5-4 CHAPTER 5: CHANGING CONFIGURATION SETTINGS

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.
