audio device buffer underflowed?? HELP!

[chagos]

i just bought a new digirack, and i am on a deadline thats coming up in 2 days.

i tried to record one midi and audio track to pro tools, and i get this error: the audio device buffer underflowed(-6085)

now i know my firewire drive is supported because its got the oxford chipset and worked with my digi 001 just fine.
i checked my mac out, and it is also supported on the digi site (dual 867MHz G4 OS x.3.7)

I decreased my H/W buffer size like it told me to, and I still cannot record one single stereo track!

please help me! i cannot figure out what i might be doing wrong. and i've got a deadline in less than 2 days.

has no one else had this problem?
my computer is even supported!

i've been to the answerbase, and the answwrs there do not seem to deal with my particlular computer, which is suppose to be compatible.

i found the solution, just check out the post in post production.
it seems that even though my computer is supported, getting a firewire card solves the problem.

thanks
