But I think it has a Trident 4DWave NX/DX compatible chip. The audio hardware is supported with snd_t4dwave(4) on i386. However AFAIK the hardware can't handle DMA addresses located above 1GB. Since sparc64 uses DVMA and if the DVMA address is higher than 1GB it wouldn't work at all. I don't know how Solaris handled this limitation but if there is a way that solves the issue we can easily support a bunch of old PCI audio hardware including SoundBlaster Live! -- Regards, Pyun YongHyeon
