hi, i just put my hands on a couple of old indy r4000 (quite old) i installed so far a debian woody linux distro! amazing.. i'm wondering about the bunch of special features available on the indy, how much are supported? 1. audio hal2: i saw in the cvs.sgi.com kernel the OSS hal2.* files; what about the guenther alsa0.9 port? is it finished? what about iec958 spdif support? 2. isdn: there is a siemens isac-s chip (BTW i didn't see the hscx twin): is it supported now? it should be not to difficult to leverage the ia32-isdn hisax (passive) isac driver _if_ the hpc3 delivers the irq? what do you think about it? bye andrea venturi
