SCSI Pass Through protocol as defined in EFI 1.1.
|
|
This protocol allows information about a SCSI channel to be collected,
|
|
and allows SCSI Request Packets to be sent to any SCSI devices on a SCSI
|
|
channel even if those devices are not boot devices. This protocol is attached
|
|
to the device handle of each SCSI channel in a system that the protocol
|
|
supports, and can be used for diagnostics. It may also be used to build
|
|
a Block I/O driver for SCSI hard drives and SCSI CD-ROM or DVD drives to
|
|
allow those devices to become boot devices.
