IBM Portmaster RIC Adapter/A.
Installation Requirements
If the installation is done on a model 8580 (20 MHz) then please see -> ECA# 048 <-.
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."
