*************************** SDMS NWPA Drivers ***************************

The SDMS NWPA drivers for the Novell NetWare operating system allow 
you to utilize various LSI Logic SCSI controllers or processors. The
SDMS SCSI BIOS (version 4.19) controls these controllers or processors
with NetWare. The NWPA drivers along with the designated LSI Logic SCSI
controllers or processors and an appropriate Custom Device Module (CDM)
provide a SCSI solution within the NetWare environment.

LSI Logic provides a single driver for the Novell NetWare versions 4.XX and
5.XX environments, which is dependent upon the chip set. This document explains
how to install and use the LSI Logic NWPA SCSI Host Adapter Module (HAM)
drivers for NetWare.

NOTE: Current NetWare NWPA drivers can be downloaded from the LSI Logic 
      Web site at http://www.lsilogic.com. After you are connected to this 
      Web site, place your cursor on the Get Drivers option in the menu bar. 
      Click on the Drivers selection. Choose the Novell NetWare operating 
      system for SCSI from the list. Click on the Go button. Follow the
      instructions on subsequent screens to download the drivers.

*  *  *  *  *  *  *  *  *  * LSI Logic Devices Supported *  *  *  *  *  *  *  *  *

All LSI Logic devices and host adapters have undergone a name change. 
They have transitioned from a SYM prefix to an LSI prefix. This name change
also affects the drivers for NetWare.

The LSI8XXNW.HAM supports the following devices and their associated LSI Logic
host adapters:

o  LSI53C810, LSI53C810A, LSI53C810AE (LSI8100S, LSI8100ASP, LSI20810)
o  LSI53C815 (LSI815XS, LSI8150SP)
o  LSI53C825, LSI53C825A (LSI8250S, LSI8251S, LSI8251D, LSI8250ASP, LSI8251ASP,
   LSI8251AD)
o  LSI53C860, LSI53C860AE (LSI8600SP, LSI20860)
o  LSI53C875, LSI53C875E (LSI8750SP, LSI8751SP, LSI8751SPE, LSI8751D)

o  LSI53C885 
o  LSI53C895  (LSI8951U, LSI8952U)

The LSIHINW.HAM supports the following device and associated LSI Logic host 
adapters:

o LSI53C895A (LSI8953U)
o LSI53C896  (LSI22910, LSI21002, LSI22902)

The LSI_U3NW.HAM supports the following device and associated LSI Logic host 
adapters:

o LSI53C1000 (LSI20160, LSI20160L)
o LSI53C1010 (LSI22915A, LSI21040, LSI22903, LSI20903, LSI21003)

*  *  *  *  *  *  *  *  *  *  * Description  *  *  *  *  *  *  *  *  *  * 

The SDMS NWPA solution consists of the device drivers, LSI8XXNW.HAM,
LSIHINW.HAM, LSI_U3NW.HAM and the NetWare NWPA installation files
LSI8XXNW.DDI, LSIHINW.DDI, LSI_U3NW.DDI.

LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM are NWPA Host Adapter Modules
(HAMs). In order to support SCSI devices, you must load the HAM module in
conjunction with a SCSI Custom Device Module (CDM). Novell has developed
generic CDMs to support SCSI Hard Drives, SCSI CD-ROM devices, SCSI Magneto
Optical devices, SCSI tape devices, and SCSI changer devices. In addition,
third party vendors are developing CDMs to support their specific devices. 


*  *  *  *  *  *  *  *  *  *  * ASPI Support  *  *  *  *  *  *  *  *  *  * 

NWPA ASPI support is provided by using NetWare's NWASPI driver. NetWare, or
third party applications, may use this interface to communicate with a SCSI
device attached to an LSI Logic controller, including SCSI-2 tape devices 
using NWTAPE.CDM.


******************** Installing Your NWPA NetWare Drivers ******************* 

Install NetWare as described in the Novell NetWare Installation Manual. The 
following information is provided to assist in the installation.

The SDMS NWPA NetWare driver must be loaded once for each LSI Logic controller
SCSI channel present in the system.


