IBM Portmaster RIC Adapter/A

For FRU-P/N's >> IBM Realtime Interface Coprocessor Option P/N

IBM Portmaster RIC Adapter/A.

Installation Requirements

  1.  Hardware 
     The Realtime Interface Co-Processor Portmaster Adapter/A can be installed in the following IBM systems :

     If the installation is done on a model 8580 (20 MHz) then please  see -> ECA# 048 <-.

  2.  Software   The following software or equivalent is required :

  3.   - OR -

 Setup Parameters 
 PHYSICAL CARD NUMBER
   The physical card number defines the I/O address range of the
   IBM Realtime Interface Co-processor Portmaster Adapter/A.
   The Physical Card Number determines the Card Base Address, however,
   the physical card number does not necessarily correspond with the
   logical card number.
   For example, the card in the first slot may be given
   any physical card number, but it will always be considered logical
   card 0. The preferred card number/address range is the lowest available.
 INTERRUPT LEVEL
   The interrupt level is the prioritized interrupt request line on which
   the IBM Realtime Interface Co-processor Portmaster Adapter/A will
   interrupt the Personal System 2. The interrupt priorities are as follows
   (greatest priority first): 9, 10, 11, 12, 3, 4, 7.
   The interrupt level may be shared with another adapter.
   The preferred interrupt level is 7.
 ARBITRATION LEVEL
   This field is the arbitration level for the IBM Realtime Interface
   Co-processor Portmaster Adapter/A Busmaster DMA transfers.
 FAIRNESS
   This field enables or disables Fairness feature of the IBM Realtime
   Interface Co-processor Portmaster Adapter/A busmaster DMA transfers.
   This field should normally be Enabled.
 SHARED STORAGE WINDOW
   The Shared Storage Window is an unused ROM or RAM address range that
   is used as a window into the RAM on the IBM Realtime Interface
   Coprocessor Portmaster Adapter/A."
