Adaptec 7800 Family Manager

Using Advanced Configurable

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.
