Hi, Many years ago i used a RT-os, But when seeing you asking for videodrivers and vmware...... For real RT-applications, you should want to avoid unneeded IRQ's at all time: barebone, no graphics (but serial console), no virtualisation, no add-on hardware and as much as possible unneeded io on your mobo disabled. hw -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
