+For now, AtapiPassThru driver in this package is to test Scsi Bus support:\r
+ScsiBus driver should support both/either ScsiPassThru and ExtScsiPassThru\r
+installed on a controller handle.\r
+ \r
+AtapiPassThru driver in this package can selectively produce ScsiPassThru\r
+and/or ExtScsiPassThru protocol based on feature flags of PcdSupportScsiPassThru\r
+and PcdExtScsiPassThru.\r
+\r
+Please note that AtapiPassThru driver has not been tuned to size optimal.\r
+Neither is it feature complete: several driver model protocols required\r
+by option ROM driver, e.g. EFI_DRIVER_SUPPORTED_EFI_VERSION_PROTOCOL Protocol. \r
