1. Introduction
This release of the WEITEK Power 9100 and Video Power Windows 3.1 drivers
includes the following features:
High-performance graphics drivers
WEITEK Video Power coprocessor support with autosensing
Microsoft/Intel DCI support (Video for Windows 1.1d)
MPEG playback capability
Support for a selected set of RAMDACs
Release 2.1 supports all revisions of the Power 9100 graphics controller and
autosenses the presence of the WEITEK Video Power video coprocessor. The
driver is DCI enabled, and will therefore interact seamlessly with any
software that supports DCI client. Figure 4 in the published release notes
illustrates the Power 9100/Video Power driver data flow.
The presence of a WEITEK Video Power coprocessor enables a Video Power
control panel, and the Video Power driver is dynamically loaded when activated
by the Windows Media Player or other software applications that take advantage
of Video for Windows or DCI.
The WEITEK Video Power video coprocessor provides hardware digital video
acceleration of DCI compliant CODECs (compression/decompression algorithms)
such as Indeo 3.1/3.2, Cinepak and MS Video 1. MPEG decoding and playback
support is also included in this release. Motion JPEG is available as a
separate product (part number 4800-0136-00).
Release 2.1 supports MPEG playback through the media player or through other
applications that use the Window MCI interface. MPEG audio is supported
by decoding the MPEG audio in software and outputting it to any Windows
Sound System compatible audio board. The MCI driver assumes that the MPEG
file has a .MPG file extension.
These release notes show you how to customize the installation program
for your particular board, how to install the Power 9100 Windows 3.1 driver
software, and how to modify the list of supported monitors.
This 2.1 production release consists of the 8-, 16-, 24-, and 32-bits-per-pixel
(bpp) Window drivers. The 8bpp and 16bpp drivers have a maximum resolution of
1600x1200 pixels. The 32bpp driver has a maximum resolution of 1024x768.
The 24bpp driver has a maximum resolution of 1024x768.
Figures 1 through 3 list the video modes the drivers support. Note that
the 1600x1200x8 mode requires that your board have a RAMDAC that is capable
of operating at 165 MHz or faster.
The software is distributed on three 3.5" diskettes. If you purchased Motion
JPEG, you will receive an additional diskette containing the Motion JPEG
driver. As the files on the diskettes follow normal Windows naming conventions,
their functions should be self-explanatory. Figures 5 through 7 list
the contents of the Power 9100/Video Power distribution diskettes. Figure
8 lists the contents of the Motion JPEG diskette.
Problems
There are two problems with this release we want to bring especially to
your attention. These are problems with this release only; they will be
fixed in the next release. First, Video Power is best optimized when using
16-, 24-, or 32bpp modes. Refer to section 6.2, reference numbers
383-VP and 366-VP. Secondly, there is a problem with Corel
PhotoPaint 5.0; see section 6.2 reference number 394. For a full list of
bugs, see section 6.2.

