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
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.
•Maximum SGList — Specifies the maximum number of Scatter/Gather elements. Valid values are
REG_DWORD.
To enter Windows NT parameters, follow these steps:
1.Select Run from the Start button.
2.Type regedt32 and press Enter.
3.Open the registry list to the following location:
\HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\adpu160m\Parameters\Device
