That is often a trademark sign that the video card is an NVidia, and that you are using the NVidia driver, which ties up the IRQ for as long as 100 milliseconds at a time and makes the machine worthless for LCNC purposes. Using the vesa driver, which limits the resolution, might work and would confirm my SWAG* about the video card holding you for ransom While I have one in this box, I'm only running the sim here, and using the nouveau driver which although the graphics are gaming speeds, plays movie and news story's off the net well. But the sim still reports servo-thread times above a millisecond in the terminal its launched from. Not enough to affect the sim, but this old Asus M2N-SLI Deluxe couldn't get past a latency test on a bet, its just not suitable for the real thing. Good board otherwise or I would have binned it long ago. > i'm also having problems with the graphics card not wishing to work in > graphics mode , only in software , so giving an even higher cpu load > this is on an amd64 ( using i386 os ) motherboard that up to now has > ran Linuxcnc for the last 3 years . I run my older machines, a 7x12 lathe (ball screws and steppers) and the small HF toy mill (ball screws, bigger tables and steppers) on atom boxes, the toy mill still using software stepping but a 5i25 card would speed up its rapids, currently limited by a 27 u-s base thread, and only a 28 volt supply for the steppers. My newer mill I've been talking about, a grizzly G0704 has higher voltage and is currently being run by an off-lease Dell 745. With a 5i25, its on-board graphics are more than adequate for the job. These are available locally with 4Gb of ram, sans HD so he gets to keep the winderz license, at $140. A small commodity HD, a 5i25 card, and its all set. Those D-525-MW atom boards that were nearly ideal for an economical software step setup, have been discontinued for about 3 years, and the last one I saw on ebay was selling for 4x the boxed OEM price. So this Dell 745 setup looks quite attractive in comparison. I might pay to visit your local computer guy and see whats there as there were a kajillion of those Dells sold to businesses that replace them as they are amortized on the p & l tax forms. No PATA sockets on these mobo's though, all SATA. A floppy and a DVD r/w seem to be std equipment. So a LCNC install is a 20 minute or less job.