2. Adding Monitor Support Information
The P9X00RES.DAT file contains two types of information that are used by
the install program: system parameters and monitor configuration.
System parameters. This list of variables can be used by an OEM provided
installation program. Refer to figure 11 (page 10).
If you are using the WEITEK provided installation, refer to sections 3
and 4 for information on customizing the installation.
Monitor configuration. P9X00RES.DAT also contains monitor configuration
information. You can edit P9X00RES.DAT to add monitor configuration
information for new monitors you wish to support.
During the first installation of the Power 9100 Windows drivers, the
installation program, WINSTALL.EXE, gets initial variables and monitor
configuration information from the text file called P9X00RES.DAT.
When the user runs the installation program, he may select options other
than the defaults. WINSTALL.EXE uses these selections, reads the default
information and the monitor information from the P9X00RES.DAT file, and
generates an initialization file, WINSTALL.EXE, and modifies the SYSTEM.INI
file.
Each time Windows is started, the monitor timing information and the options
chosen are read out of P9X00RES.INI and SYSTEM.INI and used by the drivers.
When the user executes the installation program (to change an option, for
example), the chosen option and monitor timing information is copied into
the SYSTEM.INI file and the P9X00RES.INI file. Never change variable settings
by editing the SYSTEM.INI file or the P9X00RES.INI file. Instead, modify
the P9X00RES.DAT file before installation and/or select appropriate options
from the install menu.
The following subsection, 2.1, describes the format of the P9X00RES.DAT
file, so that you can modify it to support other monitors; the section
also describes how to read the P9X00RES.INI file.
2.1. P9X00RES.DAT File Format
The Windows driver installation program, WINSTALL.EXE, reads P9X00RES.DAT
and SYS_DEF.INI (see section 4) to get the system parameters and the list
of monitors, resolutions, and CRT parameters to display in the Power 9100
Install dialog box. P9X00RES.DAT is an ASCII text file; it can be examined
and modified like any other text file. Some variables appear in both the
P9X00RES.DAT file and the SYS_DEF.INI file. Whenever you change any setting
that is specified in both files, be sure to make the change in both files.
P9X00RES.DAT contains four types of information:
1. A variable contains a value for things like the bus type (BusType),
memory address (MemAddr), or default display mode (DefMode). The P9X00RES.DAT
file is required to contain a value for the DefMode variable. This is an
example of a valid variable for DefMode:
DefMode = 1024x768x8
Refer to figure 11 for a list of valid variable settings. In this
table, Default refers to settings as shipped by WEITEK.
Note that variable names (such as DefMode in the example above)
are case sensitive, and must be entered exactly as shown. The settings
(anything to the right of the equals sign) are not case sensitive, except
as noted.
2. A monitor block lists the resolution and refresh rates for a particular
monitor. A monitor block begins with a left square bracket followed immediately
by an upper case "M" and ends with a blank line (two newlines). The
first equate in a monitor block gives the monitor ID string. Subsequent
equates in the block give the resolutions and refresh rates the monitor
supports. Occasionally, more than one refresh rate appears for the same
resolution, as in this example of a valid monitor block:
[M1]
name = "Toshiba P20C900"
timing0 = T00:1024x768x60Hz
timing1 = T00:1024x768x70Hz
A monitor block is not permitted to have more than one timing for
a given resolution and refresh rate. For example, the following monitor
block is not valid:
[M2]
name = "Sony 1606"
timing0 = T00:1280x1024x60Hz
timing1 = T01:1280x1024x60Hz
3. A timing block provides the actual timing parameters for a particular
resolution and refresh rate. A timing block begins with a left square bracket
followed immediately by an upper case "T" and ends with a blank line
(two newlines). The first line of a timing block contains the timing identi-
fication string between the square brackets. The fourteen subsequent lines in
the block provide timing parameters ranging from Horizontal Dot Rate in MHz
to Vertical Sync Polarity. The next 10 lines are optional; they are used
to set the ICD 2061 and/or the IBMRGB525 as shown in figure 10. White space
is not permitted between newlines inside a Timing block. The fourteen equates
(and ten optional equates, shown in bold-face type) that appear in
a timing block contain parameters for the following, in order:
[T00:1024x768x60Hz]
hdr= Horz. Dot Rate (with a MHz suffix)
hsp= Horz. Sync Pulse (in dots)
hbp= Horz. Back Porch (in dots)
had= Horz. Active Display (in dots)
hfp= Horz. Front Porch (in dots)
hco= Horz. Cursor Offsett
hp= Horz. Sync Polarity (positive or negative)
vlr= Vert. Line Rate (with a Hz suffix)
vsp= Vert. Sync Pulse size (in lines)
vbp= Vert. Back Porch (in lines)
vad= Vert. Active Display (in lines)
vfp= Vert. Front Porch (in lines)
vco= Vert. Cursor Offset
vp= Vert. sync Polarity (positive or negative)
IcdSerPixClk = (default)
IcdCtrlPixClk = 010 (default)
IcdSer525Ref = 50 (default)
IcdCtrl525Ref = 010 (default)
525RefClkCnt = 19 (default)
525VidClkFreq = (default)
MemCfgClr = FFFFFFFF (default)
MemCfgSet = 00000000 (default)
SrtCtlClr = FFFF (default)
SrtCtlSet = 0000 (default)
Refer to example timing block in section 2.2.
4. A comment line begins with a semicolon. Comments are not permitted
on the same line as any of the other types of information.
Finally, with regard to formatting rules for this file, white space is
permissible at the start of any line. White space is permissible immediately
before or immediately after an equals sign. Quotation marks must be used
to include white space in a value to the right of an equals sign. No line
may exceed 255 characters.
2.1.1. Using the Optional Timing Parameters
The optional timing parameters are used to support different methods of
programming the programmable PLL clock sources: the ICD 2061A and the IBMRGB525.
Twenty-four bytes have been appended to the timing block to accommodate
the ten optional equate statements.
You need not enter all ten optional statements; choose the statements that
apply to your board. If the optional statements are not needed, omit them
from the timing block.

