PC Card Subsystem
The system board has two PC Card slots that support the following
types of PC Cards:
16 bit PC Card Type–I, II, III 5V, 3.3V
CardBus PC Card Type–I, II, III 3.3V
DMA is not supported.
The maximum current per slot is:
500 mA at 5 V dc
500 mA at 3.3 V dc
50 mA at 12 V dc
The PCI1250 PCI-to-Cardbus Controller Unit

is used as the PC
Card controller in the system unit. The available interrupt levels are
IRQ 3, 4, 5, 7, 9, 10, 11, and 15.
The system unit resumes operation from suspend mode when it
receives the ‘RI_OUT’ signal. The Type I and Type II PC Cards can
be installed into either the upper or the lower slot, or into both slots
at the same time. The Type III PC Card, however, must be installed
only in the lower slot. The Type II PC card cannot be used in the
upper slot when a Type III PC Card is used.
Either of the PC Card slots accepts a Zoomed Video Card with
appropriate drivers provided by venders.
The PC Card slots are designed according to the PC Card standard
released in March 1997.
