Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 59
( using the actual address of another machine on the network, rather
than the one shown above).
If interrupts are running you should be presented a Rombug prompt at
the breakpoint address. You can type g to see if you get another
interrupt or k to kill the breakpoint.
Port Address Conflict
It is also possible that the port address used for this card is used by
another device in the system. If this is the case, the OS-9 command
netstat -in will not show the card as available.
The following netstat example shows a working network card
configured with IP address 182.52.109.25 and MAC address of
00.00.C0.91.4F.96.

How to modify the OS-9 descriptor
Edit the file
MWOS/OS9000/80386/PORTS/PCAT/SPF/SPE509/DEFS/spf_desc.h

Change the fields below as required.
INF_AUI = AUI Connection type
INF_BNC = BNC connection type
INF_UPT = 10BaseT (RJ45)
INF_EXT = Use same connection type determined in 3COM setup
