   1Documentation for the ESS1868F AudioDrive PnP sound card
   2
   3The ESS1868 sound card is a PnP ESS1688-compatible 16-bit sound card.
   4
   5It should be automatically detected by the Linux Kernel isapnp support when you
   6load the sb.o module. Otherwise you should take care of:
   7
   8  *  The ESS1868 does not allow use of a 16-bit DMA, thus DMA 0, 1, 2, and 3
   9     may only be used.
  10
  11  *  isapnptools version 1.14 does work with ESS1868.  Earlier versions might
  12     not.
  13
  14  *  Sound support MUST be compiled as MODULES, not statically linked
  15     into the kernel.
  16
  17
  18NOTE: this is only needed when not using the kernel isapnp support!
  19
  20For configuring the sound card's I/O addresses, IRQ and DMA, here is a
  21sample copy of the isapnp.conf directives regarding the ESS1868:
  22
  23(CONFIGURE ESS1868/-1 (LD 1
  24(IO 0 (BASE 0x0220))
  25(IO 1 (BASE 0x0388))
  26(IO 2 (BASE 0x0330))
  27(DMA 0 (CHANNEL 1))
  28(INT 0 (IRQ 5 (MODE +E)))
  29(ACT Y)
  30))
  31
  32(for a full working isapnp.conf file, remember the
  33(ISOLATE)
  34(IDENTIFY *)
  35at the beginning and the
  36(WAITFORKEY)
  37at the end.)
  38
  39In this setup, the main card I/O is 0x0220, FM synthesizer is 0x0388, and
  40the MPU-401 MIDI port is located at 0x0330.  IRQ is IRQ 5, DMA is channel 1.
  41
  42After configuring the sound card via isapnp, to use the card you must load
  43the sound modules with the proper I/O information.  Here is my setup:
  44
  45# ESS1868F AudioDrive initialization
  46
  47/sbin/modprobe sound
  48/sbin/insmod uart401
  49/sbin/insmod sb io=0x220 irq=5 dma=1 dma16=-1
  50/sbin/insmod mpu401 io=0x330
  51/sbin/insmod opl3 io=0x388
  52/sbin/insmod v_midi
  53
  54opl3 is the FM synthesizer