*  *  *  *  *  *  *  Preparing Your System for NWPA Drivers  *  *  *  *  *  * 

The SDMS NWPA drivers, LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM support the
following DOS drivers:

     o  ASPI8XX.SYS  (Version 4.11 or greater)  
     o  SYMCD.SYS   
     o  SYMDISK.SYS  
 
These drivers do not support the older SDMS 3.XX DOS drivers (DOSCAM.SYS, 
MINICAM.SYS, CDROM.SYS, and SCSIDISK.SYS).

The BIOS version 4.19 is the minimum SDMS BIOS required for NetWare 
without ASPI8XX.SYS (version 4.11 or greater).

Please see the section titled "When using the 4.XX BIOS" regarding 8XX_32.ROM
with SCAM enabled before upgrading the BIOS.

To Upgrade the BIOS (boot ROM) from 3.XX,4.XX to 4.19:

1. Load the FLASH8X5.EXE program.

2. Select the appropriate BIOS file (that is, 8XX_64.ROM). You must 
   use BIOS version 4.19 if not using the ASPI8XX.SYS driver. 

To Check the Status of DOS drivers: 

1. Edit the CONFIG.SYS file. 

2. If any of the following lines appear, you may remove or delete these lines.
   LSI Logic recommends using the REM command to comment them out in case these
   lines are needed later.
    
     DEVICE=<path>\DOSCAM.SYS    
     DEVICE=<path>\MINICAM.SYS    
     DEVICE=<path>\CDROM.SYS /d:<name>    
     DEVICE=<path>\SCSIDISK.SYS
     DEVICE=<path>\HIMEM.SYS
     DEVICE=<path>\EMM386.SYS    

3. If CD-ROM support is required, then add the following: 
   
     DEVICE=<path>\ASPI8XX.SYS    
     DEVICE=<path>\SYMCD.SYS /d:<name>   

4.  Add the following line to the AUTOEXEC.BAT file:
     
      DEVICE=<path>\mscdex /d:<name> 

Note: The /d: is not a drive letter designation; it indicates the name you
      wish assigned to your CD-ROM. You must include the NAME, which can
      use any combination of up to 8 characters.

*  *  *  *  *  *  *  *  * NetWare 5.xx New Installations  *  *  *  *  *  * 

1. Begin the file server installation according to the instructions in the 
   file server installation chapter in the Novell NetWare Installation 
   Manual.

2. Insert the SDMS device drivers diskette into drive A: or B: when the
   NetWare installation procedure prompts you for a driver disk, 

3. Press the INS key twice to select an unlisted driver. 
   A dialog box appears.
  
   If the driver diskette is in the A: drive, press Enter to continue. 
   If the driver diskette is in the B: drive, press F3 (to specify the 
   path to search for the driver), and enter the drive letter: 

    B:
    
   and press Enter.

   The LSI8XXNW.HAM, LSIHINW.HAM, or the LSI_U3NW.HAM driver will appear as
   a selection.

   The system prompts you with limited available command line options for
   loading the driver. A description of each option appears in the box at the
   bottom of the installation screen. Refer to the Command Line Options section
   for more information. Modify any option values as needed for this
   installation.

4. Follow the prompts to complete this installation.

   The HAM driver(s) are loaded for each LSI Logic controller SCSI channel from
   the first LOAD statement to the last LOAD statement.

*  *  *  *  *  *  *  *  * NetWare 4.xx New Installations  *  *  *  *  *  * 

1. Begin the file server installation according to the instructions in the 
   file server installation chapter in the Novell NetWare Installation 
   Manual.

2. Insert the SDMS device drivers diskette into drive A: or B: when the
   NetWare installation procedure prompts you for a driver disk, 

3. Press the INS key twice to select an unlisted driver.

   and press Enter.

   The LSI8XXNW.HAM, LSIHINW.HAM, or the LSI_U3NW.HAM driver will appear as
   a selection.
     
   The system prompts the user with limited available command line options
   for loading the driver. A description of each option appears in the box at
   the bottom of the installation screen. Refer to the Command Line Options
   section for more information. Modify any option values as needed for this
   installation.

