IN EFI_EVENT Event OPTIONAL
)
/*++
Routine Description:
Implements EFI_SCSI_PASS_THRU_PROTOCOL.PassThru() function.
Arguments:
This: The EFI_SCSI_PASS_THRU_PROTOCOL instance.
Target: The Target ID of the ATAPI device to send the SCSI
Request Packet. To ATAPI devices attached on an IDE
Channel, Target ID 0 indicates Master device;Target
ID 1 indicates Slave device.
Lun: The LUN of the ATAPI device to send the SCSI Request
Packet. To the ATAPI device, Lun is always 0.
Packet: The SCSI Request Packet to send to the ATAPI device
specified by Target and Lun.
Event: If non-blocking I/O is not supported then Event is ignored,
and blocking I/O is performed.
If Event is NULL, then blocking I/O is performed.
If Event is not NULL and non blocking I/O is supported,
then non-blocking I/O is performed, and Event will be signaled
when the SCSI Request Packet completes.

/*++
Routine Description:
Used to retrieve the list of legal Target IDs for SCSI devices
on a SCSI channel.
Arguments:
This - Protocol instance pointer.
Target - On input, a pointer to the Target ID of a SCSI
device present on the SCSI channel. On output,
a pointer to the Target ID of the next SCSI device
present on a SCSI channel. An input value of
0xFFFFFFFF retrieves the Target ID of the first
SCSI device present on a SCSI channel.
Lun - On input, a pointer to the LUN of a SCSI device
present on the SCSI channel. On output, a pointer
to the LUN of the next SCSI device present on
a SCSI channel.
Returns:
EFI_SUCCESS - The Target ID and Lun of the next SCSI device
on the SCSI channel was returned in Target and Lun.
EFI_NOT_FOUND - There are no more SCSI devices on this SCSI channel.
EFI_INVALID_PARAMETER - Target is not 0xFFFFFFFF,and Target and Lun were not
returned on a previous call to GetNextDevice().

/*++
Routine Description:
Used to allocate and build a device path node for a SCSI device
on a SCSI channel. Would not build device path for a SCSI Host Controller.
Arguments:
This - Protocol instance pointer.
Target - The Target ID of the SCSI device for which
a device path node is to be allocated and built.
Lun - The LUN of the SCSI device for which a device
path node is to be allocated and built.
DevicePath - A pointer to a single device path node that
describes the SCSI device specified by
Target and Lun. This function is responsible
for allocating the buffer DevicePath with the boot
service AllocatePool(). It is the caller's
responsibility to free DevicePath when the caller
is finished with DevicePath.
Returns:
EFI_SUCCESS - The device path node that describes the SCSI device
specified by Target and Lun was allocated and
returned in DevicePath.
EFI_NOT_FOUND - The SCSI devices specified by Target and Lun does
not exist on the SCSI channel.
EFI_INVALID_PARAMETER - DevicePath is NULL.
EFI_OUT_OF_RESOURCES - There are not enough resources to allocate
DevicePath.

Routine Description:
Used to translate a device path node to a Target ID and LUN.
Arguments:
This - Protocol instance pointer.
DevicePath - A pointer to the device path node that
describes a SCSI device on the SCSI channel.
Target - A pointer to the Target ID of a SCSI device
on the SCSI channel.
Lun - A pointer to the LUN of a SCSI device on
the SCSI channel.
Returns:
