Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 77
How to modify the OS-9 descriptor
Edit the file
MWOS/OS9000/80386/PORTS/PCAT/SPF/NE2000/DEFS/spf_desc.h.
Change the fields below as required.
/*
* From spf_desc.h
*/
#define PORTADDR0x00000340/* Base address of hardware */
#define VECTOR0x49/* Port vector */
/*
* PCI Specific Settings
*/
#define PCIINDEX0x00/* 0 picks first card */
#define PCIBUS0x00/* 0 indicates to search */
#define PCIDEV0x00/* 0 indicates to search */
Finally, remake the descriptor: change to the
MWOS/OS9000/80386/PORTS/PCAT/SPF/NE2000 directory and type:
C:> os9make -f=spfdesc.mak
Next time you run the Wizard the new descriptor will be used.
Low-level system changes
If system state debugging is used, you must change the low level
system by modifying the following lines from the file
MWOS/OS9000/80386/PORTS/PCAT/ROM/cnfgdata.des:
#define LLNE2000_PORT_ADDRESS0x340
#define LLNE2000_IF_VECTOR0x49
as required by the system. For example, for IRQ10, here are the
changes required.
#define LLNE2000_PORT_ADDRESS0x340
#define LLNE2000_IF_VECTOR0x4a
The Wizard will automatically re-make the cnfgdata module.
