       BACKGROUND
       
       STACKER.INI
       
       MS-DOS 6 loads data compression utilities before it processes the
       CONFIG.SYS file. To take advantage of this, Stacker 3.1 uses the
       STACKER.INI file to provide configuration information.
       STACKER.INI replaces Stacker device driver lines in the
       CONFIG.SYS file used by other DOS versions. The switches and
       entries in STACKER.INI are similar to the format of Stacker 3.0.
       However, in STACKER.INI, each option is listed on a separate line
       instead of all being located on one Stacker device line. All
       Stacker 3.0 "/" options were left unchanged. New switches include
       /BD, /DIR, /I-, /Q-, /RP=, /SW=. Each switch should appear
       only once in the file. You can get more details from the User
       Guides, on-line Help, and README files.
       
       Except for those that are marked "New," the switches below have
       the same effects as they did in the Stacker 3.0 device driver's
       CONFIG.SYS command line.
       
       STACKER.COM Switch  Function
       /-AUTO  Disables Auto Mounting
       /BD=x NEW Base drive letter to start new Stacker drive letters
       /C=n  Sets cluster size to n (where n=4, 8, 16, 32)
       /DIR=<stacker path> NEW Path to STACKER directory
       /EMS  Loads buffers into Expanded Memory
       /I- NEW Turns off Command Interceptor
       /M=nn  Sets Stacker cache to nn (where nn = 1-64KB)
       /NB  No buffers
       /ND  No double buffers
       /NW  No Warning of
       /P=n     Sets compression tuning (where n=0 - 9)
       /Q- NEW Turns off quiet mode of Stacker driver at boot time
       
       
       STACKER.COM Switch (contd)  Function (contd)
       /RP=n NEW Reserve n replaceable drives, default=1
       /SW=jk mn ... NEW Swap drive j: with k:, m: with n:, etc.
       /UM  Loads buffers into UMB area (see 3.03 manual)
       
       
       The switches below have the same effect as they did in Stacker
       3.0's SSWAP.COM command line.
       
       SSWAP Switch  Function
       /W- Don't do default SPART.PAR search/update
       /W=<windows dir> Update SPART.PAR in windows dir
       /W+<windows dir> Do default search and update SPART.PAR in dir
       
       
       Multiple Swapping
       
       This multiple swap switch is rarely used because the ",SW" option
       (described in the General Syntax Rules that follow) on the
       STACVOL lines handles standard swapping. This switch appears at
       the top of the file, but swapping doesn't occur until all drives
       have been mounted. No more than 26 swaps are permitted.
       
       Multiple Swap Switch  Function
       /SW=jk mn xy After mounting all drives, swap drive pairs J: with
       K:, M: with N:, X: with Y:, etc.
       
       
       Other New Driver Switches
       
       Switch  Function
       /BD=x  Stacker will begin with drive letter x:, otherwise it will
       start at the next available drive
       (same as Stacker 3.0)
       /DIR=<stacker dir> Specifies where the Stacker directory is
       located. Setup uses this when installing an update
       
       
       Drive Specification Modifiers (Replaceable Drives)
       
        Switch  Function
       /RP=n The Stacker 3.0 replaceable drive syntax has been modified.
       The stand-alone "@" has been replaced with "/RP=n", where n
       indicates the number of replaceable drives to reserve.
       "@c:\stacvol.dsk" and standalone "c:" are replaced during Setup
       with "c:\stacvol.dsk,rp" by default.
       
       
       STACVOL Modifiers that specify mount method
       
       Three modifiers for STACVOL names specify the mount method. The
       modifiers are mandatory and follow the STACVOL name separated by
       a comma.( , ).
       
       Modifier  Mount Method
       RP Mount replaced
       SW Mount swapped, using next available drive letter
       NS Mount unswapped, using next available drive letter
       
       
       GENERAL SYNTAX RULES
       
        1.The "\" preceding the STACVOL name is optional.
        2.Whitespace (tab or space character) is allowed anywhere
            except within a defined word or specific name. Whitespace is
            allowed before or after an "=", but not after a "/".
        3.A line can have a maximum of one item, except for STACVOL
            line modifiers RP, SW, and NS (which are always the second
            item on a line). The /SW switch may have multiple arguments.
        4.None of the text is case-sensitive.
        5.Semicolon ( ; ) followed by a space indicates the start of a
            comment. At least one whitespace must appear before the
            semicolon unless it is at the beginning of a line.
        6.Maximum line length is 132 characters. Stacker Setup may
            truncate any excess when it modifies the file.
       Example
       
       This STACKER.INI file shows syntax variations. It is not
       necessarily consistent with itself, and normally is not this
       large.
       
       Syntax   Variation
       /dir=c:\stacker ; Specifies location of Stacker dir
       /ems ; Use expanded memory
       /rp=2 ; Reserve 2 replaceable drive letters
       /bd=i ; Begin assigning drive letters at I:
       /sw FM ; Swap drive F: with M: (after mounting)
       c:\stacvol.dsk,sw ; Swap, use next available for host drive
        ; A comment on a line by itself is allowed as are blank
       ; lines
       d:\stacvol.000,ns ; Don't swap, use next available drive letter
       * ; Reserve drive letter
       E:\stacvol.dsk,sw ; Mount drive E swapped
       F:\stacvol.000,ns ; Don't swap drive F (note that /sw option
       above will
       ; cause F: to swap with M: later)
       g:\stacvol.dsk,rp ; Mount drive g replaced
       
       
       EDITING STACKER.INI
       
       The STACKER.INI file is hidden, so direct editing can be awkward.
       A special filed, STACINI.BAT, is provided to make it easier. You
       have to specify the uncompressed boot drive when you use the
       STACINI.BAT file.
       
       To determine the uncompressed boot drive letter:
       
        1.At a DOS prompt, type:
                 STACKER <Enter>
        2.Examine the line that starts with Drive C:.
        3.The STACVOL file name at the end of this line includes the
            uncompressed drive letter (E:\STACVOL.DSK indicates drive
            E).
            
       To edit the STACKER.INI file:
       
        1.At a DOS prompt, type:
                      STACINI x:
        where x is the letter of the uncompressed boot drive.
        The file contains switches, followed by Stacker drive
            specifications. It looks something like this:
                            /P=1
                 /DIR=C:\STACKER
                           /RP=2
               C:\STACVOL.DSK,SW
               D:\STACVOL.DSK,SW
        2.Use the down arrow to place the cursor on the line you wish
            to edit. Then edit as usual.
        3.To insert a new line, place the cursor at the beginning of a
            line press ENTER.
        4.Type the switch on the blank line.
        5.Use <CTRL Z> to save the change and exit.
