Three Pre-installed DOS drivers for the most common ESS Audiodrive ISA Sound Cards.
They come with a bat file which can be copied into the autoexec.bat when desired. 

ES1688
Controller+Codec 16-bit 44KHz, Integr. OPL3 clone, MPU-401, joystick support, Half-Duplex, No hardware volume.
Card is already SB-Pro at A220 I7 D1 at boot. (contrary to ES1868).
Just need to enable MPU-401, and set it at 330h instead of 300h.

ES1868 (or ES1878)
Controller+Codec 16-bit 44KHz, Integr. OPL3 clone, MPU-401, PnP, dual joystick, Full-duplex, IDE.

ES1869
Controller+Codec 16-bit 48KHz, Integr. OPL3 clone, MPU-401, PnP, dual joystick, Full-duplex, IDE, Spatializer 3-D VBX.
Warning these files are named just like the ES1868 ones, but are slightly different!

All three tested to work OK.
