7.1.2 PC/104 Configuration
When using add-on boards on the PC/104 bus, make sure that there are no resource conflicts in the
system. Carefully choose hardware interrupts, DMA channels, memory and I/O address ranges to
avoid resource conflicts, which are often the reason why a board or a feature does not function
correctly. See Appendix A: System Resource Allocations” for information about the resources
already used by the T-MOPSlcdSA.
You can configure different features for the PC/104 bus in the BIOS setup utility. Please refer to the
“ISA Bus Configuration Submenu”, the “PCI PnP Menu” and the “Cache & Shadow Configuration
Submenu” section in the “Appendix B: BIOS Operation” chapter.
7.2 PC/104 Stack
PC/104 adapter cards are mounted in a stack-through manner. Adapter cards are designed with
plugs on their undersides that mate with the PC/104 socket connectors of T-MOPSlcdSA. PC/104
adapters can support the socket connector version on their topside and allow additional stacking
of adapters.
Whenever possible, use the T-MOPSlcdSA as the top module of the PC/104 stack because the CPU
board usually has higher heat-dissipation requirements.
