PC Card services handles all power management for PC Card NDIS miniports. The power-down and power-up system events are transparent to NDIS miniport drivers. When powering down the system, PC Card services maintains state information and disables power to the PC Card socket. When power resumes to the system, PC Card services issues a card-removal notification for all PC Card sockets with inserted cards. Then, the system checks the socket status and issues card-insertion notification for each socket with a card. This process tells a miniport driver that, when the power-up cycle starts, the driver is first unbounded and unloaded and then reloaded and rebound to the appropriate NDIS protocol.
In addition, a PC Card NIC may be removed at any time from the device, so the NDIS miniport driver should have time-outs on all operations that poll the card's registers.
