Both the BT-956C and the BT-956CD have internal and external
con-
nectors and one
internal connector:

The BT-956C supports the single-ended SCSI interface with software
controlled active termination.
The BT-956CD supports the differential SCSI interface with standard
differential termination.

Host Adapter
The BT-956X complies with
Specification Rev. 2.0, operating at the
maximum
local bus rate of 132
in 32-bit data burst mode.
host adapters offer exceptionally high product reliability due to
reduced component count and lower power consumption. Minimized
command overhead results in faster command execution. Adapter BIOS
supports up to 8
capacity per disk.
Configuration
BT-956X configuration is handled by the
motherboard. However,
where the motherboard is non-compliant, further configuration may be
necessary. Read Appendix A, “Configuration for Non-Conforming
Motherboards,” for a more details.
Other operating parameters can be configured using the
Util-
ity, a menu-based tool residing in the adapter’s Read Only Memory
(ROM). In addition to its simplified configuration,
offers diag-
nostics and disk utilities.
Hardware Requirements
Your
computer needs:
n
One available
expansion slot
(master,
not slave) for each BT-956X be-
ing installed
At least one 3.5” floppy drive
n
DC power for an internal 3.5” SCSI drive or an external subsystem
You’ll need the following cables:
n
A
cable to connect the BT-956X to Wide SCSI external devices
n
A
flat ribbon cable to connect internal Wide SCSI devices to the
BT-956X
A 50-pin, flat ribbon cable to connect internal SCSI devices to the
BT-956X
An optional four-pin cable to connect the drive activity LED on the host
front panel to the BT-956X
The peripherals you are attaching to the BT-956X should be SCSI-2 Com-
mon Command Set (CCS) compatible.
Software Requirements
You may need the following software:
Software for hard drive set-up to perform partitioning and high-level
formatting
Operating system software for hard drives being installed
Device drivers if not already embedded in the operating system
By default the board jumpers are not configured, assuming motherboard
support for automatic adapter configuration.
