BDM-610000082 Rev A Chapter 4: Using the cpuModule 61
Legacy Mode
When in this mode, the controller will be fixed to use two interrupts: IRQs 14 and 15. Similarly, the I/O address
of the controller will be fixed in the system. When in Legacy Mode, only a primary and secondary channel may
be used in the system.
Note Because Legacy Mode permits only a primary and secondary channel in the system, configuring
the PCIe/104 connector’s SATA links for Legacy Mode will disable the onboard SATA storage.
