| 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 |