4. Load a separate instance of the driver for every LSI Logic controller SCSI 
   channel or host adapter present in the system.

5. Accept the slot numbers displayed when prompted for a slot number.
   Make sure to write these slot numbers down for future reference.

6. a. When asked to edit the STARTUP.NCF file, make sure the LSI8XXNW.HAM (or 
      LSIHINW.HAM or LSI_U3NW.HAM) is loaded once per LSI Logic controller SCSI 
      channel present in the system.
   b. Add the statement SLOT=<slot number> to each load line in the STARTUP.NCF,
      by specifying the slot numbers written down in step 6 above, with only one
      slot number per load instance.

      The HAM driver(s) are loaded for each LSI Logic controller SCSI channel from
      the first LOAD statement to the last LOAD statement.


*  *  *  *  *  *  *  * NetWare 4.xx SFT-III Installations  *  *  *  *  *  * 

1. Install your primary server following procedures for the native 4.11 
   installation.

2. Begin the SFT-III installation as instructed by NetWare installation 
   procedures.

3. While installing the secondary server, you have the option of copying the 
   LSI8XXNW.HAM driver from the primary server. Press F10 to accept. 



*  *  *  *  *  *  *  *  * Reconfiguring Driver Options  *  *  *  *  *  *  *   

To reconfigure driver options, follow these steps: 

1. To unload all instances of the driver, type: 

     unload LSI8XXNW.HAM

     -or-

     unload LSIHINW.HAM

     -or-

     unload LSI_U3NW.HAM

2. To reload each instance of the driver with the desired option settings, 
   type: 

     load LSI8XXNW.HAM slot=<slot number> <options>

     -or-

     load LSIHINW.HAM slot=<slot number> <options>

     -or-

     load LSI_U3NW.HAM slot=<slot number> <options>

3. If the changes made to the load options of one or more load instance are 
   permanent, and the driver is loaded automatically at server boot time, you 
   must specify these options in the STARTUP.NCF or AUTOEXEC.NCF file. 


*************************** Command Line Options **************************** 

The LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM drivers have many tuning
options. A list of tuning options is available below that include the default
option along with a list of valid options. Each option has a description of
when to use it, the syntax used, and any impact its use may have on the
system.

If an option is specified but the assignment is not valid, then the default 
value is used. Use the options described below by placing the specified 
characters on the load command line for the NWPA driver. For example, if the 
Wide SCSI Option on the command line is desired, the load command line should
look like this: 

     load LSI8XXNW.HAM wide=off

     -or-

     load LSIHINW.HAM wide=off

     -or-

     load LSI_U3NW.HAM wide=off

Note: No spaces are allowed within a specific command line option, but spaces 
      are required between different command line options. 


*  *  *  *  *  *  *  *  *  *  * Information Option *  *  *  *  *  *  *  *  * 

The information option described below is: Using the Help Mode Option. 

*   *   * Using the Help Mode Option *   *   * 

     Syntax: ? or h

     Function: Display the options available in the driver.

     Possible Impact: The driver will not load with ? or h specified.

     This option is specified on the command line for a brief description of 
     each of the options available in the driver, as well as valid values for 
     each option. If the ? or h option is specified along with other 
     options, the help screen is invoked, the other options are ignored, and 
     the driver is not loaded. 


*  *  *  *  *  *  NetWare NWPA Driver Customizable Options  *  *  *  *  *  * 

Each command may be preceeded by a "/" or "-" for backwards compatibility at
the discretion of the user.

The line options with multiple names are simply aliases for the same command.
For example, to specify a SCSI bus host identification value, you could use
one of these three aliases:

HostScsiId
HostId
Hid  

In this case, "hostscsiid", "hostid", and "hid" all specify the same option 
for the selection of the host adapter id.

The alpha-case does not matter, so you can intermix upper and lower case in
any way.


