Did you try using the rtirq script? You can find it on my home server, here http://www.rncbc.org/jack/rtirq-20070101.tar.gz I guess you can follow the instructions found on Florian's web page, and specific for your firewire setup (e.g. substitute "usb" by "ohci1394" on RTIRQ_NAME_LIST configuration setting). Ah, installation assumes a LSB distro and it probably needs change for your particular case. Feel free to ask if you get puzzled :) Cheers. -- rncbc aka Rui Nuno Capela rncbc@xxxxxxxxx
