If the system BIOS is a PnP one there is a good chance that ESSCFG will completely ignore user settings for IRQ/DMA/MPU and will display a message about adjusting them via the BIOS - something that most of the times is not even possible. In this case download UNISOUND and edit ESS.BAT to disable ESSCFG and enable it. You will still need to use ESSVOL in order to enable AuxB output - this is used by the WaveTable header on the board. |

A great replacement driver by JazeFox. Please read the included unisound.txt for more info. /x3D0 switch makes sure that the ESS 1869 "3D sound enhancements" are OFF If you are using the wavetable header you will also need to run ESSVOL to adjust volume for AuxB input as Unisound changes it to 0 (mute).

In most systems we tested the native ESS1869 VXD drivers have buggy DOS support under Windows98/SE (at least) which result in many games not being able to detect Adlib/FM capabilities. Use these modded drivers to revert the main driver file to the ESS1868 version which does not exhibit this bug. There is no downside other than "3D sound enhancement" functions also getting disabled. Both VXD driver versions use a SETUP program to easily install them and will remove any existing drivers prior to installation making changing between versions easy. |
