Configuration Setting Descriptions

CIS Memory Address

The CIS Memory requires a 256 KB segment of memory for drivers.

I/O Base Address

The I/O address space is used by the LAN PC Card for communication between the LAN PC Card and the notebook. The LAN PC Card uses 16 bytes of I/O space, starting at the I/O Base Address.

Make sure that no other device is using the same value (the default is 300h). The range is from 200h to 3A0h. For more information about resolving resource conflicts, see Chapter 3.

Interrupt Request Level

The IRQ is used by the LAN PC Card for communication between the LAN PC Card and the notebook. The LAN 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 LAN PC Card can operate on the other interrupt levels if necessary. If a conflict continues you might have to change the setting of other adapters or options that are in the notebook. For Toshiba notebooks set the interrupt to 11. For more information about resolving conflicts see Chapter 3.

Transceiver Type

The Transceiver Type can be Auto-Select, Coax (BNC), or TP (RJ-45). The default is Auto-Select. If the PC Card cannot automatically detect what type of cable is connected to the network, it will assign TP (RJ-45).

Network Driver Optimization

Network driver optimization can be selected for a DOS client, Windows and OS/2 client, server. Changing this option to match the OS in your notebook may improve performance.
