Once the boot image is created you may boot OS-9 and use "netstat" to
see that all cards are active and ready for use. You should see entries
for enet0, enet1, enet2 and enet3 if you are using a quad card.

The AM79C961A driver is designed to work in systems where DMA
BUS MASTER mode is employed with respect to the AM79C961 or
AM79C973 interfaces.
The AM79C961A driver is PLUG & PLAY. Only the base address
should be defined to allow multiple card usage.
How to modify the OS-9 descriptor
1. Edit the file.
MWOS/OS9000/80386/PORTS/PCAT/SPF/SP79C961/DEFS/spf_d
esc.h, changing the line defining PORTADDR, which reads #define
PORTADDR 0x300 /* Base address of hardware */, to give
PORTADDR the desired value.
2. Next re-make the descriptor: change to the
MWOS/OS9000/80386/PORTS/PCAT/SPF/SP79C961 directory
and type the command os9make -f=spfdesc.mak
You have now created a new descriptor. The next time you run the
Wizard, it will use the new descriptor.
