Standard Mode SCSI ConfigurationThe view for Standard Mode is a simple selection for those variables which apply toall SCSI peripherals connected. This is shown in Figure 3-5. Normally, the default ofone device at SCSI ID 0 with normal default parameters is selected.Select Enable Parity Checking to allow the host adapter to generate parity ondata sent and check parity on data received on the SCSI bus.Select Initiate Synch Negotiation to allow the host adapter to attempt to use thefaster synchronous protocol for data transfers on the SCSI bus. The host adapter willnegotiate for a data transfer rate of 5 MBytes/second and an offset of 7. If deselected,the transfers will use the asynchronous protocol, unless the SCSI drive itself re-quests synchronous negotiation. If the SCSI drive negotiates for synchronous trans-fers, the host adapter will respond with a 5 MBytes/second data transfer rate andoffset of 7, or the data transfer rate and offset suggested by the peripheral device,whichever is lower.Select Enable Disconnection to allow a peripheral to go off-line while it completesa lengthy operation like a seek. This allows the host adapter to perform other opera-tions on the SCSI bus while the device is temporarily disconnected.Host Adapter Interface Mode ......