*   *   * Using the Autosense Option *   *   *

     Syntax: autosense=<option>[targetIDlist]
             or
             asense=<option>[targetIDlist]

     Default value: on

     Valid options: on  = autosense is enabled
                    off = autosense is disabled
     
     Function: Enables sense data to be returned automatically for the 
               specified target

     This option allows you to disable sense data if third party drivers do
     not support the auto sense feature of the LSI Logic host adapters.

   
*   *   * Using the Domain Validation Option *   *   *

     Syntax: domainvalidation=<option>[targetIDlist]
             or
             dv=<option>[targetIDlist]

     Default value: on

     Valid options: on     = Domain validation enabled
                    off    = All domain validation disabled
                    nowidth= No domain validation for width settings
                    nowrrd = Do not perform read/write cycle.
                    noread = Do not perform media read.
                    

     Function: Control domain validation options for the Target ID.
     
    This option is a software procedure in which a host queries a device
    to determine its ability to communicate at the negotiated width and
    sync rates. Domain Validation is performed at system boot time to test
    the data integrity of the SCSI bus between the host adapter and each target
    device. Note that some older SCSI devices do not support Domain Validation
    operations.


*   *   * Using the Elevator Threshold Option *   *   *

     Syntax: elev=<option>[targetIDlist]

     Default value: 4

     Valid options: 0-250 (0=disable)

     Function: Specify the maximum number of I/Os the HAM should queue before 
     allowing NWPA to filter and organize requests.

     NWPA uses elevator queues to determine how many I/Os are queued to the HAM
     before organizing requests and generating scatter gather lists. 
     If this number is set too low, then adapter I/O starvation may result. 
     If the number is too high, then sorting of I/Os and/or generation of 
     scatter gather lists may not occur. Varying the elevator threshold value
     may affect performance.


*   *   * Using the Handles Option *   *   *

     Syntax: handles=<option>[targetIDlist] or
             handle =<option>[targetIDlist] or
             hdl=<option>[targetIDlist]

     Default value: 300 handles

     Valid options: Number of handles

     Function: Defines the maximum number of bus/device/target handles

     Larger configurations should increase this value to the total number
     of bus/target/device(s) in a system.


*   *   * Using the Host SCSI ID Option *   *   *

     Syntax: HostScsiId=<option>[targetIDlist] or   
             HostId=<option>[targetIDlist] or
             hid=<option>[targetIDlist]

     Default value: 7

     Valid options: Can range between 0 - 7 for narrow bus
                    or
                    between 0 - 15 for wide bus

     Function: Indicates the SCSI identifier of an adapter

     LSI Logic recommends that the Host SCSI ID be set to 7.


*   *   * Using the LUN Option *   *   *

     Syntax: /lun

     Default value: off

     Function: Enables NWPA scan for Logical Unit Numbers (LUNs).

     
*   *   * Using the Minimum Timeout Option *   *   *

     Syntax: mintimeout=<option>[targetIDlist] or
             mint=<option>[targetIDlist] 
                        
     Default value: 0 (a value of zero disables this feature)

     Valid options: 0-1200

     Function: Specifies the minimum device timeout in seconds.

     This option uses a timeout mechanism to support particularly slow
     devices. When a driver issues a command to a SCSI device, a timer
     is started. If the timer expires before the command completes, the
     driver assumes something has gone wrong and takes steps to recover.
     The minimum setting is 0, which is no timeout. 


*   *   * Using the Negotiation Option *   *   *

     Syntax: negotiation=<option>[targetIDlist]
             or
             neg=<option>[targetIDlist]
  
     Default value: none

     Valid options: on       = All negotiations on
                    off      = Negotiation off
                    ppir     = All negotiation on
                    sync     = Synchronous negotiation only
                    wide     = Width negotiation only
                    syncwide = Sync and width negotiation only
                    twostep  = Sync and width negotiation only, one per I/O
                    threestep= Sync, width and ppir negotiation, one per I/O
     
     Function: Enable synchronous, wide, or ppir negotiation with the target ID.
               
     This option allows you to enable/disable all negotiations or just
     synchronous or width negotiations with the target ID.