2.2. P9X00RES.INI File Format
The Windows driver installation program, WINSTALL.EXE, creates the
P9X00RES.INI file containing timing and system information from P9X00RES.DAT
for the monitor and refresh rate for the selected monitor. Running
WTKSETUP.EXE overwrites any existing copy of P9X00RES.INI in the directory.
Note that the driver modifies and uses the SYSTEM.INI file. The
P9X00RES.INI file is included for compatibility with specific applications.
Contact your WEITEK representative for more information.
P9X00RES.INI contains four types of information:
1. A comment. The first part of P9X00RES.INI is a header in which each
line starts with a semicolon. The header gives an explanation of values
in a timing block.
2. A link begins with a left square bracket followed immediately by a
mode identification string and a right square bracket. A mode identification
string is a resolution identification string (for example, 640x480) with
a number of bits per pixel concatenated to it (for example, 640x480x4).
A link has only one other line, which contains an equate to a resolution
identification string. An example of a link is as follows:
[1024x768x24]
link=1024x768
3. A timing block begins with a left square bracket followed immediately
by a resolution identification string and a right square bracket. This
differs from P9X00RES.DAT, in which timing blocks are headed by a timing
identification string. The fourteen subsequent equates in the block provide
timing parameters ranging from Horizontal Dot Rate in MHz to Vertical Sync
Polarity. The ten optional equates are shown in bold-face type. A
timing block may include only the optional equates needed or no optional
equates. (See figure 10.) An example of a timing block is as follows:
[1024x768]

3. Customizing Video Driver Settings
The default settings for the Video Power driver can be customized by changing
the default settings in the COPRO.INI file, as shown in figure 12. The
settings in this file affect the Video Power drivers only.

4. Customizing the Installation Settings
The default settings for the Power 9100 installation can be customized
by changing the variable settings in the SYS_DEF.INI file (figure 13).
This file is used by the WEITEK installation program. Some of the variables
in this file are also specified in the P9X00RES.DAT file. Whenever you
change any setting that is specified in both files, be sure to make the
change in both files.

