Paul, Thanks for the help. The motherboard is an Intel N440BX, it does have an onboard video card which I think is a Cirrus 4680? The processor is 600Mhz P3 and I have 256Mb of ram I increased the period to .00005 and was able to run the default generic.ini file, so I was quite pleased with the progress. When I set the period back to .000022 I froze again so that appears to be the problem. One thing I thought was interesting is that I had installed a vital systems servo card (the 4-Axis version) and using the vital.ini, I was able to run with the period set to .000022 without any problems. I guess this has something to do with the way the card is managing certain processes that would normally be handled by the motherboard? Anyway,I'm off to hook up some motors to see if I can make something move. I'll report back.

I'm very new to Linux but managed to successfully install BDI 4.38 a few days ago. I seem to be having trouble launching EMC however. The problem is that the system hangs when TK starts to load. I'm saying this based on what I'm reading on the script window as EMC is loading.
Once the system is hung, I'm unable to recover and must reboot. I'll mention that I don't seem to be having any other problems with the installed applications so I believe the problem relates to EMC and Tk.
This sounds very much like PERIOD being set too low for your computer. This parameter is defined in /usr/local/emc/emc.ini, or generic.ini, depending on which run script you use.. The value is set at a fairly conservative 0.000025 and should work with most 400MHz and faster computers. Even a P266 will run, but performance would be quite sluggish... There are one or two motherboards out there that just can not provide adequate performance due to inherant design problems - Generally, anything that uses shared main memory for onboard video, certain i845/855 chipsets, and Geode processors all have "issues". You could try increasing PERIOD to 0.00005 and see if avoids the freezing. Some additional information about your computer (make/model of motherboard, graphics card, etc) would help..
