+Documentation for the ESS1868F AudioDrive PnP sound card
+
+The ESS1868 Sound card is a PnP ESS1688 compatible 16-bit sound card.
+
+Notes about configuring the sound card:
+
+  *  The ESS1868 does not allow use of a 16-bit DMA, thus DMA 0, 1, 2, and 3
+     may only be used.
+
+  *  isapnptools version 1.14 does work with ESS1868.  Earlier versions might
+     not.
+  
+  *  Sound support MUST be compiled as MODULES, not statically linked
+     into the kernel.
+  
+For configuring the sound card's I/O addresses, IRQ and DMA, here is a
+sample copy of the isapnp.conf directives regarding the ESS1868:
+
+(CONFIGURE ESS1868/-1 (LD 1
+(IO 0 (BASE 0x0220))
+(IO 1 (BASE 0x0388))
+(IO 2 (BASE 0x0330))
+(DMA 0 (CHANNEL 1))
+(INT 0 (IRQ 5 (MODE +E)))
+(ACT Y)
+))
+
+(for a full working isapnp.conf file, remember the
+(ISOLATE)
+(IDENTIFY *)
+at the beginning and the
+(WAITFORKEY)
+at the end.)
+
+In this setup, the main card I/O is 0x0220, FM synthesizer is 0x0388, and
+the MPU-401 MIDI port is located at 0x0330.  IRQ is IRQ 5, DMA is channel 1.
+
+After configuring the sound card via isapnp, to use the card you must load
+the sound modules with the proper I/O information.  Here is my setup:
+
+# ESS1868F AudioDrive initialization
+
+/sbin/insmod sound
+/sbin/insmod uart401
+/sbin/insmod sb io=0x220 irq=5 dma=1 dma16=-1
+/sbin/insmod mpu401 io=0x330
+/sbin/insmod opl3 io=0x388
+/sbin/insmod v_midi
+
+opl3 is the FM synthesizer--I have not tried the SoftOSS wavetable
+synthesizer yet, but I assume it would work as well.  Also, doing:
+/sbin/insmod opl3
+/sbin/insmod adlib_card io=0x388
+works, but I believe the sound quality is a bit distorted when playing MIDI
+files.
+
+When using the above setup, my /proc/sound gives the following:
+
+OSS/Free:3.8s2++-971130
