When set to Yes, the host adapter attempts 16-bit transfer. When set to No, 8-bit data transfer is used unless the SCSI device itself requests Wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is sued because the data path for Wide SCSI is twice the size of normal 8-bit SCSI. For example, a transfer rate of 10 Mbytes/sec becomes 20Mbytes/sec, and a transfer rate of 20 Mbytes/sec (Ultra SCSI) becomes 40 Mbytes/sec.

nMaximum Sync Transfer Rate – This option sets the maximum synchronous data transfer rate that the host adapter supports. The default setting is 20.0 for the Ultra Wide SCSI. The host adapter supports rate up to the Ultra SCSI maximum of 20.0 Mbytes/sec (Ultra Wide SCSI provides an effective maximum synchronous transfer rate of 40.0 Mbytes/sec). If your device is an Ultra SCSI device, you can use the maximum value of 20.0. If your device is not an Ultra SCSI device select a transfer rate of 10.0.

If the host adapter is set not to negotiate for synchronous data transfer (that is, Initiate Sync Negotiation is set to no), then the maximum synchronous transfer rate is the maxi- mum rate that the host adapter accepts from the device during negotiation. (This is standard SCSI protocol.).

nEnable Disconnection – This option determines whether the host adapter allows the SCSI device to disconnect from the SCSI bus (sometimes called Disconnect/Reconnect).

Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. The default setting is Yes.

You should leave Enable Disconnection set to yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only one SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance.

nSend Start Unit Command – This option determines whether the Start Unit Command is sent to the SCSI devices at boot up (most devices do not require this). The default setting is No.
