Ditch isapnp and those config files. If using Red Hat, add "nopnp" to the kernel command line. Configure your kernel (2.4.xx or 2.5.xx) to handle ISA PnP by itself.

Blame your motherboard. Many 486 motherboards have trouble with DMA. I've had similar problems with a real SoundBlaster16 and a "486". (IBM BlueLightning 486SLC2-66, Intel 486SX-25, and Intel DX4-75 OverDrive)
DOS DOOM played in DOS --> crash DOS DOOM in an OS/2 window --> OK Linux with 8-bit sounds --> OK Linux with 16-bit sounds --> crash
Forget about sound, junk the box, or use OS/2. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
