Appendix A. Special Configuration
Information
Note:
This appendix contains special configuration information for DOS
and OS/2. If you are using another operating system, see “Step
2. Download the Diagnostics and Operating System Support
Programs” on page 2-5.
This appendix contains information about the following.
Creating an ICAPARM.PRM file
– Adding an entry to the ICAPARM.PRM file for the PCI
co-processor adapter
– Base I/O address considerations
Changing your CONFIG.SYS file
Ctrl+Alt+Del reset considerations
Selecting an interrupt level for the PCI co-processor adapter
Shared-memory considerations.
Creating an ICAPARM.PRM File
After your software is installed, you can create a special parameter
file (ICAPARM.PRM) to change the defaults for PCI co-processor
adapter initialization. This is the same file used for the Realtime
Interface Co-Processor Multiport and Multiport, Model 2 adapters.
(For a detailed description of this file, refer to the
IBM Realtime
Interface Co-Processor OS/2 Support: User’s Guide or the IBM
Realtime Interface Co-Processor DOS Support: User’s Guide.)
ICAPARM.PRM is a small file you create with a text editor and
contains a single line of parameters for each Realtime Interface
Co-Processor installed, including each PCI co-processor adapter.
The following two examples—for one adapter installed and for
multiple adapters installed—will work satisfactorily in most cases. All
values are specified in hexadecimal (h).
