Installing and Configuring Enhanced OS-9
/* options for CONNTYPE: INF_AUI, INF_BNC, INF_UTP, INF_EXT (auto) */
#define CONNTYPEINF_EXT
Finally, remake the descriptor: change to the
MWOS/OS9000/80386/PORTS/PCAT/SPF/SPE509 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 LLE509_PORT_ADDRESS 0x340
#define LLE509_IF_VECTOR 0x43
as required by the system. For example, for IRQ10, here are the
changes required.
#define LLE509_PORT_ADDRESS 0x340
#define LLE509_IF_VECTOR 0x4a
The Wizard will automatically re-make the cnfgdata module.
