HARDWARE CONFIGURATION
PCI SLOT SELECT
The only hardware selectable option on the 4I60 is the PCI slot number. This is the equivalent to
choosing the motherboard slot a standard PCI card is installed into. The slot number also determines
the PCI interrupt line driven by the 4I60. Jumpers W3 and W4 determine the PCI slot number: Each
card in the PC/104-PLUS stack must have a different slot number selected. Some PC/104-PLUS
CPUs do not have all 4 slots available for PC/104-PLUS add-in cards. Note that PCI DMA channel 2
is shared by slots 3 and 4. Since the 4I60 is a bus master card it cannot be used in slot 3 if another bus
master card is installed in slot 4 and vice versa.
