Publication number: 20250036419Abstract: Methods, systems, and devices for providing computer implemented services are disclosed. To provide the computer implemented services, an identification of a startup of a data processing system may be made. Based on the identification, a determination may be made regarding whether a device is present in an expansion slot of the data processing system. If the device is present, then another determination may be made regarding whether identification information is able to be obtained from the device. If obtained, the identification information may be interpreted to obtain communication link bifurcation settings for the device. Default communication link training settings may then be updated based on the bifurcation settings to obtain updated training settings.
