A short description of all available drivers follows:

Ø Intel Southbridge Drivers

Because Windows 95 does not recognize the Southbridge of the newer Intel chipsets (TX,
BX, ZX etc) this utility has to be run, it will update the necessary Windows files. (Only for
Windows 95)

Ø SOYO SpeedPro Busmaster Driver for Win 95/98

Without the busmaster drivers the CPU will need to be involved every time data is read from
or written to the Harddisk. The busmaster drivers make use of DMA (Direct Memory Access)
to relieve the CPU of this burden, thus speeding up the system.

The SOYO SpeedPro driver makes use of an advanced caching algorithm, which gives it an
advantage over other busmaster drivers.

Ø Intel Busmaster Drivers for Windows 95
Ø Intel Busmaster Drivers for Win NT
Ø Intel Busmaster Drivers for OS/2

These are the official busmaster drivers as supplied by Intel.

Note: Do NEVER install two types of busmaster drivers on your system, this will

lead to conflicts and system instability. Therefore, if you install the SOYO
SpeedPro Busmaster driver you can NOT install the Intel Busmaster drivers.
Before installing a new busmaster driver first UNINSTALL the old busmaster
driver.

Using Advanced Configurable Parameters

Advance users may use software parameters to alter the configuration of the Windows NT device drivers
sup0plied 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.

SY-D6IBA2

26

SCSI Utilities

Quick Start Guide

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 disabled 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 stall 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 17-

255. The data type for this value is REG_DWORD.

To enter Windows NT parameters, follow these steps:

1 Select [Run] from the File menu (Windows NT 3.5x), or Run from the [Start] button (Windows NT

Using Windows NT and the Host Adapter

This section contains useful information on using Windows NT and your host adapter.

Removing a Host Adapter

Removing a host adapter can be as simple as physically removing it from the slot when your computer is
shut down. Windows NT boots and functions properly in this configuration, but a warning message is
generated every time you boot Windows NT.

If you have removed a host adapter but still have other host adapters of the
same type installed in your computer, do not use Windows NT Setup to
remove the device driver.

To eliminate the warning message, you must update the Windows NT software configuration, as described
below:

Removing a Host Adapter in Windows NT 3.5x

1. Start the Windows NT Setup Program. There is a brief pause while Windows NT Setup scans your
hardware configuration.

2. Select the [Options] pull-down menu and then select [Add/Remove SCSI Adapters]. The SCSI
Adapter setup program displays a list of all host adapters currently installed.

3. Select the host adapter you want to remove and click the [Remove] button. When the Windows NT
Setup program asks you for confirmation, click [OK].

Because SCSI device drivers are loaded during system bootup and because they may be needed
to load Windows NT itself, a screen may appear warning you that Windows NT may not start if you
remove the SCSI adapter.

4. If you are sure you are removing the correct host adapter type, click [OK].

5. Return to Step3 to remove driver support for other types of host adapters, or click [Close] to exit the
SCSI adapters portion of Windows NT Setup.

6. Close the Windows NT Setup program. When the following message appears, click [OK] to exit:

The changes you have made will not take effect until the computer is restarted.

7. If this message does not appear, no changes have been made to the Windows NT system
configuration.

8. Restart the computer.

SY-D6IBA2

30

SCSI Utilities

Quick Start Guide

Note: Windows NT Setup does not delete the device driver from your system disk; it
only updates Windows NT software configuration information so that the device driver is

no longer loaded during system bootup.

Removing a Host Adapter in Windows NT 4.0

1. From the Control Panel, double-click the [SCSI Adapters] icon.

2. Click the [Drivers] tab.

3. Select the driver you are planning to remove. The driver appears as one of the following:
For Ultra SCSI:
Adaptec AHA-294X/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller (NT 4.0)
or
Adaptec AHA-294X/AHA-394x or AIC-78xx PCI SCSI Controller (NT 4.0)
or
Adaptec AHA-294X/AHA-394x or AIC-78xx PCI SCSI Controller.
For Ultra2 SCSI:
Adaptec AhA-294Xu2/AIC-7890\91 PCI Ultra2 SCSI Controller (NT 4.0)

4. Click the [Remove] button.

5. If you are sure you are removing the correct host adapter type, click [Yes].

6. Click [Yes] to restart the computer and initialize changes. Click [No] to return to the SCSI Adapters
window.

Note: Windows NT Setup does not delete the device driver from your system disk; it
only updates Windows NT software configuration information so that the device driver is

no longer loaded during system boot up.

Swapping a Host Adapter

Swapping a 7800 Family host adapter for non-7800 Family host adapter is similar to the procedure for
adding a host adapter. The important distinction is that you make all software configuration changes while
Windows NT is running and before you make the hardware changes.

Note: If you do not install the driver that comes with the new host adapter, it may result in

a Windows NT boot failure.

SY-D6IBA2

31

SCSI Utilities

Quick Start Guide

To swap adapters, follow these steps:

1. Install the driver for the 7800 Family host adapter by following the steps in Installing the Driver When
Windows NT is Already Installed.

It is not essential to remove the device driver for the host adapter you are replacing. Windows NT
dynamically detects the absence or presence of host adapter hardware, and no problems should
arise if you leave the existing device driver installed. You may remove the device driver later, after
you have successfully rebooted Windows NT. However, if you leave the driver installed, the system
alerts you with an error message of the extra device driver every time you boot. See Removing a
Host Adapter.

2. Once the new device driver is installed, shut down Windows NT and replace the existing host
adapter with the 7800 Family host adapter.

3. Restart your computer and Windows NT. It is possible that some drive letter assignments may
change from the previous configuration.
