Sysprep installation does not work
Description
A Sysprep installation of Microsoft Windows* does not work with the IntelŽ Application Accelerator.

Solution
This is expected behavior. The IntelŽ Application Accelerator does not support a sysprep installation.

Intel Application Accelerator can be installed after the operating system. Installation of the Intel Application Accelerator can also be automated via the [GuiRunOnce] section of the SYSPREP.INF file in order to run a silent installation. Information on command line switches for silent installation of Intel Application Accelerator is available in the readme.


Start menu shortcuts do not function properly
Solution
There may be a special character, such as an apostrophe, in the installation path.

To resolve this issue, uninstall and reinstall the software without specifying a special character in the installation path name. You can also manually correct the path using the shortcut properties.

Troubleshooting compatibility issues with CD-RW devices
Description
The following suggestions have been shown to be effective in correcting most compatibility issues between the IntelŽ Application Accelerator and CD-RW devices:
  • Upgrade your CD recording software
    CD recording software publishers frequently post patches to their software. Typically, updating to the most current version with the latest patches will help with compatibility issues. Check with your CD recording software manufacturer to see if patches or updates are available.
  • Update the device drivers or utility
    Some CD-RW devices have drivers or utilities associated with them. Check with your drive manufacturer to determine if this step is applicable or if updates are available.
  • Update your motherboard BIOS
    An ATAPI CD-RW device may not be properly detected due to a BIOS issue. Contact your motherboard or system manufacturer to see if a BIOS update is available for your specific motherboard.
  • Update the firmware on the device
    CD-RW devices have internal software called "firmware" that can usually be obtained from the device manufacturer. Firmware updates can correct a wide variety of issues.
  • Lower the transfer mode limit
    Some ATAPI CD-RW drives have issues when operating in DMA mode or when using a higher speed transfer mode, such as UDMA-2 (ATA-33). Lowering the transfer mode limit to DMA MW-2 or PIO-4, using the Intel Application Accelerator diagnostic utility, may help to resolve some CD-RW issues.
  • Test with Intel Application Accelerator un-installed
    Temporarily un-installing the Intel Application Accelerator helps to determine if the issue also occurs with the native Microsoft* IDE driver that comes with Windows*. See the Readme.txt for un install instructions.
    Important Note The steps listed below are for qualified and trained professionals only. Please do not follow the steps listed below unless you are a qualified and trained professional. Only qualified and trained professionals should open a computer system.
  • Modify the Master/Slave configuration
    ATA devices that share the same cable can sometimes conflict with one another. Some devices work better when they are configured as the Master device or the Slave device on the cable. Some devices work best when they are the only device on the cable. Typically, jumpers on the back of the ATA device are used to set the Master/Slave configuration. Consult the ATA device documentation to determine the appropriate jumper configuration to use.
  • Cabling
    Sometimes, physical components, such as ATA cables, may be defective or unsuitable for the required configuration. If you have a spare cable, try swapping cables temporarily to see if your issue is resolved. The issue may be resolved by using a 40-pin, 80-conductor cable where only a 40-pin, 40-conductor cable is required. Some devices are more sensitive to electrical noise issues and using a 40-pin, 80-conductor cable may help.

After installing IntelŽ Application Accelerator, the "Advanced Settings" tab with the DMA checkbox no longer appears
Description
This is expected behavior. After the Intel Application Accelerator is installed, the DMA checkbox is no longer needed. The Intel Application Accelerator will enable the maximum transfer mode for each drive connected to the IDE channel and you can use the diagnostic utility to manually set the transfer mode.

Does not install on Windows NT 4.0* with IntelŽ ICH4
Description
The IntelŽ Application Accelerator does not install during an unattended installation of Microsoft Windows NT 4.0* on a system with the IntelŽ 82801DB I/O controller hub (ICH4).

Solution
To install the driver using the unattended installation method, add the following entry to the cmdlines.txt file: IATA_CD -A -S

Note Substitute IATA_CD with the name of the Intel Application Accelerator self-extracting executable that you are using.

Hard drive "squeal" sound at shutdown
Description
A distinct hard drive "squeal" sound occurs when a laptop system is shut down.

Solution
Intel recommends that you install the Microsoft Windows* storage driver to address this issue. This can be accomplished by uninstalling the IntelŽ Application Accelerator software.

The cause of this issue is unknown, but it appears to be an acoustic issue.


Nero InfoTool* shows incorrect serial or parallel ATA configuration
Description
Nero* InfoTool* may display incorrect system configuration and device information if the IntelŽ Application Accelerator is also installed on the system. The incorrect information may include:
  • All devices are displayed on the primary channel
  • CD or DVD devices appear to have DMA turned off

Solution
To determine the current configuration of the ATA devices, run the Intel Application Accelerator diagnostic utility.


How to troubleshoot issues with disappearing devices
Description
IntelŽ Application Accelerator version 2.3 contains a special installation switch. This switch can assist in troubleshooting issues where devices disappear from Windows* Explorer* and/or My Computer*. Some customers have also reported that this has helped resolve blue screen errors.

This installation switch modifies the installation parameters and is similar to running in "Safe Mode" (built into Windows*). Using this installation switch will cause all the devices currently installed in your system to run at a standard PIO transfer mode rather than at their optimal transfer mode. Having the devices run at a standard PIO transfer mode may resolve issues such as devices disappearing.