*   *   * Using the No Negotiation Option *   *   *

     Syntax: noneg=<targetID>
  
     Default value: none

     Valid options: Any valid device ID betweeen 0 to 15

     Function: Do not negotiate synchronous or wide settings to the
               Target ID.

     Possible Impact: Device will always operate in asynchronous and narrow mode.
 
     Initially during the scanning phase, the driver begins by negotiating
     asynchronous and narrow mode settings with each device found. Once target
     communication is established, the desired synchronous and wide settings are
     renegotiated. However, some devices have a problem with the initial negotiation
     such as the new SAF-TE chip from another vendor, and older or non-standard,
     non-INT13h devices.

*   *   * Using the Parity Option *   *   *

     Syntax: parity=<option>[targetIDlist]
             or
             ecc=<option>[targetIDlist]

     Default value: on

     Valid options: on     = parity/error checking is enabled
                    off    = parity/error checking is disabled
                    parity = bus parity is enabled (without error checking)
                    ecc    = parity/error checking is enabled
     
     Function: Controls parity/error checking for the specified target ID(s).

     This option allows you to enable/disable the SCSI bus data integrity 
     checking feature known as parity. Some SCSI devices do not generate
     parity in which case this option allows disabling this feature.


*   *   * Using the Read Capacity Option *   *   *

     Syntax: readcap=<option>[targetIDlist]
             or
             rc=<option>[targetIDlist]

     Default value: on

     Valid options: on  = read capacity is enabled
                    off = read capacity is disabled
     
     Function: Enables a read capacity command during initial scan to
               the target ID(s).

     This option allows you to disable issuing the read capacity command
     during an initial scan to the target ID(s).


*   *   * Using the Scan Option *   *   *

     Syntax: scan=<option>[targetIDlist][lunIDlist]    
                          
     Default value: list

     Valid options: on, off, list, or order

     Function: Specifies the Logical Unit Uumbers (LUNs) to scan.
               
     This option allows you to change the default for scanning LUNs per
     target ID on the SCSI bus.


*   *   * Using the Slot Option *   *   *

    Syntax: slot=<option>[targetIDlist]

    Default value: None

    Valid options: 0-10099

    Function: Specify the slot instance number of the LSI Logic  
    controller to which the load instance applies.

    The slot option specifies the LSI Logic controller SCSI channel (embedded
    chip or host adapter) that pertains to the current load. This information
    is required to load the driver. If this information is not specified on the 
    load line, the driver will prompt for the slot number. 


*   *   * Using the Spin Up Option *   *   *

     Syntax: spinup=<option>[targetIDlist]
             or
             spin=<option>[targetIDlist]

     Default value: on

     Valid options: on  = spin up is enabled
                    off = spin up is disabled
     
     Function: Enables spin up command during initial scan. 

     This option allows you to disable issuing a spin up command during
     an initial scan to the specified target ID(s).


*   *   * Using the Synchronous SCSI Option *   *   *

     Syntax: synchronous=<option>[targetIDlist] or
             sync=<option>[targetIDlist] or
             syn=<option>[targetIDlist]

     Default value: Maximum of the HAB/HBA
     
     Examples of rate specifier are:

     0 MB or 10 MB (mega bytes per second)
     20 MT or 40 MT (mega transfers per second) 

     Valid options: 0 MB = asynchronous
                    0 MT = asynchronous
                    5 MB =  5 MB
                    5 MT =  5 MB (8 bit) or 10 MB (16 bit)
                   10 MB = 10 MB
                   10 MT = 10 MB (8 bit) or 20 MB (16 bit)
                   20 MB = 20 MB
                   20 MT = 20 MB (8 bit) or 40 MB (16 bit)
                   33 MB = 33.3 MB
                   33 MT = 33.3 MB (8 bit) or 66.6 MB (16 bit)
                   40 MB = 40 MB
                   40 MT = 40 MB (8 bit) or 80 MB (16 bit)
                   80 MB = 80 MB
                   80 MT = 80 MB (8 bit) or 160 MB (16 bit)
   
     Function: Set synchronous transfer rate for specified target(s).

