-
- 1.0.0 ************* CHAPTER 1. - WHAT ARE THESE DRIVERS? *****************
-
- This package contains 'IBM Audio Interface Library for 32-bit DOS' (AIL/32)
- drivers for the Gravis UltraSound card. 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.
