I/O Port Map
The PPM-C407 uses plug-and-play (PnP) BIOS resource allocation. Care must be taken
to avoid contention with resources allocated by the BIOS.
The PPM-C407 utilizes a Low Pin Count to Industry Standard Architecture bridge (LPC
to ISA Bridge) to address the PC/104 bus. Most legacy PC/104 modules are I/O mapped
and function as expected. The LPC controller is the subtractive agent of the Intel Legacy
Block. All transactions not claimed elsewhere are sent to the LPC controller. The LPC to
ISA Bridge does not implement bus mastering cycles or direct memory access (DMA).
The following tables contain the I/O ports used on the PPM-C407.
