    Abstract: Example implementations relate to automatic diagnostic mode to identify a potential cause of a boot problem of a system. In an example, the automatic diagnostic mode iteratively isolates subsystems of the system in coordination with a baseboard management controller. For each iteration of subsystem isolation, a system boot is executed while a subsystem is isolated. The system boot is monitored against a watchdog timer of the baseboard management controller to determine if the system boot is successful. If the system boot is successful, the isolated subsystem is marked as a potential cause of the boot problem of the system. If the system boot is unsuccessful, the automatic diagnostic mode continues to iteratively isolate the subsystems.

    Abstract: A technique includes holding a bus interface of a removable device that is inserted into a connector of a computer system in a state to prevent the device from communicating with a communication link. The communication link is coupled to the connector and is associated with operating system access to the device. The method includes a baseboard management controller communicating with the device using a channel other than the communication link while the bus interface of the device is held in the state; the baseboard management controller performing a security operation corresponding to the device based on the communication with the device using the channel; and the baseboard management controller releasing the bus interface of the device from the state to allow the device to communicate with the communication link in response to the baseboard management controller completing the security operation.
