Using the SCSI Subsystem
This section describes the basic operations you need to perform
to use your computer’s built-in SCSI II subsystem. The SCSI
subsystem consists of the following items:
0 Adaptec AIC-7770 Twin Channel SCSI-2 controller
0 Two S-bit SCSI channels provided on two SCSI interfaces
built into the main system board
0 One SCSI device cable for connecting up to 7 internal SCSI
devices
0 RISC-based Phase Engine Sequencer
0 SCSI BIOS located within the system BIOS
0 SCSI device drivers for DOS, Windows, OS/2, NetWare,
Windows NT, and SCO UNIX.
The SCSI-2 controller supports fast and narrow SCSI, and
transfers data at 10MB per second. Command execution takes
only 35 ps (microseconds), compared to 350 ps on other SCSI
controllers.
The system uses the controller as bus master slot 9 of the EISA
bus, allowing it to burst 32-bit data onto the I/O bus at up to
33MB per second and avoid I/O bus control and compatibility
problems. It also provides extended translation for hard disk
drives larger than 1GB capacity (up to 8GB) directly from the
system BIOS. In addition, the controller can handle four
simultaneous I/O tasks for Windows NT, UNIX or OS/2.
