Initiate Sync Negotiation
This option determines whether the SCSI controller initiates
synchronous negotiation with the SCSI device.
When set to
Yes
, the SCSI controller initiates synchronous
negotiation with the SCSI device.
controller does not initiate synchronous negotiation.
controller, however, always responds to synchronous negotiation if
the SCSI device initiates it. The default setting is
Data is transferred in asynchronous mode if neither the SCSI
controller nor the SCSI peripheral negotiates for synchronous data
transfers.
Some older SCSI-1 devices do not support
synchronous negotiation. This may cause the
system to operate erratically or hang when the
Initiate Sync Negotiation is enabled. Set this
item to
Maximum Sync Transfer Rate
This option determines the maximum synchronous data transfer rate
that the SCSI controller can support. The SCSI controller supports
rates up to the Fast Wide SCSI maximum of 20.0 MB per second.
The default value is 20.0.
In most cases, you can use the maximum value of 20.0. However, if
the SCSI controller is not set to negotiate data transfer (i.e., Initiate
Sync Negotiation is set to
maximum rate that the SCSI controller accepts from the device
during negotiation. This is a standard SCSI protocol.
Some older SCSI-1 devices do not support Fast
SCSI data transfer rates 10.0, 8.0, and 6.7.
This may cause the system to operate
erratically or hang if the transfer rate is too high.
Select a Maximum Sync Transfer Rate of 5.0
for these devices.
