- 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
