Well in general I would say that using an x86 PC to do real time can't be done. Most x86 PCs use SMI, which destroys any hope of actually getting real time to provide any real response time promises. Now if you happen to have a PC that doesn't use SMI, or can have it disabled, then you can get real time. On things that are not PCs this is pretty much never a problem. There are some server vendors that provide information on turning off SMI because they have customers that want to run real time software on the machine. -- Len Sorensen _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
