#Sound blaster software conflict windows

If you have Win9x installed CTCM always reads the CTPNP.CFG from the Windows directory. Then the file can be set to Read-Only with ATTRIB +R CTPNP.CFG. To make sure that CTCM always tries the same resource settings the desired resource configuration can be entered in CTPNP.CFG. For games that have fixed configuration values entered in the game setup this is impractical. However in case something is changed in the computer it may happen that CTCM finds different available resources and sets a configuration that is different from the previous.

When it finds available resources it prints them out and the BLASTER variable is set. The pragmatic approach is to call CTCM.EXE from the command line. On success it leaves the card configured, writes the current configuration back to CTPNP.CFG and sets the BLASTER environment variable. If resources are conflicting with other devices CTCM tries different settings. (if CTCM is not set then it uses C:\) It reads the configuration profile from CTPNP.CFG and tries to set the card to this resources. When CTCM.EXE is run it looks in the path set in the CTCM environment variable after the file CTPNP.CFG. There is also a text file with the name CTPNP.CFG where resource settings are contained.

When you download the DOS drivers for PnP Sound Blasters you will find the two tools CTCM.EXE and CTCU.EXE. The configuration works slightly different here.

C:\SB16\DIAGNOSE /S Diagnose takes the desired setting from the BLASTER variable and configures the cards resourcesįully ISA-PnP capable Sound Blasters do not have jumpers for base port resources such as this Sound Blaster 16.

SET BLASTER=A220 I5 D1 H5 P330 T6 After A the jumpered address should follow.įor IRQ, DMA the desired resources should be entered.

For example Sound Blaster 16 is of this type.

Semi-PnP Sound Blasters have only jumpers for the base port with markings IOS0, IOS1.

C:\SB16\MIXERSET /P /Q setting up the cards volumes.

SET BLASTER=A220 I5 D1 H5 P330 T6 here the jumpered configuration values should be set.

The autoexec.bat lines are simple in this case: For example this Sound Blaster 16 is fully configured by jumpers. On earlier Sound Blasters the marking says DRQ (DMA) and IRQ. There exists IOS0, IOS1 to set the address as well as DASx (DMA low), DBSx (DMA high) and ISx (IRQ) exist.

port is set by jumpers and the remaining resources by software, I will call this semi-PnPĬards that are fully configured by jumpers can be identified by looking at the jumper block markings.

Regarding the full configuration three types of Sound Blaster cards have to be considered: Note that H and P do not appear for earlier Sound Blasters.įor a Sound Blaster AWE32 the line would like like this: With the 16 bit DMA set to 1 (also called High DMA) and external MIDI port at 330. a printer resulted in noise output.įor a Sound Blaster 16 a typical variable setting looks like this: For later Sound Blasters it was changed to IRQ 5 as 7 is also default for the LPT1 parallel port. For Sound Blaster 1.x the default IRQ is 7. This implies of course that the card is actually jumpered to Port 220, IRQ 5 and DMA 1. A typical environment variable setting looks like this:įor a Sound Blaster 2.x.

On early Sound Blasters until Pro 2 all resources are set by jumpers. Some applications read just the port address from the BLASTER variable and determine the IRQ and DMA by auto detection.

6 - Sound Blaster 16, also SB 32, AWE32/64, ViBRA.3 - Sound Blaster 2.x (8 bit mono, 44.1 kHz) or compatible.2 - Sound Blaster Pro (8 bit stereo, 22 kHz) or compatible.1 - Sound Blaster 1.x (8 bit mono, 22 kHz) or compatible.kkk - port of the EMU8000 chipset when using an SB 32/AWE32/64 card, typically 620.www - port for external MPU-401 and wavetable at the waveblaster connector, typically 330, 300.v - DMA for 16 bit transfers, typically 5, 7.z - DMA for 8 bit transfers, typically 1, 0, 3.xxx - I/O port address in hex, typically 220, 240 or 260.The BLASTER variable stores the information in the following scheme: When software uses Sound Blaster cards in DOS it usually reads resource information from the BLASTERĮnvironment variable.
