ΓòÉΓòÉΓòÉ 1. Information about installed adapter ΓòÉΓòÉΓòÉ
This page shows information about your installed graphics adapter.
In the first group the exact name and model of your installed board are
listed.
The group "Technical Information" shows hardware details of your
installed board:
Chipset
Video Memory
RAM-DAC
Bus
Under "Driver Version" the revision level of the currently installed
driver is displayed. This value is only of interest if you already have
an ELSA driver installed and want to upgrade to a newer version.
ΓòÉΓòÉΓòÉ 1.1. Chip set ΓòÉΓòÉΓòÉ
The chip set is an essential part of your graphics board and determines how a
graphics driver accesses the various functions of the graphics board. The
driver must be suitable for your board's chip set. Even if driver versions for
earlier chip sets might work with successor models, it might well be that they
do not make use of improved facilities in the new chip sets. For this reason,
be sure to use the latest drivers for your board model.
ΓòÉΓòÉΓòÉ 1.2. Video Memory ΓòÉΓòÉΓòÉ
Video memory contains a complete pixel-for-pixel equivalent of the displayed
screen content and is periodically read out by the chip set to the screen.
The maximum resolution and color depth depends on the amount of installed video
memory. See the list below for some examples.
1 MB Video Memory: 640 x 400 in Truecolor mode
2 MB Video Memory: 800 x 600 in Truecolor mode
4 MB Video Memory: 1152 x 864 in Truecolor mode
8 MB Video Memory: 1600 x 1200 in Truecolor mode
Graphics boards of the Winner 1000 series are equipped with D-RAM, those of
the Winner 2000 series with V-RAM. The markedly higher speed of V-RAM boards
is due to the fact that with V-RAM, which was specially developed for video
applications, the transfer of the video memory contents to the screen can be
carried out parallel with other video memory accessing.
ΓòÉΓòÉΓòÉ 1.3. RAMDAC ΓòÉΓòÉΓòÉ
The RAMDAC converts the image information which the chipset reads out from the
video memory into analog values for the monitor. The maximum pixel frequency of
the RAMDAC directly influences the maximum possible screen resolution and scan
rates.
ΓòÉΓòÉΓòÉ 1.4. Bus ΓòÉΓòÉΓòÉ
Your graphics board is connected to your computer via the bus. The capabilities
of your bus system directly influence the speed with which display data is
transferred to your graphics board.
ΓòÉΓòÉΓòÉ 2. Installpath and Packages ΓòÉΓòÉΓòÉ
On this page you can select the path to install to and the packages you wish to
install.
If you want detailed information about what is copied and how, select one of
the following items:
Packages
WPS-Object
Drives
Folders
Installpath
Installation Progress
ΓòÉΓòÉΓòÉ 2.1. Packages ΓòÉΓòÉΓòÉ
If you don't want to copy all the files to your hard disk, or if you have
insufficient space, you can select the packages you want to install.
These are the packages you can install:
Monitor Database:
The setup program requires your monitor specifications. The monitor
database contains specs for more than 350 monitor types, so in most cases
you should be able to find the necessary information here.
Packed Drivers:
The packed drivers consist of drivers for OS/2 as well as WinOS/2 in
packed form. Copying them to your hard disk will speed up the
installation process considerably.
ReadMe File:
This file contains last minute information about the driver, such as
known bugs, limitations, etc. This file is also displayed on the startup
page of the Setup utility.
Resolution Manager:
The resolution manager can be used to select or define resolutions after
the installation process has been completed. It consists of the pages
"Adapter Info" and "Resolution".
ΓòÉΓòÉΓòÉ 2.2. WPS-Object ΓòÉΓòÉΓòÉ
If this box is checked, the utility will create a Resolution Manager WPS-Object
on your desktop.
This is only carried out if the item "Resolution Manager" or "ReadMe File" in
the "Packages" list box is selected.
ΓòÉΓòÉΓòÉ 2.3. Drives ΓòÉΓòÉΓòÉ
Here you can select the drive you want to copy the selected packages to.
ΓòÉΓòÉΓòÉ 2.4. Folders ΓòÉΓòÉΓòÉ
Here you can select the folder you want to copy the selected packages to.
Double-clicking on a folder will display its sub-folders.
