2222Routine Description:
2223
2224 This function is called by the OS-specific port driver after
2225 the necessary storage has been allocated, to gather information
2226 about the adapter's configuration.
2227
2228Arguments:
2229
2230 HwDeviceExtension - HBA miniport driver's adapter data storage
2231 Context - Address of adapter count
2232 ArgumentString - Used to determine whether driver is client of ntldr or crash dump utility.
2233 ConfigInfo - Configuration information structure describing HBA
2234 Again - Indicates search for adapters to continue
