From what I read about the controller, it tries to keep load off the CPU by sending/reading as much data as possible from the main memory. Well, at least that's what it sounds like. Now, if they'de just make a hardware IDE controller with on-board SIMM or DIMM slots... heh.. What a mutant of a card that would be :) Gabe -- -------------------------------------------------------------------------------- Gabe Turner | X-President, UNIX Systems Administrator, | Assoc. for Computing Machinery U of M Supercomputing Institute for | Univerisity of Minnesota Digital Simulation and Advanced Computation | dopp at acm.cs.umn.edu "I'm gonna be a monkey.
