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.
