Windows 2000” on page 37.

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,and2930u2. 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
