Abstract: A startup sequence in a computer system is initiated by detecting a bus reset event in an I/O device connected to a host, and responsively to the bus reset event communicating resources required to be allocated by the host. When a startup command from a host driver is not received within a predetermined bus reset count, the device autonomously changes its current configuration to a safe mode configuration, wherein fewer resources are required to be allocated relative to the current configuration. The safe mode configuration is communicated from the device to the host.
