Boot LUN Number
If your boot device has multiple LUNs (Logical Unit Numbers) and
Multiple LUN Support
is
Enabled
, this option allows you to specify which LUN to boot from on your boot device.
0, 1, 2, 3, 4, 5, 6, 7
The ultra-wide SCSI controller boots with the displayed LUN (default
entry:
0).
SCSI Device Configuration
Initiate Sync Negotiation
Devices on the SCSI bus (including the SCSI controller) communicate intelligently with
each other. Before data is transferred across the bus, the sending (initiating) and
receiving (target) devices negotiate and agree on how long each piece of data will be, and
how many pieces will be sent at a time - that is, they agree on how fast to talk.
If you have operating problems with older SCSI devices, you should disable
Initiate Sync
Negotiation
. You may have to make settings on your SCSI devices (see the SCSI device
description).
When
Sync Negotiation
is disabled, the Ultra-Wide SCSI controller will automatically go
into synchronous mode if it receives a request from one of your SCSI devices. It can,
however, also exchange data with slow SCSI devices.
Yes
The function is enabled (default entry).
No
The function is disabled.
i
Synchronous data transfer is required for fast and ultra SCSI operation.
Initiate wide negotiation
This option determines whether the SCSI controller attempts 16-bit data transfer (Wide
SCSI) instead of 8-bit data transfer.
Only disable
Initiate Wide Negotiation
if you do not use any wide SCSI devices or if 8 bit
SCSI devices have problems during operation. You may have to make settings on your
SCSI devices (see the SCSI device description).
Fast SCSI devices, including the ultra-wide SCSI controller, are capable of transferring
data to and from the SCSI bus at speeds ranging up to 40 Mbyte/s.
Yes
The function is enabled (default entry).
No
The function is disabled.
Maximum Sync Transfer Rate
Fast SCSI devices (ultra-wide), including the ultra-wide SCSI controller, are capable of
transferring data to and from the SCSI bus at speeds ranging up to 40 Mbyte/s at
synchronous data transfer. If you have entered
Enabled
in the
Support for Ultra SCSI Speed
menu item, the transfer rate of 40 Mbyte/s is entered automatically.
