6.3.4 Boot Device Configuration
This option a llows you to choose which SCSI ID device ha s the Boot right
for system O.S.
6.3.5 SCSI Device Configuration
This option a llows you to configure certa in pa ra meters of ea ch SCSI
device on the SCSI bus.
Use the cursor keys (

to ma ke your selection.
◼
Initiate Sync Negotiation
This option determines whether the host a da pter initia tes synchronous
negotia tion with the SCSI device.
When set to
yes,
the host a da pter initia tes synchronous negotia tion with
the SCSI device . When set to
no
, the host a da pter does not initia te
synchronous negotia tion. The host a da pter , however, a lwa ys responds to
synchronous negotia tion if the SCSI device initia tes it . The defa ult setting
is yes.
Da ta is tra nsferred in a synchronous mode if neither the on boa rd SCSI nor
the SCSI periphera l negotia tes for synchronous da ta tra nsfers.
Note:
Some older SCSI-1 devices do not support
synchronousnegotia tion. This ma y ca use your computer to opera te
erra tica lly or ha ng if Initia te Sync Negotia tion is ena bled . Set
Initia te Sync Negotia tion to
no
for these devices.
◼
Maximum Sync Transfer Rate
This option determines the ma ximum synchronous da ta tra nsfer ra te tha t
the host a da pter ca n support. The host a da pter supports ra tes up to the
Ultra SCSI ma ximum of 20.0 MBytes / sec.
◼
Enable Disconnection
This option determines whether the host a da pter a llows a SCSI device to
disconnect from the SCSI bus ( sometimes ca lled Disconnect / Reconnect).
Disconnect / Reconnect a llows the host a da pter to perform other
opera tions on the SCSI bus while the SCSI device is tempora rily
disconnected.
When set to
yes
, the SCSI device ma y disconnect from the SCSI bus . The
SCSI device , however ,ma y choose not to disconnect , even if permitted
by the host a da pter ( this ca n usua lly be configured on the SCSI device).
When set to
no
, the SCSI device is not a llowed to disconnect from the
SCSI bus . The defa ult setting is
yes
.
You should lea ve Ena ble Disconnection set to
yes
if two or more SCSI
devices a re connected to the on boa rd SCSI port . This optimizes SCSI
