140 Enhanced OS-9 for X86 PCAT

Installing and Configuring Enhanced OS-9

PCI Configuration Information

By default the PCI system will search up to seven buses. On newer

motherboards, PCI slot devices are not bus zero. The maximum bus

number may be changed in

MWOS/OS9000/80386/PORTS/PCAT/systype.h.

The PCI library must be re-made as well in

MWOS/OS9000/80386/PORTS/PCAT/PCILIB. Running os9make from

this directory will re-create a new PCI library. You must also re-make

any drivers that require the new changes.

MWOS/OS9000/80386/PORTS/PCAT/systype.h

#defineISA_IOBASE0x00000000/* ISA Base Address */

#definePCI_CNF_ADR0x00000CF8/* PCI Configuration Address */

#definePCI_DATA_ADR0x00000CFC/* PCI Data Address */

#definePCI_IO_BASEISA_IOBASE/* PCI I/O Base */

#definePCI_MEM_BASE0x00000000/* PCI Memory Base */

#defineMAX_PCI_BUS_NUMBER7/* Max PCI BUS Number */

PCI Library User Guide

The following functions are contained in the PCI library, pcilib.l.

NoteNote

pcilib.l is compiled as port-specific. For example, for the PC-AT port,

this library is located in ’MWOS/OS9000/80386/PCAT/LIB/pcilib.l’.
