*DEFAULT VERSUS CUSTOM HELP

The following are the two different ways to configure the IDE-32000 
VL controller:

   Custom Configuration

     This option allows the user to selectively make changes to the
     controller's configuration.  Changes may be made on such items
     as Serial Ports, Parallel Ports, Floppy Controller, Second IDE
     Channel, VL Bus Speed and Width, etc.  It also allows the user  
     to select the operating mode of devices attached to the Primary
     Channel. This includes selecting the device's PIO Mode, enabling
     Read/Write Multiple for performance improvement and drive
     Addressing Mode.

   Factory Default Configuration

     This option configures the VL controller to its factory default
     settings.  Refer to the (TBD) for more information.


*CUSTOM CONFIG HELP

Custom Configuration

The following explains the different setting options for the
IDE-32000 VL controller:


   Factory Default Message

     If this checkbox is selected, the BIOS upon boot-up time will
     display a message letting the user press a key to use the factory
     default settings for the software configurable options on the
     IDE-32000. Refer to the controller's Installation Guide for
     description of the factory default values.

   Floppy Controller Message

     If this checkbox is selected, the BIOS upon boot-up time will
     display a message letting the user press a key to enable or disable
     the floppy controller on the IDE-32000.

   VL Bus Speed

     This sets the VL bus speed that the IDE-32000  controller is 
     running at. Default value is 33 MHz. Other speeds are also 
     available at 25, 40, 50 MHz.
     The 33MHz is the default mode. However, if the VL bus on the 
     computer can operate at higher value, this will increase performance. 
     Refer to your System Guide for more details.

   VL Bus Width

     Select the bandwidth of the VL bus. Default value is 32-bit. The
     other option is 16 bit. The 32-bit mode gives the optimal
     performance. The 16-bit mode is available if any problem are seen
     with a particular peripheral and/or system.

   Device 0 (Master) Configure

     Select the "Configure..." button to specify the operating mode for
     the Master (Drive 0) device.

   Device 1 (Slave) Configure

     Select the "Configure..." button to specify the operating mode for
     the Slave (Drive 1) device.

   Second IDE Channel

     If this checkbox is selected, the secondary IDE channel is enabled.

   Floppy Controller

     Configure the floppy controller as the Primary Floppy
     Controller, Secondary Floppy Controller or Disabled.  Choose
     primary if the system motherboard does not have a floppy 
     controller.  Choose Secondary if the IDE-32000 will serve as 
     a supplemental floppy controller for the system. Choose Disabled
     if no floppy support is required.


   Serial Port Settings

     This indicates the settings for the two (2) serial ports on the
     IDE-32000. A list is provided with all combinations for the two
     serial ports.

   Parallel Port Address

     This indicates the address for the parallel port. A list is provided
     with all available options for the parallel port address.

   Parallel Port Mode

     This indicates the operating mode of the parallel port. Valid
     mode settings are as follows:

        Standard Parallel Port or Printer Mode (SPP)
        Extended Parallel Port (EPP)
        Enhanced Capabilities with SPP (ECP)
        Enhanced Capabilties with EPP (ECP & EPP)
        
*ATA DRIVE CONFIG HELP

ATA Drive Configuration

This screen shows information returned from the identify drive command.  
The following information is provided:

    - Drive Model 
    - Drive Firmware
    - Drive Capacity in MegaBytes(Mb)
    - Drive physical number of cylinders, heads and sectors.

It also indicates if the drive is capable of 

    - LBA (Logical Block Address) addressing mode
    - Advanced PIO Mode (Modes 3 and up)
    - Read/Write Multiple commands and if it does, what is 
      the maximum sector size it can support.

The following three options are programmable for ATA fixed disk on 
the IDE-32000 controller:

   PIO Data Transfer Mode

     This refers to the data transfer mode of the drive.  Typical IDE
     devices normally operates at PIO Mode 0 (3 Mb/sec) only.  
     Enhanced IDE devices have improved the data transfer rates and
     can operate from Mode 0 to Mode 3 (11 Mb/sec).  If the ATA
     device can be programmed to a mode higher than 0, the available 
     mode options are provided for the user to select. The device
     specifies which maximum mode it can support in the field 
     "Advanced PIO Mode". Some drives may report that they support a 
     higher PIO mode but does not perform as reported.  These kind of 
     drives may cause data integrity problems. Therefore, it is 
     recommended that data is properly backed up before programming 
     a drive for a PIO mode higher than mode 0.

   Read/Write Multiple Support

     Some enhanced IDE drives can support multiple sectors read and
     write operations.  This feature significantly improves drive 
     performance and may either be enabled or disabled by the user.

   Drive Addressing Mode

     Typical IDE devices have always used a Cylinder-Head-Sector (CHS)
     addressing scheme to access the data on the drive.  With the
     introduciton of enhanced IDE drives, the Logical Block Addressing
     (LBA) scheme can also be support.  Choose the addressing mode 
     that works best for the drive.  The default is CHS. 


*ATAPI DRIVE CONFIG HELP

ATAPI Drive Configuration

This screen shows information returned from the identify drive command.  
The following information is provided:

    - Drive Manufacturer
    - Drive Model
    - Drive Firmware

It also indicates if the drive is capable of 

    - Advanced PIO Mode (Modes 3 and up)

The programmable option for ATAPI device on the IDE-32000 controller is:

   PIO Data Transfer Mode

     This refers to the data transfer mode of the drive.  Typical ATAPI
     devices normally operates at PIO Mode 0 (3 Mb/sec) only.  
     Enhanced ATAPI devices have improved the data transfer rates and
     can operate from Mode 0 to Mode 3 (11 Mb/sec).  If the ATAPI
     device can be programmed to a mode higher than mode 0, the available 
     mode options are provided for the user to select. The device
     specifies which maximum mode it can support in the field 
     "Advanced PIO Mode". Some drives may report that they support a 
     higher PIO mode but does not perform as reported.  These kind of 
     drives may cause data integrity problems. Therefore, it is 
     recommended that data is properly backed up before programming 
     a drive for a PIO mode higher than mode 0.
