Definitions of SCSISelect Settings
This section defines the SCSI device settings for the host
adapter and for each device on the SCSI bus.
SCSI Bus Interface Definitions
The following definitions are most likely to require
modification.
■
Host Adapter SCSI ID
—This option sets the SCSI ID
of the host adapter.
To give the host adapter the highest priority on the
SCSI bus, we recommend that you leave the host
adapter at its default setting of SCSI ID 7.
■
SCSI Parity Checking
—This option determines
whether the host adapter verifies the accuracy of data
transferred on the SCSI bus. The default setting is
Enabled.
If any SCSI device connected to the host adapter does
not support SCSI parity, disable SCSI Parity Checking
on the host adapter and all SCSI devices. To deter-
mine if a device supports SCSI parity, consult the
device documentation.
■
Host Adapter SCSI Termination
—This option sets
termination on the host adapter. You can set termina-
tion to Automatic, Enabled, or Disabled. In general, you
should leave this option set to its default setting of
Enabled.
SCSI Device Configuration Settings
SCSI device configuration settings allow you to configure
parameters for each device on the SCSI bus. To configure
a specific device, you must identify the SCSI ID assigned
to that device. To determine the SCSI ID of a device, see
Using the SCSI Disk Utilities on page 9.
■
Initiate Sync Negotiation
—This option determines
whether synchronous data transfer negotiation
between the host adapter and a device is initiated by
the host adapter.
The default setting is Yes (Enabled). Set Initiate Sync
Negotiation
to No for devices that do not support
Sync Negotiation.
■
Maximum Sync Transfer Rate
—This option sets the
maximum synchronous data transfer rate that the
host adapter supports. The host adapter supports
rates up to 10 MBytes/sec.
If Initiate Sync Negotiation is set to No, then the max-
imum synchronous transfer rate is the maximum rate
that the host adapter accepts from the device during
negotiation.
■
Enable Disconnection
—This option lets a SCSI
device temporarily disconnect the SCSI device from
the SCSI bus. This allows the host adapter to perform
other operations while the SCSI device is discon-
nected. The default setting is Yes. Set Enable Discon-
nection
to Yes if two or more SCSI devices are
connected to the host adapter.
Advanced Configuration Options
Plug and Play SCAM Support
—Only Windows 95 sup-
ports this option. This option allows the host adapter to
automatically assign SCSI IDs to SCSI devices that sup-
port the SCAM protocol.
Caution:
The default setting is Disabled. Most
non-SCAM legacy devices tolerate the SCAM
protocol, so you can enable this option even if
you have a non-SCAM device.
