
 
 
ISSUE 
 
   Some users may encounter difficulties installing SCO Open Server 
   5 on an Ascentia A system, when selecting the Media device. SCO 
   will expect to see the IDE CD-ROM drive as a slave on the primary 
   controller and will not find the CD-ROM.
   
   This issue affects all Ascentia A systems.    

 
BACKGROUND 
 
   SCO Open Server 5 uses an ATAPI driver to provide support for IDE 
   CD-ROM devices. This support is given by replacing the Western 
   Digital driver shipped with SCO. 
   
   The user can avoid installation problems by defining the 
   parameters for this driver.    

 
ACTION 
 
   Use the following command at the boot prompt:
   
     defbootstr ahslink=ATAPI Sdsk=wd(1,0,0,0) disable=dptr
   
   This command will allow SCO to pick up the CD-ROM and use it as 
   the install media for SCO.    

 
NOTES 
 
   N/A
