Initiate Sync Negotiation
Maximum Sync Transfer Rate
Enable Disconnection
007-4278-001
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. When set to no, the SCSI controller does not initiate synchronous negotiation. The
SCSI controller, however, always responds to synchronous negotiation if the SCSI device
initiates it. The default setting is yes.
Data is transferred in asynchronous mode if neither the SCSI controller nor the SCSI
peripheral negotiates for synchronous data transfers.
Note: Some older SCSI-1 devices do not support synchronous negotiation. This may
cause your computer to operate erratically or hang if Initiate Sync Negotiation is
enabled. Set Initiate Sync Negotiation to no for these devices.
This option determines the maximum synchronous data transfer rate that the SCSI
controller can support. The SCSI controller supports rates up to the maximum of 80.0
MBytes/sec. The default value is 80.0.
In most cases, you can use the maximum value of 80.0. If the SCSI controller is set not to
negotiate for synchronous data transfer (i.e., Initiate Sync Negotiation is set to no), then
the value selected here is the maximum rate that the SCSI controller accepts from the
device during negotiation. (This is standard SCSI protocol.)
Note: Some older SCSI-1 devices do not support Fast SCSI data transfer rates. This
may cause your computer to operate erratically or hang if the transfer rate is set too
high. Set Initiate Sync Negotiation to no for these devices.
This option determines whether the SCSI controller allows a SCSI device to disconnect
from the SCSI bus (sometimes called Disconnect/Reconnect). Disconnect/Reconnect
allows the SCSI controller to perform other operations on the SCSI bus while the SCSI
device is temporarily disconnected.
