Installing CompuShow
====================
If you received CompuShow on a floppy disk, install it as described below and
set the original floppy aside (don't run ANY SOFTWARE on an original "master
disk"; install it on a hard disk or a "working copy floppy disk", first.) If
you downloaded CompuShow using a modem, copy the downloaded file to a backup
floppy before proceeding.
After installing CompuShow, we recommend that you print all the documentation
on your printer. You should either have README.BAT or README.EXE included
with the CompuShow program. At your DOS prompt, type "README" and press
carriage return (or ENTER).
Installing on a floppy disk
---------------------------
Install CompuShow on a floppy disk by copying the CompuShow files to a
formatted disk (for example, "COPY A:*.* B:" will copy all files from a disk
in drive A: to a disk in drive B:).
Installing on a hard disk
-------------------------
Install CompuShow on a hard disk by placing the files in a separate hard disk
sub-directory. For example, to place CompuShow on hard disk drive C:
C:
MD CSHOW
CD CSHOW
COPY A:*.*
Compressing CSHOW.EXE
---------------------
The CompuShow program(s) have been compressed using PkLite. Do not attempt to
compress them again using PkLite, LzExe or a similar utility.
Executing CompuShow
-------------------
In order to be able to execute CompuShow "from anywhere" you can do one of
two things:
1) add "C:\CSHOW" to the "PATH" statement in AUTOEXEC.BAT
2) use a batch file (on the path) to execute CompuShow.
We recommend the SECOND method, so create a batch file in a sub-directory
that's already included in the path statement of AUTOEXEC.BAT. For example,
at your DOS prompt, execute the PATH command without any parameters to find
out what the current setting is:
PATH <-- you type this
PATH=C:\PROGRAMS;C:\BATS;C:\DOS <-- DOS responds
[SETUP.DOC] Page 1
Select an appropriate sub-directory (such as C:\BATS) and create a batch file
to execute CompuShow. (You may also want to put one or more of the start-up
options, listed below, in the batch file):
(DOS version 5 includes a text editor)
EDIT C:\BATS\CSHOW.BAT
type in:
C:\CSHOW\CSHOW %1 %2 %3 %4 %5 %6 %7 %8 %9
then Alt-F X Y (to exit the edit progam and save the file)
(DOS version 3 and above):
C:
CD \BATS
COPY CON CSHOW.BAT
C:\CSHOW\CSHOW %1 %2 %3 %4 %5 %6 %7 %8 %9^Z
(DOS below version 3):
C:
CD \BATS
COPY CON CSHOW.BAT
C:
CD \CSHOW
CSHOW %1 %2 %3 %4 %5 %6 %7 %8 %9^Z
(The ^Z above means hold down the CTRL key and type Z). The purpose of "%1"
through "%9" is to allow you to pass command-line arguments to the program
through the batch file. Execute "CSHOW" at your DOS prompt and the batch file
is executed to load CompuShow no matter "where you are".
Start-up options
================
"Command-line switches" let you control graphics video features, program
options, and the way that the program allocates memory for various purposes.
1. In case of problems getting started
--------------------------------------
CompuShow requires at least 325k of available memory (depending on the
start-up options specified.) If the program displays an "Insufficient
memory" message, you need to make more memory available. (Remove some
memory-resident programs, for example.)
/L1 Use this switch if the screen goes blank when you start CompuShow.
Early Leading Edge "IBM compatible" computers (and other incompatible
adapters) would display black-on-black text when a program tried to
set the text-mode border color.
/T1 Use this switch for gray on black text, if you can't read the text
screen in color. Good for LCD screens.
[SETUP.DOC] Page 2
/A In the (extremely rare) case where CompuShow can't detect the type of
video adapter you have, you can FORCE it. In general, you shouldn't
need this switch, unless there's a serious problem:
/Ah Hercules monochrome graphics adapter
/Ac CGA
/Ae EGA
/Ab EGA with monochrome monitor
/Am MCGA
/Av VGA
/M Mouse cursor. The default on EGA or VGA adapters is the 'software
cursor'. On some adapters, moving the mouse may 'scramble' the text
screen so badly, that you can't use the software mouse at all. If the
software mouse does work, clicking on the mouse prompt at the bottom
of the screen allows you to select a software mouse shape or the
hardware (blinking) cursor. If the characters on the screen
occasionally become 'corrupted', click repeatedly to change to the
hardware cursor, which will restore the original characters.
/M0 Disable the mouse entirely.
/M1 Use the standard hardware mouse.
/Mn Use software cursor shape n (2..9) as indicated by /M on the
Shift-F1 box.
