FiberOptics 1.1 By Joseph W. Szarmach Jr.
Copyright (C) 1994 JWS Enterprises
FiberOptics may be freely distributed, but may not be sold.
FiberOptics is a collection of SuperVGA screen saver like graphics
demos which resembles a screen saver program. Each demo looks like a
fiber-optic plant, kind of like those fiber optic plants at the mall.
To start FiberOptics, at the DOS prompt type:
c:\>FIBER
and press enter. FiberOptics will scan your video graphics adapter
for VGA and Super VGA support. In most cases, FiberOptics will
automatically use the highest video mode supported by your VGA card.
Supported video modes include:
320x200x256 colors - standard VGA (not recommended)
640x400x256 colors - For cards with 256K video RAM
640x480x256 colors - For cards with 512K video RAM
800x600x256 colors - For cards with 512K video RAM
1024x768x256 colors - recommended mode - For video cards with 1 meg.
video RAM.
FiberOptics will NOT detect the capabilities of your monitor however.
For example, it is possible that a video card may be capable of
1024x768 but the monitor only capable of 800x600. If such is the
case, your monitor will become unreadable (press the escape key to
exit). You may force FiberOptics to attempt to use any of the video
modes above.
Forcing A Video Mode
--------------------
As discussed above, it is possible that FiberOptics will not detect
and use the best possible video mode for your computer. There are two
possibilities which may occur:
1) Your system is capable of displaying a higher video mode than
FiberOptics automatically detects. FiberOptics checks for something
called "VESA extensions" which contains a list of video modes
supported by your video card. If they are not present, FiberOptics
will default to standard VGA (320x400). Your system may still be able
to display super VGA however. FiberOptics supports many super VGA
video cards including Tseng 4000, Chips & Tech, Trident, Ahead,
Cirrus 54xx, S3 and VESA. If FiberOptics defaults to a low
resolution mode and you think you have a super VGA card, it is worth
trying to select the mode yourself.
2) FiberOptics may detect a video mode higher than your monitor can
display. In such cases, it is possible to select a lower video mode.
The following video modes are defined:
MODE
----
/1 - 320x200x256 colors - For standard VGA Mode
/2 - 320x400x256 colors - This mode is the default mode for
standard vga users. If your system cannot make use of this
mode, try mode 1.
/3 - 640x400x256 colors - This is the maximum resolution if your
video card has only 256K video RAM on the VGA card.
/4 - 640x480x256 colors - 512K video RAM required. Most monitors
can easily handle this video mode.
/5 - 800x600x256 colors - 512K video RAM on VGA card required. This
is true super VGA.
/6 - 1024x768x256 colors - 1 Meg video RAM on video card required.
This is the recommended mode.
To force FiberOptics to use one of the above video modes, enter the
mode on the command line. For example:
c:\>FIBER /5
will force FiberOptics to use the 800x600x256 color mode.
C:\>FIBER /4
will force fiber optics to use the 640x480x256 color mode.
Remember, if your monitor becomes unreadable, your system is not
capable of that video mode. Press escape to exit (or worst case,
reboot your computer).
WHAT'S NEW WITH VERSION 1.1?
----------------------------
1) A 320x400x256 color mode has been added. If FiberOptics detects
standard VGA, this mode will be used (as opposed to 320x200 with
version 1.0).
2) Users can select (force) any video mode. Six modes are supported.
3) New "plants" and shapes have been added. There are 14 different
plants/screens.
