-
- 1.0 Introduction
-
- VDIF.EXE is designed according to the VESA Display Information Format
- (VDIF) standard 1.0. It allows a monitor to be added directly to the
- monitor list of the install program for the mach32 using a .vda or .vdb
- file. The .vda or .vdb file lists data for each of the available vertical
- scan frequencies of a given monitor for the following four display modes:
-
- 640x480
- 800x600
- 1024x768
- 1280x1024
-
- VDIF.EXE will search through the .vda or .vdb file and select the "best"
- data for each of the four modes listed above. The best data is
- defined as the data best matching the mach32 timings parameters, and having
- the highest vertical scan frequency, with non-interlaced displays chosen
- before interlaced displays. If no data is found for a mode, then that mode
- is considered to be unsupported.
-
- To use VDIF.EXE, simply include the name of the .vda or .vdb file
- (including the extension) on the command line. The program will display
- the modes that it selects and modify the "MONITOR.DAT" file. The original
- MONITOR.DAT file is simply renamed MONITOR.BAK, in case it needs to be
- restored. Please refer to the example in Section 3.0 below.
-
- Only one monitor can be added to the monitor.dat from a VDIF file at a
- time. To replace one VDIF monitor with another, simply run the vdif.exe
- utility again with the name of the VDIF file describing the new monitor.
-
- If you do come across any problems, please report them as soon as
- possible by fax or CompuServe to ATI, using the attached form.

- 2.0 Requirements
-
- - ATI Accelerator Card:
-
- GRAPHICS ULTRA PRO
- GRAPHICS ULTRA +
- GRAPHICS WONDER
-
- 3.0 Running the Program
-
- To add a monitor to your MONITOR.DAT file, copy the .vda or .vdb file to
- the directory containing the mach32 install program and run the following:
-
- VDIF [filename.VDA]
- or VDIF filename.VDB
-
- where filename is the name of the .VDB or .VDA file supplied by your
- monitor manufacturer. If filename is not specified, VDIF will prompt
- for a filename.
-
- NOTE: VDIF modifies the MONITOR.DAT file residing in the mach32 install
- directory. The old MONITOR.DAT file will be placed in a new file
- called MONITOR.BAK
-
- *****************************
-
- 4.0 .VDA and .VDB Files
-
- The .vda and .vdb files mentioned above contain critical information which
- the mach32 card requires to properly control a particular monitor. The
- ascii text format (.vda) and the binary format (.vdb) contain the same
- information in different forms. Both formats are translated by the VDIF
- utility into a file which is readable by the mach32 installation utility.
-
- The installation diskette includes some sample .vda files. Please make
- sure your monitor is compatible with the data in the sample .vda files
- before using it. Improper use of an inappropriate .vda file may cause
- permanent damage to your monitor. Specific .vda and .vdb files are
- provided by monitor manufacturers. Please note that .vda and .vdb
- files are provided by your monitor manufacturer and they may not be available
- for all makes and models.
-
- Please note that the three .vda files included (NEC_3FGE.VDA, NEC_4FGE.VDA,
- and NEC_5FGE.VDA) do not include data for resolutions of 1280x1024 pixels
- because the monitors are physically incapable of supporting that resolution.
-
- *****************************
-
- 5.0 Approximation Errors
-
- VDIF.EXE sometimes must approximate monitor information for the mach32
- install. An error in approximation may degrade video performance.
- For this reason, VDIF will issue a warning if an error in
- approximation occurs.
-
- If the .vda or .vdb file passed to VDIF on the command line is not of the
- standard format, or if it does not contain enough information, VDIF will
- not be able to find mode information, and no modes will be supported.
-