     Possible Impact: Could cause a device to operate slower than
                      its maximum speed.

     This synchronous SCSI option allows you to enable/disable support of Fast, 
     Ultra, Ultra2 and Ultra160 SCSI synchronous data transfers when using a
     Fast, Ultra, Ultra2, or Ultra160 SCSI controller. Synchronous data transfers 
     increase the I/O performance of a system. 


*   *   * Using the Tagged Queuing Option *   *   * 

     Syntax: qtags=<option>[targetIDlist]

     Default value: on

     Valid options: on, off

     Function: Enable/disable use of simple/ordered tagged command queueing.

     Enabling the qtags option causes the driver to issue tagged I/O requests 
     to the devices that support tagged queuing. Devices that do not support 
     tagged queuing are not issued tagged requests. Depending on the drive 
     controller, use of queue tags increases throughput of the device.
     However, the optimal number of queue tags is based on the specific 
     device type.  Tagged queuing may result in improved I/O throughput in  
     devices that support such an option.

*   *   * Using the Test Unit Ready Option *   *   *

     Syntax: testready=<option>[targetIDlist]
             or
             tur=<option>[targetIDlist]

     Default value: on

     Valid options: on  = test unit ready is enabled
                    off = test unit ready is disabled
     
     Function: Issues a test to ensure unit is ready during initial
               scan.

     This option allows you to disable issuing a test unit ready during
     the initial scan to the specified target ID(s).


*   *   * Using the Verbose Option *   *   *

     Syntax: verbose=<option>[targetIDlist]

     Default value: off

     Valid options: on, off

     Function: Displays more detailed information on options and DOS
               configuration.

     This option is useful when multiple adapters are present in the system,
     and the PCI Device ID, the PCI Bus number, and the PCI Device/Function
     number for each adapter needs to be known. 


*   *   * Using the Width Option *   *   *

     Syntax: width=<option>[targetIDlist or
             wide=<option>[targetIDlist] or
             wid=<option>[targetIDlist]

     Default value: on

     Valid options: narrow =  8 bit data bus
                    wide   = 16 bit data bus
                    off    =  8 bit data bus
                    on     = 16 bit data bus
                    8      =  8 bit data bus
                    16     = 16 bit data bus

     Function: Set bus width negotiations for specified targets.

     This option allows you to disable support of wide SCSI when using a
     a wide SCSI controller. Set this option to "narrow", "off", or "8"
     to disable a wide SCSI device when an 8-bit SCSI cable is connected
     somewhere on the bus between the wide SCSI host adapter and the wide
     device. This type of connection prohibits the transfer of wide data.
     If this option is set to  "narrow", "off", or "8", the wide device still
     works, but all data transferred to or from the device is narrow (8 bit).
     The driver does not initiate a wide SCSI transfer request negotiation.
     Alternatively, to enable support of wide SCSI when it no longer needs
     to be disabled, set this option to "wide", "on", or "16".


********************* Important Additional Information ********************** 

*  *  *  *  * For Information Pertaining to a Specific Driver *  *  *  *  * 

This document addresses options available on the SDMS NWPA NetWare driver,
versions 4.02.00 or later. For information pertaining to a specific driver, 
please do one of the following:

1. For NetWare version 4.11, consult the *.DDI file for options available
   for the LSI Logic HAM driver. This is accessed by using the NetWare Install
   utility.
   
   or

2. Load the driver specifying the ? option on the command line of the 
   LSI Logic HAM driver. The driver does not actually load, but available options
   are displayed.


*  *  *  *  *  *  *  *  *  * DOS Access Dependencies *  *  *  *  *  *  *  *  

Typically, NetWare requires access to the DOS partition (perhaps to load a 
file, or to down the system). The LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3.SYS
drivers support several SDMS DOS configurations.

The LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM drivers detect whether an 
SDMS 4.XX BIOS is present. They also detect if the SDMS ASPI8XX.SYS 4.11 DOS 
driver is loaded. The minimum required BIOS version is SDMS 4.19 without 
ASPI8XX.SYS <version 4.11>.

