STACKER NOTE STACKER NOTE
STACKER CONFIGURATION
(Applies to Stacker for Windows & DOS 3.1 and MS-DOS 6)
STAC FAX 31014 (10/06/93)
_________________________________________________________________
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.
