Technologies are disclosed herein that allow for utilization of memory channel storage (“MCS”) devices in a computing system. The address range for the MCS device may be reserved during an initial boot phase of the computing system, even if the MCS is not fully accessible during the initial boot phase, due to storage of prior MCS address data in non-volatile memory. If changes to the address are detected in a later boot phase, the stored information may be updated and a reboot requested.
