Using Advanced Configuration Parameters Advanced users may use software parameters to alter the configuration of the Windows 2000 device drivers supplied by HP. All Windows 2000 configuration information is stored in a data structure supplied by Windows 2000, 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 2000 SCSI Parameters Follow the instructions below to enter the registry values that affect how the Windows 2000 SCSI manager interprets the generic configuration information of SCSI device drivers. Each driver has its own key reference in the registry. In this example, the Ultra160 key is used (adpu160m). The other keys are aic78xx, aic78u2, adf6u160, and 2930u2. All SCSI host adapters supported by the modified key 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. • DisableDisconnects - A nonzero value indicates that targets are not allowed to disconnect during the execution of a SCSI command. The data type for this value is REG_DWORD. 39

Using Advanced Configuration Parameters
Advanced users may use software parameters to alter the configuration of the
Windows 2000 device drivers supplied by HP. All Windows 2000 configuration
information is stored in a data structure supplied by Windows 2000, called the
Registry. You can edit this information through a tool called the Registry Editor
.
Using Windows 2000 SCSI Parameters
Follow the instructions below to enter the registry values that affect how the
Windows 2000 SCSI manager interprets the generic configuration information
of SCSI device drivers. Each driver has its own key reference in the registry. In
this example, the Ultra160 key is used (
adpu160m)
. The other keys are
aic78xx
,
aic78u2
,
adf6u160
, and
2930u2
. All SCSI host adapters supported
by the modified key 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.
•
DisableDisconnects
— A nonzero value indicates that targets are not
allowed to disconnect during the execution of a SCSI command. The
data type for this value is
REG_DWORD
.
CAUTION
Do not
edit your registry unless it is absolutely necessary.
If there is an error in your registry, your computer may
become nonfunctional
