            SUBJECT  : Duplexing With IBM Disk Controllers
               DATE  : 6/13/90
         OS VERSION  : 286 and 386
           REVISION  : 
      SHELL VERSION  : All

GENERAL INFORMATION  : According to Engineering you can not currently mix and 
match different types of controllers in a PS/2 fileserver.  Such as put a MFM 
and an ESDI controller in the same machine and expect to duplex.  Also you  
cannot duplex MFM with MFM or ESDI with ESDI.  This is true with both 286 and 
386 NetWare.  The reason is that they will not share interrupts.
 
However the IBM SCSI controller has the capability to be duplexed with another 
IBM SCSI controller.
