Introduction
The Adaptec®Ultra160 Family Manager Set is a set of software
drivers and other files that enable your Adaptec Ultra160 Family
host adapter to communicate with your computer. The Adaptec
Ultra160 Family Manager Set contains drivers for the following
operating systems:
■Microsoft Windows NT®
■Microsoft Windows® 95/98
■Novell NetWare
■SCO UnixWare
The remainder of this chapter includes a table that lists all Adaptec
host adapters and device drivers that make up the Adaptec Ultra160
Family, as well as the minimum requirements needed to install the
software.
The remaining chapters are organized by operating system. Each
chapter provides instructions on how to install the driver at the
same time you install your operating system. If your operating
system is already installed, instructions on updating or installing the
driver are also included. If you have problems installing and using
the driver, refer to the Troubleshooting sections, included at the end of
each chapter.

Microsoft Windows NT Installation
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.
!

2-6
Ultra160 Family Manager Set User’s Guide
■Maximum SGList — Specifies the maximum number of
Scatter/Gather elements. Valid values are 17-255. The data
type for this value is 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
If the Parameters Device keys already exist, skip to Step 8
below to begin entering values. If the keys do not yet exist, you
will need to create them by continuing with Step 4.
4 Click on the adpu160m key.
5 Select Add Key from the Edit menu; Type Parameters in the
Key Name edit box. Leave the Class edit box blank.
6 Click on the Parameters key.
7 Select Add Key from the Edit menu; Type Device in the Key
Name edit box. Leave the Class edit box blank.
To specify a certain host adapter, append Device with the
number of the host adapter. For example, type Device0 for the
first host adapter, Device1 for the second, etc. If you omit the
host adapter number, the configuration information applies to
all Ultra160 Family host adapters.
8 Click on the Device key.
9 Select Add Value from the Edit menu. In the Value Name edit
box, enter one of the valid parameter values. Make sure to
enter the appropriate data type for the value. To enter
additional values, repeat Steps 8 and 9.
Note:
Changes made with the Registry Editor do not take
effect until you shut down and then restart your system.

Using Driver-specific Parameters
To use the Registry Editor to enter adpu160m.sys driver-specific
parameters that affect the configuration information for Adaptec
SCSI PCI device drivers, follow the instructions below. A list of valid
parameters follows:
Note:
The following parameters are case-sensitive and must
be entered exactly as shown. When entering multiple
parameters, each parameter must be separated by a space.
■/INSTRUMENTATION—enables recording of I/O statistics
and errors. If this option is not specified, instrumentation
defaults to disabled. The data type for this value is REG_SZ.
■/INSTR_ERRLOG_Z=nnn—sets the maximum number of
error log entries, if /INSTRUMENTATION is enabled.If a
number is not specified, the maximum number or error log
entries defaults to 32. Valid values are 0-128. The data type for
this value is REG_SZ.
■/MAXTAGS=nnn—specifies the tagged command queue
depth. If a number is not specified, the tagged queue depth
defaults to 128. Valid values are 1-255. The data type for this
value is REG_SZ.
■/HOTPLUG —enables Hot-Plug PCI feature. If this option is
not specified, Hot-Plug PCI feature defaults to disabled.
To enter driver-specific 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\DriverParameters
If the Parameters, Device, and Driver Parameters keys already
exist, skip to Step 10 below to begin entering parameters. If the
keys do not yet exist, you will need to create them by
continuing with Step 4.

Hot-Plug PCI is supported by the Windows NT 4.0 driver
adpu160m.sys . You will need a system that supports Hot-Plug PCI
as well as associated Hot-Plug PCI application software in order for
Hot-Plug PCI to work. Do not enable the Hot-Plug PCI feature unless
your system is Hot-Plug PCI capable and you wish to use the Hot-
Plug PCI feature.