2. Graphics features that don't work
------------------------------------
/H0 Hardware panning on an EGA. If your screen is scrambled in 640x350x16
mode, use this switch to disable hardware panning.
/C0 Color palette setting for MCGA/VGA. Use this switch to set the palette
through the BIOS.
/[0 Disable extended 320x400x256 mode
/]0 Disable extended 360x480x256 mode
3. Special graphics modes
-------------------------
/E Enable a "Super-EGA" 640x480x16 mode
/Ea Ahead (mode 38)
/Eg Genoa (mode 115)
/Ep Paradise (mode 80)
/Et Tseng Labs (mode 37)
/Ev 'VGA' (Zenith) (mode 18)
/E71 any decimal number as listed in your owners manual
/J1 Enable PCjr (Tandy 1000) 16-color graphics.
/V Video drivers are described in detail, below.
[SETUP.DOC] Page 3
4. Program options
------------------
/Bx Buffer size, where x is S, M, or L for a Small (2k), Medium (32k) or
Large (62k) file read buffer.
/D0 Turns dithering off
/F Specifies the maximum number of files (from 0 to 9999, default 120).
If you have a sub-directory with 1500 files, use /F1500.
/G0 Turns off display of GIF comments.
/Q1 Turns on Quiet mode, so that the program doesn't make any sounds.
/R Rescaling
/R0 Original size, don't rescale anything.
/R1 Rescale most, except for 2-color images.
/R2 Rescale all images to fit the screen.
/U1 Turns on correction for gamma 1.0 true color graphics.
/X Specifies the maximum amount of XMS or EMS memory in K-bytes. By
default, CompuShow takes up to 1280k of EMS memory. If no EMS is
available, it takes up to 1280k of XMS. You can specify any amount
from 1k to 30000k (30meg).
/X2000e use 2000k of Ems
/X800x use 800k of Xms
Options and memory
------------------
In CompuShow, hold down a shift key and press F1 or right-click F1help to pop
up the Program Information box, which identifies the amount of memory used
for various purposes. This information is important for several reasons:
- The size of the "virtual screen" determines whether (and how much) you can
pan images larger than the screen, and can affect the operation of the
restore-to-previous function and transparency.
The (default) small read buffer (/B option) provides the most memory for a
large virtual screen.
Turning on PCjr graphics (/J1) takes 32k away from the virtual screen.
- If you have a lot of files in a directory, and the program needs memory to
pop up a box, it will have to "abandon" the sorted file list. The '/F'
option lets you reserve memory for a directory of up to 9999 files. Keep
in mind that reserving memory for a large directory leaves less memory for
the virtual screen.
If CompuShow uses EMS or XMS memory for the virtual screen, the /B, /J and /F
switches have no effect on the size of the virtual screen.
[SETUP.DOC] Page 4
Selecting a Video Driver
------------------------
Remember that all standard graphics modes are 'built in' to the program. If
your graphics adapter doesn't go beyond the standard modes, then you DON'T
NEED a video driver.
DRIVERS.DOC includes a complete, up-to-date list of all video drivers.
- If you have a CGA, Plantronics, AT&T DEB, or similar (older, non-VGA)
graphics adapter, just select the appropriate video driver.
- If you know you have a specific Super-VGA, pick that driver.
- If you're not sure whether you have a Super-VGA or what kind it is,
execute the WHICHDRV program. If WhichDrv doesn't identify a Super-VGA,
then you probably don't have one (and don't need a video driver).
The "/v" command-line switch tells the program to load a video driver. For
example, DRIVERS.DOC says V2=VESA BIOS Extensions.
CShow /vV2
loads that video driver. Select a graphic file and press enter to bring up
the Graphics Information Box. Up to fifteen video driver modes are assigned
the letters K through Y. Test each mode by pressing a key and keep track of
the modes which work. (If the text screen just changes color, the mode
doesn't work. If none of the video driver modes work, this driver won't do
you any good.) Assuming, for example, that modes K, L, M, and N work, exit
CompuShow, return to DOS, and do:
SETUP V2 KLMN
This will set up the video driver to be loaded automatically (so don't use
the /v command) and also tells CompuShow which modes work, so it can select
one of those modes as the best mode for display when you press the spacebar.
Erasing Files
=============
If your hard disk is crowded, and you need to erase unnecessary files after
you've printed the documentation and completed the setup:
- Execute CSHOW with all the original files present (to create CSHOW.DAT)
- We recommend that you keep a 'backup copy' of all the original files on a
floppy disk
- Erase any files that you no longer need on your hard disk. As a minimum,
you'll have THREE files: CSHOW.EXE CSHOW.DAT FONTS.DRV
If you selected a video driver, you'll also have: VIDEO.DRV VIDEO.DAT
