  Connect your IDE drives to your CMD IDE controller.  Make sure that 
  the jumpers on the drives are set correctly for Master and Slave 
  drives.  If your CMD IDE controller is on an add-in card, plug it
  into a suitable Local Bus slot.

  Next, configure your CMOS with the proper drive types for the
  drive(s) connected to the IDE port.  If you are not sure
  of the drive type(s) and your BIOS does not auto-detect, you can
  use CheckIDE:

     1) Configure your CMOS for NO hard disks
     2) Boot your system with a floppy disk, and then replace the
	boot floppy with the QuickIDE floppy.
     3) Run "checkide" and make note of the drive geometry (heads,
	sectors,cylinders).
     4) Configure your CMOS user drive type and the geometry
	information from step (3).  Set the landing zone equal to
	the number of cylinders minus 1, and the write precompensation
	cylinder to 65535.

  Install the desired operating system that you are going to use on your 
  hard drive.
  
  Next, you must install the QuickIDE software.  For DOS, Windows/WFW 3.1x,
  and NetWare 3.1x, refer to the instructions below.  For other operating
  systems, refer to the appropriate README file, after reading GENERAL
  NOTES below.



  Installation for DOS, Windows/WFW 3.1x, and NetWare 3.1x
  --------------------------------------------------------

  To start QuickIDE installation, type 
  the path where your installation program resides.  For instance, 
  if you will be installing from drive A, type:

    A:INSTALL

  Once QuickIDE Installation loads, you will be guided through
  the installation process with a series of prompts and dialogs.
  If you have a mouse, be sure to load your mouse driver first.
  If you do not have a mouse, the keyboard will work fine.  The
  following key definitions may be helpful:

    ARROW KEYS - move within a field.
    TAB - move from one field to another within a window or dialog
   
  To select a button or menu, hold down ALT while pressing the
  underlined letter in the button or menu.

  After you have answered all the questions, QuickIDE will copy
  files to your C: drive and perform edits to files as needed.
  Backup copies of any files it changes will be created in case you
  want to undo the installation.  The files which may be modified are:
  CONFIG.SYS and  AUTOEXEC.BAT.  The original files will be renamed to
  CONFIG.000, etc.



GENERAL NOTES
-------------

  Some IDE drives have firmware bugs which cause them to declare
  themselves as Mode 2 drives even though they are really slower.
  As a result, the following exception table has been implemented in
  all CMD drivers:

      1. Samsung Mode 2 drives are slowed down to Mode 1.
      2. Maxtor Mode 2 drives are slowed down to Mode 1.
      3. Quantum Mode 2 drives are slowed down to Mode 0.

      If you have a drive with a similar bug not listed above, refer to
      the following command line switches:
      1) DOS: CMD640X.SYS - /O - documented in README.DOS
      2) OS/2: CMD640X.ADD - /PIOMODE:d - documented in README.OS2 or
	 README.OS3
      3) NT: see README.N31 or README.N35 - ATA PIO Mode Timing Overrides
