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