Radius MultiView 24 Release 1.03
=================================
Thank you for your purchase of the Radius MultiView 24 interface.
This README contains application notes, and unique installation tips
for the MultiView 24.

Windows 24-bit Support
======================
The MultiView 24 has been tested with the most popular software available
at the time of release. While 24-bit color is relatively new in the
Windows environment, most new applications are 24-bit compatible and some
even depend on a 24-bit color card for full functionality. This is
supported by improvements Microsoft made in Windows 3.1 to address minor
problems Windows 3.0 experienced with 24-bit interface cards. This
section highlights a few unique peculiarities working with Windows and
Windows applications in a 24-bit color environment.
The notes below are arranged in the following format:
Program Name
Description of 24-bit impact
Resolution if available
Windows 3.0
Some color icons in the Program Manager appear black and white
while other are normal.
Windows 3.1 corrects this cosmetic problem. Windows 3.0 users
can fix this using a shareware program called Iconfix by
Playroom Software.
Windows 3.0
Using bitmaps created for OS/2 as wall paper may cause Windows to
crash
Windows 3.1 corrects this problem. Do not use bitmaps for
OS/2 as wall paper in Windows 3.0.
Screen savers in After Dark, Intermission, Norton Desktop for Windows,
and others
Fish swim backwards in screen savers.
Windows 3.1 corrects the problem.
Various Applications
Some applications use fonts in status bars, dialogs or menus that
are larger then the space provided causing the fonts to overlap
their designated area.
This cosmetic problem rarely interferes with operation of the
program. If it is bothersome, try running the offending
application using the MulitView 24's Large Font Windows
Driver.
After Dark 1.0A
Running After Dark's Punch-Out module will result in a UAE.
Windows 3.0 cannot handle large virtual bitmaps.
The problem is corrected in Windows 3.1.
Charisma v2.0
Import an image file and a black square the size of the original
image appears.
Charisma is reading the color palette backwards. Charisma
assumes RGB and the palette is actually BGR.
ROM Addressing
==============
The MultiView 24 uses 8514/A technology and follows the guideline set
forth by IBM for ROM addressing. For information on how to set-up the
MultiView 24 card and its ROM address, refer to the MultiView 24 User's
Manual.
In the event that the two addresses for MultiView 24's ROM are being used
by other cards or software, you can resolve the conflict in one of two
ways.
Option one (ISA/EISA systems only) is to disable the ROM on the
MultiView 24 by moving the jumper on JP1 to the position next to
the interface card and run MV24INIT.EXE upon bootup. This program
is a replacement for the on-board ROM (refer to your manual).
Option two is to change the address of the conflicting device. Refer
to the MultiView 24 manual for troubleshooting instructions on how to
identify a conflicting device. Once identified, refer to the manual
of the conflicting device for instructions on changing its address.
VGA Pass-through
================
S3 or 8514/A based VGA graphic cards like the Diamond Stealth, Orchid
Fahrenheit 1280, HP Ultra, ATI Graphics Ultra, and others are
incompatible with the MultiView 24.
This is due to the S3 or 8514/A chips on such cards. Like the
MultiView 24, these cards are based on 8514/A technology. Per
IBM's specification, two 8514/A cards can not be in the same
system at the same time.
If your S3 or 8514/A based card includes a utility to disable
the 8514, do so. If not, you will need to replace the card
with a card that uses a VGA chip. Make sure that whatever
card you choose has a feature connector for VGA pass-through.
Various Applications
Pixel jitter or incorrect colors display when running Windows in
a high resolution or HiColor VGA mode passed through the
MultiView 24 interface card.
VESA standards for VGA pass-through provide for 6-bit pass-
through signals of a limited dot clock. 8-bit DAC modes or
15- or 16-bit color modes (32768 or 65536 colors) exceed that
requirement and cannot pass-through effectively. Depending
on your computer system, you should reliably be able to
pass-through signals up to 70Hz refresh at resolutions of
1024 x 768 with 256 colors. If you are experiencing problems
with your pass-through, refer to your VGA card's manual and
verify the DAC setting (not the color setting) is 6-bit (not
8-bit). If problems persist, follow the directions for your
VGA card to lower the refresh rate.
Diamond Speedstar VGA Card (and other VGA cards with feature connectors
using pin 26)
The 26th Pin of the VGA Feature Connector on the Diamond Speedstar
card exists. The VESA guideline for VGA Feature Connectors
requires the pin be absent. Pin-socket #26 of the MultiView 24
pass-through cable is plugged with a small piece of plastic to
prevent improper connection of the cable to a VESA compliant
feature connector.
Carefully remove the plastic filler from the pass-through cable
using a needle or pin. Once removed you will be able to
connect the pass-through to the interface card. NOTE: Be sure
to connect pin 1 of the pass-through cable to pin one of the
interface card's feature connector (pin 1 of the cable is on
the side with the red cable lead).
Running OS/2
============
Specific drivers for OS/2 are not included with the MultiView 24. If
you need to run OS/2, do so using the 8514/A driver provided with
OS/2.
Running AutoCAD
===============
The MultiView 24 will support AutoCAD in 8514/A mode providing
resolution of 1024x768 and 256 colors. To install AutoCAD for 8514/A,
follow the installation instructions in the AutoCAD manual.
