Documentation for the ESS1868F AudioDrive PnP sound card
|
|
|
|
The ESS1868 sound card is a PnP ESS1688-compatible 16-bit sound card.
|
|
|
|
It should be automatically detected by the Linux Kernel isapnp support when you
|
|
load the sb.o module. Otherwise you should take care of:
|
|
|
|
* 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.
|
|
|
|
|
|
NOTE: this is only needed when not using the kernel isapnp support!
|
|
|
|
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/modprobe 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
|
|
/sbin/insmod opl3 io=0x388