for more details.
5. Installing the Drivers
This section shows you how to install and select the Power 9100 Windows
drivers, and also how to change options and drivers whenever you wish from
inside Windows.
5.1. Preparation
The following installation procedure (section 5.2) assumes that the Power
9100 board is already installed in your system. If it is not, install it
now.
Note: We recommend installing the Video for Windows software (section 5.6)
before installing the Power 9100 and Video Power drivers (section 5.2-5.5),
although it is not imperative to do so.
If Windows is not installed on your system's hard disk:
If Windows 3.1 is not installed on your system's hard disk, install it
now using the instructions given in the Microsoft Windows User's Guide.
During the Windows installation, you will specify a type of display adapter.
It is important to select VGA from the list of available drivers and finish
the installation. Since the Power 9100 board has its own VGA controller,
we can use a VGA display to help us accomplish the initial driver
installation.
If you have any earlier versions of the WEITEK drivers installed on your
system:
If you have any earlier versions of the WEITEK Power 9000 or Power 9100
drivers on your system, remove them using the following procedure:
1. Open the Program Manager window.
2. Select Weitek Installation from the Program Group or Window pull-down
menu.
3. Double click on the Power 9000 Installation or Power 9100 Installation
icon in the Weitek Installation window.
4. Click on the Remove button in the pop-up window.
The WEITEK Power 9000 or Power 9100 drivers are removed and Windows asks
for the system to be rebooted in standard VGA mode. Reboot in standard
VGA mode and continue with the installation of the Power 9100 Windows Drivers
2.1 as described in section 5.2.
If this is the first installation of the WEITEK Power 9100 drivers:
If this is the first installation of the WEITEK Power 9100 drivers and
if Windows is already installed, use the following procedure to configure
the Windows display option to standard VGA:
From DOS:
1. Move to the directory where Windows is installed (usually C:\WINDOWS).
2. Type CD \WINDOWS and press Enter.
3. Type SETUP and press Enter.
After a few seconds, the Windows Setup screen will appear.
4. Using the up-arrow key, move the highlight up to the Display
line and press Enter.
5. From the menu, move the highlight to VGA and press Enter again.
This sets the video driver to be VGA.
6. Press Enter twice more to complete the driver change.
7. To start Windows, type WIN and press Enter.
From Windows:
1. Select the Main program group.
2. Double click on the Windows Setup Option icon.
3. If VGA is already chosen, click on Cancel.
If VGA is not chosen, click on Options, then Change System Setup.
4. Choose Display. Scroll through the available options and pick VGA.
Click on OK.
5. Follow the displayed directions to restart Windows.
Continue with the installation of the Power 9100 Windows Drivers 2.1
as described in section 5.2.
5.2. Installing the Power 9100 and Video Power Drivers
1. Insert the Power 9100/Video Power Windows diskette #1 into either drive
A: or drive B:.
2. From the Windows Program Manager, select the File menu item and choose

not on the list, select Generic. Click on the Install button.
5. A pop-up window is displayed reminding you that Microsoft Video
for Windows must be installed on your system in order to use Video Power.
Click on the OK button to continue.
(Note: Installing Video for Windows is covered in section 5.6)
6. A pop-up window is displayed asking whether to install the drivers
and restart Windows. Click on the YES button to install the drivers. The
driver files are copied from the distribution diskette to the Windows system
directory on your hard disk.
7. The WINSTALL pop-up window is displayed. Click on OK to restart Windows.
8. When the installation is completed, the WEITEK Power Utilities window
is displayed opened. See figure 15 in the published release notes. This
window contains three icons: Setup, Install, and Release Notes.
5.3. Changing Monitor Type After Installation
The selected monitor type can be changed after installation. To change
the monitor type:
1. Select the Install icon in the Power 9100 Utilities Program Group (see
figure 15 in the published release notes).
2. When the Install dialog box opens, click on the arrow to the right
of the monitor drop down list (see figure 14 in the published release
notes).
3. A three-item list is displayed. Scroll through the list to find the
monitor that will be connected to your system. If your monitor is not on
the list, select Generic.
4. Click on the OK button. The monitor timing information in the SYSTEM.INI
file is replaced with the timing information for the new monitor selected
in step 3.
5.4. Changing the Power 9100 Setup
In the WEITEK Power Utilities window (figure 15 in the published release
notes), open the Setup icon to access the WEITEK Power 9100 Windows Setup

6. Notes, Known Bugs and Limitations
6.1. General Notes
1. 1280x1024 is not supported in 24bpp mode for Video Power.
2. Video Power is best optimized when using 16, 24, or 32 bpp modes. Refer
to section 6.2, references number 383-VP and to section 6.3, reference
number 366-VP.
3. Note that bug reference number 394 involving Corel Photopaint 5.0 will
be fixed in the next release.
4. Because MPEG software decode is very CPU intensive, MPEG playback works
best on Pentium-based computers. This also applies to Motion JPEG.
5. Other applications that install software could install an older version
of Video for Windows, thereby causing Video Power to stop working.
