IBM ARTIC186 DOS and, OS/2, File, Entry, Special, Information, Creating, Address Considerations

Appendix			A.		Special	Configuration		Information	for	DOS and
OS/2
This		appendix			is specific to			the DOS and	OS/2	operating systems. It contains informa
following:
Ÿ	Creating			an	ICAPARM.PRM		file
Ÿ	Changing			your CONFIG.SYS			file
Ÿ	Ctrl+Alt+Del				reset	considerations
Ÿ	Selecting			an	interrupt		level
Ÿ	Shared-memory considerations
Note:		This		information applies only if you are using the IBM-supplied software.
Creating			an	ICAPARM.PRM		File

After installing the software, you can create a special parameter file (ICAPARM.PRM) t defaults used to initialize the adapter.

Note: This	file		is the same one used	by the	Realtime	Interface	Co-Processor Multipor
Model	2	adapters.
ICAPARM.PRM	is	a	small file that can be	created	with an	ASCII text	editor. It conta

each adapter installed. The following two examples show the makeup of the parameter installation with one adapter and the other for an installation with multiple adapters. specified in hexadecimal (h).

File

Entry

You need to add an entry to

the ICAPARM.PRM file only if

you want to change the f

values

or

the

logical

card

numbering. All

other fields are

ignored for the adapter.

Address Considerations

The

I/O address for PCI

adapters can

present

a

problem

for

ICAPARM.PRM

entries

assigned

are entirely up to the PCI BIOS. Because the lowest

I/O

address

assigned

the

adapter is 02A0h, the values 0000 through

00FFh

are

used

to identify

PCI

adapters

is

divided into two 4-bit fields. The upper

four

bits

define

which

PCI adapter (0

lower four bits define the particular instance of the adapter. Therefore,n

The logical card-numbering of an ISA adapter can be changed by changing the position ICAPARM.PRM file in relationship to the other ISA adapters (ISA adapters must have a greater that any PCI adapter). See “Example 2: Multiple IBM ARTIC Adapters” on page A-3
