(6) Click the [Inport/outport (I/O)] option button, and check that an IO port is available for NC Card.
There is no problem concerning the I/O port address if one or more following addresses set is
not used:
120-123, 140-143, 160-163, 180-183, 1A0-1A3, 1C0-1C3, 1E0-1E3, 200-203, 220-223,
240-243, 260-263, 280-283, 2A0-2A3, 2C0-2C3, 2E0-2E3, and 300-303. When all the I/O
port addresses are used by other hardware, change the IO port addresses of the hardware if
the addresses can be changed. If the addresses cannot be changed, the hardware must be
removed before NC Card can be installed.

available.
(a) C0000 - C7FFF
(b) C8000 - CFFFF

(d) D8000 - DFFFF
There is no problem concerning the memory if any of the above ranges is vacant. If none of
the ranges is vacant, change the settings of the hardware or memory driver being used to
reserve one of the above four ranges.

If Windows will not start up after carrying out the above procedures, delete all the NC System
Device drivers. If Windows will not start up even after deleting all the NC System Device Drivers,

Drivers again.
