1 | Documentation for the ESS1868F AudioDrive PnP sound card | ||
2 | |||
3 | The ESS1868 sound card is a PnP ESS1688-compatible 16-bit sound card. | ||
4 | |||
5 | It should be automatically detected by the Linux Kernel isapnp support when you | ||
6 | load 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 | |||
18 | NOTE: this is only needed when not using the kernel isapnp support! | ||
19 | |||
20 | For configuring the sound card's I/O addresses, IRQ and DMA, here is a | ||
21 | sample 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 *) | ||
35 | at the beginning and the | ||
36 | (WAITFORKEY) | ||
37 | at the end.) | ||
38 | |||
39 | In this setup, the main card I/O is 0x0220, FM synthesizer is 0x0388, and | ||
40 | the MPU-401 MIDI port is located at 0x0330. IRQ is IRQ 5, DMA is channel 1. | ||
41 | |||
42 | After configuring the sound card via isapnp, to use the card you must load | ||
43 | the 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 | |||
54 | opl3 is the FM synthesizer | ||
55 | /sbin/insmod opl3 io=0x388 | ||
