CIS Memory Address
The CIS Memory requires a 256 B segment of memory.
I/O Base Address
The I/O address space is used by the CardBus PC Card for
communication between the CardBus PC Card and the
notebook. The CardBus PC Card uses 64 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 3000h). For more information about
resolving Resource conflicts, see Chapter 3.
Interrupt Request Level
To change the IRQ is used by the CardBus PC Card for
communication between the CardBus PC Card and the
notebook.
The CardBus PC Card can operate on one of six interrupt
levels: 5, 7, 9, 10, 11, or 12.
The preferred interrupt level is 9, but the CardBus 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 resource conflicts,
see Chapter 3.
Displaying Configuration
If you are running Windows 95 or Windows NT, use the
3Com PC Card Diagnostics program to display configuration
information.
Otherwise, use the 3Com DOS Configuration program
described in the INSTRUCT.TXT file in the Help directory on
the LAN Installation Disk.
