CMD CSA-6520W PCI TO SCSI HOST ADAPTER
-------------------------------------
  If you have allowed the installer to install both the DOS and
  the Windows versions of the CMD fast disk and ASPI support,
  then you do not need to read this file.  This file is intended
  for user who wants to install the Windows Fast Disk Drivers
  manually.  

  Features:
  ---------
  Windows 3.1x/Windows for Workgroups 3.11 FastDisk Driver
  --------------------------------------------------------
  Loading the Windows FastDisk driver will yield faster
  Windows I/O throughput.  FastDisk is a true Windows Driver (VxD)
  which runs in protected mode and implements I/O queuing.  With
  FastDisk installed, you can open many more concurrent DOS boxes
  than without it (since it makes DOS boxes fully pageable), and
  Windows will speed up noticeably, especially if you like to open
  multiple windows running background tasks simultaneously.

  Installation of FastDisk is recommended only if your system has at
  least 2MB of memory.  If your system has less than 4MB of memory,
  you may want to tune FastDisk by editing your SYSTEM.INI file after
  install is done.  Find the line reading "CMDCCBCOUNT=200," and
  change it to 50.  See the FastDisk tuning section below for more
  information.

  NOTE:  FastDisk may be used only in ENHANCED MODE.  

  You should read the rest of this README file to get further
  information about this release before you do the installation.

  INSTALLING CSA-65XX WINDOWS FASTDISK DRIVER MANUALLY
  ----------------------------------------------------

  If CMD-65XX Fastdisk driver has been installed by CMD's install program,
  the SYSTEM.INI will have been updated automatically. Otherwise, users can
  update the SYSTEM.INI manually as below:

  1. Add the following lines to the [386Enh] section of your SYSTEM.INI

  device=CMDDISK.386
  device=INT13.386
  device=XPTSIM.386
  32BITDISKACCESS=ON
  CMDCCBCount=200
  CMDTimeoutCount=20000

  2. Uncomment the following line (if there is) by removing the semicolon
  at the beginning of the line or add the line just right before 
  device=*PAGEFILE (if there isn't already one)

  device=*BLOCKDEV

  3. Comment out the following lines (if there are any) by placing a 
  semicolon at the start of every line

  device=*int13
  device=*wdctrl
  device=ios.386
  device=vxdldr.386

  4. Now run Windows, open the Control Panel, and execute Enhanced.
  Make sure you have set up a permanent swapfile (or create one) to
  exercise the 32-bit disk access feature.  If you have Windows for
  Workgroups 3.11, turn on 32-bit file access feature and make sure
  the amount of RAM allocated for vcache.386 is 2 MB or more.

  5. You are ready to utilize both advanced features of Microsoft
  Windows/WFW 3.11:  32-bit disk access and 32-bit file access.


IMPORTANT INFORMATION
---------------------

  Upgrade/Installation of Microsoft Windows
  -----------------------------------------
  If, subsequent to running QuickSCSI Install, you decide to upgrade or
  reinstall Windows, the Windows installation program may re-enable the

     DEVICE=C:\WINDOWS\SMARTDRV.EXE /DOUBLE_BUFFER

  line in your CONFIG.SYS.  Since CSA-65XX BIOS fully supports VDS,
  double-buffering is not needed, and will unnecessarily degrade your
  performance.  To get rid of double-buffering, either edit your
  CONFIG.SYS and delete the offending line, or re-run QuickSCSI Install.


  Windows FastDisk Driver Tuning
  ------------------------------
  To reap the maximum performance benefits, it is recommended that
  you use a permanent Windows swap file.  The swap file is adjusted
  from the 386Enhanced icon in the Windows Control Panel.

  The I/O queue size is an entity which is configurable from the
  SYSTEM.INI file.  The I/O queue size is the maximum number I/O
  requests which may be outstanding at any given instant.  The default
  value is 200.  The queue size may be adjusted to any value greater
  than or equal to 50.  Each element in the queue will add an
  additional 140 bytes to non-pageable memory used by FastDisk.  To
  adjust the queue size, change the line which reads

     CMDCCBCOUNT=200

  to correspond to your desired queue size.  For systems which have
  4MB or less of RAM, you may want to adjust the value lower to free
  more memory for your applications.
