Sync Transfer Rate – The setting for this option determines the maximum
synchronous data transfer rate that the channel can support.
The AIC–7896 has a 16-bit channel that provides an effective maximum
synchronous transfer rate of 80.0 Mbytes/sec (40.0 Mbytes/sec per 8-bit
channel).
The Maximum synchronous transfer rates available are dependent on the
Initiate Wide Negotiation setting. The available settings are shown below.
80.0 40.0
53.4 26.7
40.0 20.0
32.0 16.0
26.8 13.4
20.0 10.0
16.0 8.0
13.4 6.7
10.0 5.0

Initiate Wide Negotiation = yes Initiate Wide Negotiation = no
Some older SCSI-1 devices do not support
Fast or Ultra SCSI data transfer rates (20.0,
10.0, 8.0, and 6.7). This may cause your
computer to operate erratically or hang at the
higher transfer rates. Refer to the device’s
documentation and set the transfer rate
accordingly.
