Technical Notes: Device Drivers
SCSI
The SCSI Parallel Interface is an industry standard parallel data bus that provides a fast, consistent method of connecting computers and peripheral devices. The SCSI Architecture Model-3 specification expands the term "SCSI" to define an architecture that treats devices that adhere to the SCSI Architecture Model specifications in a consistent manner, independent of the physical bus to which the device is attached. Mac OS X provides in-kernel drivers for compliant devices and, with the I/O Kit (Apple's object-oriented driver development framework), supports application-level access to devices that declare peripheral device types other than $00, $05, $07, or $0E. |