Note Please be aware that when operating in PIO mode, your system may operate more slowly than before. It may also take longer to boot up. This is only temporary and can easily be corrected by changing the transfer modes to a higher setting at a later date (described in Step #2 below).


Step 1 - Installing Using Switch
In order to install the Intel Application Accelerator using this installation switch, please complete the following steps:

  1. If you haven't done so already, or if it has been removed from your system, download version 2.3 of the Intel Application Accelerator.

  2. Once the Intel Application Accelerator has been successfully downloaded, go to Start>Run and type the command line below for the appropriate language (without the quotation marks):

      English:
      "C:\Download_Location\iaa23_enu.exe -A -PIO_ALL"

      Multi-language:
      "C:\Download_Location\iaa23_multi.exe -A -PIO_ALL"

  3. Reboot the system when prompted.


This will install the Intel Application Accelerator and at the same time will configure any devices attached to the chipset's controller to run at a lower PIO transfer mode.

Step 2 - Raising the Transfer Speeds
If this corrects the issues you were previously experiencing, it is a good indication that one of the devices currently installed in your system is not fully capable of running at its optimal transfer mode. We recommend completing the following steps:

  1. Use the Intel Application Accelerator diagnostic utility to increase the transfer modes for each of the devices, one setting at a time. (Increasing the transfer modes involves changing from PIO mode to the faster UDMA modes). This should be done one device at a time; we recommend beginning with the Primary Hard Drive. Additional information on transfer modes and their associated speeds can be found on page 31 of the Intel Application Accelerator's User's Manual.

  2. Beginning with the Primary Hard Drive, raise the transfer mode for that device one setting at a time until you have reached the maximum setting supported by that device.

  3. Once you have reached the maximum setting for a device, proceed to the next device. It is important to test the system each time in order to verify if increasing each device's transfer mode will reproduce the issues.

    Please contact the device manufacturer for information on which transfer modes their devices support and reasons why a device may behave differently at faster transfer modes.

How to change Automatic Acoustic Management settings
If your hard drive supports Automatic Acoustic Management (AAM), you can use the following instructions to change the AAM settings for your hard drive:
Note Decreasing the hard drive's noise level is accomplished by decreasing the seek rates, which may cause a slight performance degradation.
  1. Launch the IntelŽ Application Accelerator diagnostic utility (Start / Programs / Intel(R) Application Accelerator / Intel(R) Application Accelerator).
  2. Click on the desired hard drive under Devices.
  3. Under Parameters, look for Auto-Acoustic Management. If your hard drive supports AAM, you should see a wrench icon immediately to the left of the Auto-Acoustic Management string. If the message "Feature not supported by device" appears , the hard drive does not support AAM.
  4. 4. Double-click on the wrench icon immediately to the left of Auto-Acoustic Management.
  5. Click on the drop-down selection under Parameter Data to change the AAM setting.

Here is a brief explanation of each setting:

  • Maximum performance: Best hard drive performance with Auto-Acoustic Management enabled
  • Minimum Acoustic Output: Minimum audible noise level, provides slower seek rates than the Maximum Performance selection
  • Disabled: Best hard drive performance without Auto-Acoustic Management enabled, provides faster seek rates than the Maximum Performance selection, but also increases the hard drive's noise level

Using hard drives that are larger than 137GB (48-bit LBA)
Overview
The following operating systems do not provide native support for hard drives that are larger than 137GB (also referred to as 48-bit logical block addressing or 48-bit LBA).
  • Windows XP*
  • Windows 2000*
  • Windows Me*
  • Windows 98* and Windows 98 SE*
  • Windows NT 4.0*

Windows XP Service Pack 1 and Windows 2000 Service Pack 4 add support for 48-bit LBA; please contact Microsoft* for additional information. Otherwise, in order to enable support for hard drives that are larger than 137GB, you will need to install the Intel(R) Application Accelerator or install a 3rd party 48-bit LBA controller card.

BIOS support
Windows XP, Windows 2000: 48-bit LBA BIOS support is not necessary Windows Me, Windows 98SE, and Windows 98: If your BIOS does not currently support 48-bit LBA, you will need to obtain an updated BIOS from your motherboard or system manufacturer.

System configuration
In order for your system to recognize hard drives that are larger than 137GB, use one of the following configurations:

Large drive as primary drive (boot drive)

  1. Install the operating system.
  2. Install the Intel Application Accelerator.
  3. Use a third-party partitioning software application to expand the partition to the full capacity of the hard drive or create additional partition(s) that use the remaining capacity.

Large drive as secondary drive

  1. Install the large hard drive as a slave device.
  2. Install the Intel Application Accelerator on the primary hard drive.

Uninstallation information
If you uninstall the Intel Application Accelerator, you will not be able to access any data located in the 48-bit LBA region (above 137GB). Uninstalling the Intel Application Accelerator removes the 48-bit support that was previously enabled.

If you experience instability issues after removing the Intel Application Accelerator from a hard drive larger than 137GB, this may be because applications were previously installed in the upper 48-bit LBA region. If no other hard drive changes were made to any existing partitions, you should be able to reinstall the Intel Application Accelerator in order to correct these issues. After the Intel Application Accelerator is reinstalled, you should once again be able to access the data in the upper 48-bit LBA region.