ΓòÉΓòÉΓòÉ 2.5. Installpath ΓòÉΓòÉΓòÉ
Here you can enter your installation path manually if you don't want to use the
"Drives" and "Folders" menus for specifying it.
If you enter a non-existent path, it will be created.
ΓòÉΓòÉΓòÉ 2.6. Installationprogress ΓòÉΓòÉΓòÉ
This gives you the percentage of installation already completed.
ΓòÉΓòÉΓòÉ 3. Resolution and Monitor ΓòÉΓòÉΓòÉ
The page "Resolution" allows you to choose the resolution and to specify your
monitor.
Specifying the resolution involves defining color depth, X/Y resolution and
vertical frame rate. Frame rates in brackets are not supportet by your monitor.
The correct description of your monitor is essential to ensure that it is not
operated outside its limits. After selecting your resolution and monitor,
these values can be retained by pressing the "Set" button.
Warning: Before displaying the test screen, the utility checks if your monitor
can support the mode selected. If you have specified a monitor type with a
higher horizontal scan frequency (kHz) than that of your own monitor, your
monitor could be DAMAGED. Please check before testing that the specification of
the monitor is correct, with particular attention to the horizontal scan
frequency.
ELSA will not be held responsible for damages caused by incorrect use of this
utility.
If the standard resolutions are not sufficient for your purposes, or if your
monitor is not to be found in the monitor database, press the "Add" button. You
will then be able to define custom resolutions and monitors.
A red status line will inform you about a prefered mode that might be defined
in your CONFIG.SYS.
ΓòÉΓòÉΓòÉ 3.1. Prefered Modes ΓòÉΓòÉΓòÉ
You can define prefered Modes by setting environment variables in your
CONFIG.SYS:
SET ELSA_RESET=[H|L]
Use this to reset the selected resolution to one of these:
H = 1024x768x8@75Hz
L = 640x480x8@60Hz
This setting is valid as long as it appears in the CONFIG.SYS.
SET TIM=....... (copy TIM-line from WINMAN.INI)
This makes the video timing produced by WINMAN applicable to the
WPS. The driver takes the TIM line prior to the mode setting done by
the "ELSA Resolution Manager". However, it is lower in priority than
the ELSA_RESET line.
ΓòÉΓòÉΓòÉ 4. Custom Resolutions ΓòÉΓòÉΓòÉ
Use this dialog for specifying custom resolutions.
After pressing the "Add" button the program checks if the resolution you have
entered is valid. You will then be able to select the resolution. You can
delete custom-defined resolutions by pressing the "Delete" button. To validate
the changes made in this dialog, press the "OK" button.
ΓòÉΓòÉΓòÉ 5. Custom Monitors ΓòÉΓòÉΓòÉ
If if your monitor is not entered in the monitor database, you can specify it
with this dialog.
After pressing the "Add" button the monitor will be added to the database. You
can delete custom-defined monitors by pressing the "Delete" button. To validate
the changes made in this dialog, press the "OK" button.
Warning: Make sure you have entered a horizontal scan frequency not exceeding
the maximum horizontal frequency of your monitor; otherwise your monitor could
suffer severe damage! Refer to your monitor's manual for the maximum horizontal
scan rate allowed.
ΓòÉΓòÉΓòÉ 6. Drivers ΓòÉΓòÉΓòÉ
Your configuration makes it possible to install several drivers
OS/2 WARP 4 supports the GRADD (Graphic Adapter Device Driver) driver model.
You can install this driver especially designed for OS/2 WARP 4 or our standard
OS/2 driver.
The GRADD display driver requires essential system files which are not
installed during the OS/2 WARP standard installation. Thus it is essential that
you install VGAGRADD once.
Installation VGAGRADD
ΓòÉΓòÉΓòÉ 6.1. Installation VGAGRADD ΓòÉΓòÉΓòÉ
To install VGAGRADD you have to:
- Double-click on "OS/2 System".
- Double-click on "System Setup".
- Double-click on "Install/Remove".
- Double-click on "Selective Install".
- Click on "Primary Display".
- Select "Video Graphics Array (VGA) GRADD" in the list.
- Follow the instructions of the install program.
ΓòÉΓòÉΓòÉ 7. Information about settings ΓòÉΓòÉΓòÉ
Before starting the installation, check this summary of settings.
If the displayed values are correct, press the "INSTALL" button to start the
installation.
