Using Advanced Configuration Parameters

Advanced users may use software parameters to alter the
configuration of the Windows NT device drivers supplied by
Adaptec. All Windows NT configuration information is stored in a
data structure called the Registry. You can edit this information
through a tool called the Registry Editor.
Caution:
Do not edit your registry unless it is absolutely
!
necessary. If there is an error in your registry, your computer
may become nonfunctional.

Using Windows NT SCSI Parameters

Follow the instructions below to enter the registry values that affect
how the Windows NT SCSI manager interprets the generic
configuration information of SCSI device drivers. All SCSI host
adapters installed in your system are affected by the values you enter
here. A list of valid values follows:
Note:
The following value keys are case-sensitive and must
be entered exactly as shown.
DisableTaggedQueuing — A nonzero value indicates that the
SCSI host adapter disables tagged queueing for SCSI devices.
The data type for this value is REG_SZ.
DisableSynchronousTransfers — A nonzero value indicates
that the SCSI host adapter is not to initiate synchronous
negotiations (but it may still accept negotiations initiated by a
SCSI target). The data type for this value is REG_SZ.
DisableDisconnects — A nonzero value indicates that targets
are not permitted to disconnect during the execution of a SCSI
command. The data type for this value is REG_DWORD.
MaximumLogicalUnit — This can limit the scan for connected
devices on the SCSI bus. Valid values are 1 to 8. If 1 is specified,
the Windows NT SCSI manager assumes that no SCSI targets
support LUNs other than 0. Otherwise, LUNs from 0 to 8 are
scanned during system initialization. The data type for this
value is REG_DWORD.
