This allows developers who use AIL/32 in their products to easily add native UltraSound support. It also allows end users to easily 'back patch' products which have shipped without UltraSound drivers (in effect adding native UltraSound support to games which have shipped without it). Developers should proceed to chapter 3 and read the information there. Other users should read on. Advanced users may find the developer of some interest. Some products which use AIL/32 and can be back patched with these drivers are: IndyCar Racing Shadow Caster Sim City 2000 SVGA Air Warrior Syndicate Notes: IndyCar racing only supports engine noises and tire squeals with FM based sound cards. Hence if you use these drivers you will not get either of these sound effects. For sound effects use the Sound Blaster (TM) drivers with SBOS -o3. It is unlikely you will be able to use an AdLib compatible card at the same time as these drivers, due to timer conflicts between the 2 sound cards. This has been requested by several IndyCar owners. Sierra does not use AIL/32 and hence these drivers will not work with the latest Sierra 32-bit games. However 32-bit Sierra drivers are under development and will be available soon. 2.0.0 ************ CHAPTER 2. - HOW TO 'BACK PATCH' GAMES **************** 1. After installing your game, back up all of the games sound drivers. The drivers ususally have the extension .DLL. 2. Copy the files LOADPATS.EXE and PATCHES.INI into the directory the game is installed in. 3. Copy GUSMID32.DLL over one of the games music drivers (preferably a General MIDI driver). The most common names for the music drivers are: A32MT32.DLL - MT-32/General MIDI driver A32SPKR.DLL - PC Speaker Music driver A32ADLIB.DLL - AdLib Music Driver A32ALGFM.DLL - AdLib Gold Music Driver A32SBFM.DLL - Sound Blaster Music Driver A32SP1FM.DLL - Sound Blaster Pro 1 Music Driver A32SP2FM.DLL - Sound Blaster Pro 2 Music Driver A32PASFM.DLL - Pro Audio Spectrum Music Driver A32PASOP.DLL - Pro Audio Spectrum (OPL3) Music Driver A32MT32S.DLL - MT-32/General MIDI driver (SB MIDI interface) A32ARXM.DLL - ARIA Music Driver 4. Copy GUSDIG32.DLL over one of the games digital drivers. The most common names for the digital drivers are: A32SBDG.DLL - Sound Blaster Digital Driver A32SBPDG.DLL - Sound Blaster Pro Digital Driver A32PASDG.DLL - Pro Audio Spectrum Digital Driver A32ALGDG.DLL - AdLib Gold Digital Driver A32ARDG.DLL - ARIA Digital Driver 5. Run LOADPATS by typing LOADPATS <ENTER> NOTE: The batch file COPYDRVS.BAT provided in this package is designed to perform steps 1 to 5 for you automatically PROVIDED the drivers use the standard names listed above, or, you are patching Syndicate. In particular the game must have one of the following file names: A32MT32.DLL A32SBFM.DLL A32SBDG.DLL To use COPYDRVS type: COPYDRVS dir_name <ENTER> where dir_name is the directory where the games sound drivers are installed. e.g. COPYDRVS C:\INDYCAR <ENTER> or COPYDRVS C:\SC2000\SOUND <ENTER> or COPYDRVS C:\SYND\DATA <ENTER> 6. Run the game's setup or install software (provided it has one). Configure the games sound to use the drivers you copied the UltraSound drivers over. If you used COPYDRVS and it worked, select in the following order: Sound Blaster for digital, General MIDI for music. Sound Blaster for digital, MT-32 for music. Sound Blaster for both digital and/or music. Now everytime you run your game: 7. Run LOADPATS. 8. Start your game. 3.0.0 ************** CHAPTER 3. - DEVELOPER INFORMATION ****************** These drivers are for use with the Rational DOS4GW DOS extender only. Drivers for other platforms can be made available if interest is shown. Files of interest: GUSDIG32.DLL is a PCM sample playback driver. It will play back most forms of data except Sound Blaster ADPCM compressed samples. GUSMID32.DLL is an XMIDI driver, designed to play General MIDI sequences. By editing PATCHES.INI it can be used to play back sequences for other synths (MT-32 sequences for example). LOADPATS.EXE and PATCHES.INI are also required (see below). There are several differences between these drivers and 32 bit AIL drivers for other cards. * LOADPATS.EXE must be run before either of the drivers will work. This is easily accomplished by using a batch file to load your product and calling LOADPATS at the start of this batch file. If LOADPATS fails it will return a DOS errorlevel of 1, otherwise it returns a 0. You can use this to exit from the batch file on an error. The following is an example batch file: @echo off loadpats if errorlevel 1 goto end rungame :end LOADPATS loads patches onto the UltraSound DRAM and sets up several parameters on the UltraSound card required for the AIL drivers to operate. It is NOT a TSR. Do not run another UltraSound application between running LOADPATS and your product. * The drivers ignore hardware parameters passed by AIL_detect_device and AIL_init_driver. The hardware parameters are taken from the ULTRASND environment variable when LOADPATS is run. * AIL_detect_device will check to make sure LOADPATS has been run. However it will not check to see if the hardware irq or DMA settings are in conflict with another device. This should not be a problem since the ULTRASND environment variable is used for most UltraSound software, and hence must be correct for the UltraSound to operate. * The UltraSound drivers WILL work properly with hardware irq's higher than 7. Other drivers will not due to limitations of the DOS4GW extender. ----------------------------------------------------------------------------- INFORMATION ON LOADPATS: LOADPATS is a simple program which loads the MIDI patches and information on how to play them onto the UltraSound card. Running LOADPATS gives a similar functionality as having ROM samples. The patches loaded are specified in PATCHES.INI, and are loaded in the order specified, until the UltraSound on board memory is full. Listing only the patches used in your sequences will result in optimum performance. See the header in PATCHES.INI for more information on creating a custom .INI file. Command line options: -H -? Display a help screen. -16 Load patches at 16 bit instead of 8 bit. This can be usefull if you use a custion .INI file which lists only a few patches. -Mxxx Set music master volume (relative to digital volume). xxx=1 to 100. xxx=90 is the default. -Iname Specify a different .INI file (instead of PATCHES.INI). 'name' can just be a file name, or a complete DOS pathname. -Q Disables the screen output. 4.0.0 ***************** CHAPTER 4. - REVISION HISTORY ******************** 94/01/20 Corrected a bug in proccessing of text files. This would cause LOADPATS to lock up with certain .INI files. 94/01/21 Pressing Ctrl-C while running LOADPATS will no longer leave the system unstable (irq's were not getting unhooked). AIL_detect_device will now use the ULTRASND environment variable to get the UltraSound base address. Previously it would probe for the base address, causing problems with other hardware devices. Improved documentation. 94/01/25 Drivers are now backward compatible with the older DLLLOAD.C, and hence can be used in place of A32MT32.DLL and A32SBDG.DLL etc. 94/01/31 LOADPATS: Will no longer exit to DOS on CTRL-C. Will now use (ULTRADIR)\MIDI if the PatchDir field in ULTRASND.INI is invalid. Aborts if it encounters an old patch. Corrected a major bug in the cross-mapping of the patches. This was causing divide by zero errors. Added -L switch to enable UltraSound line in. END OF READMEDownload Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
