Dino, there's one other *potentially serious* matter if you're using Intel's Brookdale chipset.
I have a NetVista I'm trying to use, and I experienced the kind of latency problems you had, but I found drivers for the onboard video. See http://ubuntuguide.org/wiki/Ubuntu_dapper#How_to_install_Graphics_Driver_.28Intel.29 The NetVista I have only has two PCI slots, so I wanted to use onboard video and save a slot. After installing the driver, the reported latency was down at 11,000-20,000 or so most of the time. BUT I still wound up with a ridiculous-seeming .6 to .75 millisecond delay showing up _once a minute or so (!)_. This would mean, if I were doing software stepping, that once a minute terrible things might happen. Talk about *weird*. Then I found out about the SMI interrupt problem with Brookdale chipsets. Take a good look at http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingDapperSMIIssues . That page mentions there's a precompiled version of the change to RTAI available: http://wiki.linuxcnc.org/uploads/rtai_smi.ko I haven't followed the instructions yet but I am optimistic. -- Michael M.
