Initio INI-9100UW - Manual (Page 42)

4-5
Enable Disconnect. The host adapter uses this option to allow a
device to temporarily disconnect from the SCSI bus (referred to as
disconnect/reconnect). This allows the host adapter to perform other
functions on the bus while the device is temporarily disconnected. The
device and the host adapter can then reconnect when the bus is
needed. (yes)
Enable Wide Negotiation (INI-9100UW ONLY). This option
determines whether the host adapter initiates wide data transfer with
the specified SCSI device. However, not all SCSI devices can handle
wide data transfer properly and this may cause problems with your
system. If problems arise from wide SCSI negotiation, disable this
option. The normal setting for this option is enabled (yes).