Note: LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM drivers do not support the 
      SDMS 3.XX DOS drivers--DOSCAM and MINICAM.

*  *  *  *  *  *  *  *  * Supported DOS Configurations *  *  *  *  *  *  *  * 

The DOS configurations supported by the HAM drivers are:

     SDMS 4.19 or greater BIOS without ASPI8XX.SYS
     SDMS 4.19 or older BIOS with ASPI8XX.SYS  
     No SDMS BIOS, ASPI8XX.SYS*  

*In addition to ASPI8XX.SYS (version 4.11 or greater), SYMCD.SYS and/or 
 SYMDISK.SYS may be optionally loaded for DOS CD-ROM and DOS Magneto Optical (MO)
 support. SYMCD.SYS and SYMDISK.SYS are NOT required for CD-ROM or MO support
 under NetWare. 

*  *  *  *  *  *  *  *  *  * When Using the 4.XX BIOS *  *  *  *  *  *  *  * 
 
If an older BIOS is present, load ASPI8XX.SYS (version 4.11 or greater) in the
CONFIG.SYS file.  LSI Logic recommends updating the BIOS to SDMS 4.19. SCAM
must be disabled in the 4.XX BIOS. If SCAM is enabled, then the SDMS NWPA
driver will not load.


*  *  *  *  *  *  *  *  *  * When Using ASPI8XX.SYS *  *  *  *  *  *  *  *  * 

SCAM support defaults to off in ASPI Manager version 4.11 and later.  


*   *   * Supported DOS Drivers *   *   *

The SDMS ASPI8XX.SYS (version 4.11 or greater> DOS driver supports the SDMS 4.19
or older BIOS. SYMCD.SYS and SYMDISK.SYS provide support for CD-ROM and MO devices
under DOS. Neither SYMCD.SYS nor SYMDISK.SYS are required for NetWare support of
CD-ROM and MO devices. For SCSI CD-ROM installation, ASPI8XX.SYS and SYMCD.SYS
are required.

The SDMS NWPA drivers, LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM, support
the list of DOS drivers described below.

*    * ASPI8XX.SYS *    *

The ASPI8XX.SYS driver provides an ASPI layer interface for disk and non-disk
devices. ASPI8XX.SYS is required for NetWare support if the SDMS 3.XX BIOS or 
SDMS 4.19 or older BIOS are used. If NetWare is being installed from a
SCSI CD-ROM device on a LSI Logic controller, SYMCD.SYS is required with
ASPI8XX.SYS.

*    * SYMCD.SYS *    *

To install the NetWare operating system from CD-ROM, load the SYMCD.SYS driver
with ASPI8XX.SYS. Once the NetWare operating system installation has completed, 
SYMCD.SYS is not needed. The NetWare NWPA environment provides support for 
SCSI CD-ROMs through the NetWare driver interface. 

*    * MSCDEX.EXE *    *

The MSCDEX.EXE driver (provided with DOS) is required in conjunction with 
SYMCD.SYS to install NetWare from a CD-ROM. 

*    * SYMDISK.SYS *    *

The SYMDISK.SYS driver provides support for removable media and large sector
size devices under DOS. This driver is not required for NetWare support of 
these devices.

Note: The NetWare drivers can function independently of any DOS drivers, with 
      the following exceptions:

     1. The installation of NetWare is from a SCSI CD-ROM.
        
     2. The unsupported SDMS 3.XX BIOS or supported SDMS 4.19 or older 
        BIOS are being used. 

*  *  *  *  *  *  *  *  *  * When Using No SDMS BIOS *  *  *  *  *  *  *  * 

The LSI8XXNW.HAM, LSIHINW.HAM, and LSI_U3NW.HAM drivers operate properly on a
system when no SDMS BIOS or SDMS DOS drivers are present. In this case, DOS
must reside on a device that is not connected to a LSI Logic controller-based
host adapter. As an example, DOS could reside on an IDE drive.
