Interrupt Request Level

The IRQ is used by the PC Card for communication
between the PC Card and the PC.
The 3C589D PC Card can operate on one of eight interrupt
levels: 3, 5, 7, 9, 10, 11, 12, or 15.
The preferred interrupt level is 10, but the PC Card can
operate on the other levels if necessary. If a conflict
continues, you may have to change the setting of other
adapters or options that are in the PC.

Transceiver Type

The Transceiver Type can be Auto-Sense, Coax, or
Twisted-Pair. The default is Auto Sense. If the PC Card
cannot automatically sense what type of cable is connected
to the network, it will assign Twisted-Pair.

Network Driver Optimization

Network driver optimization can be selected for a DOS,
Microsoft Windows, or IBM OS/2 client, or a server
environment. Changing this option to match your system
may improve the network performance. Using a larger
percentage of CPU resources under DOS improves network
throughput.

Power Management

The 3C589D PC Card can shut down in the absence of LAN
traffic to conserve power in your PC. Power management
can be enabled or disabled. The default is enabled.
