It's not APIC, but LAPIC (Local APIC) that's the troublesome thingie. There are some (older?) BIOS'es that apparently don't enable it by default, so the user has to enable lapic at boot time (kernel param).
There have been quite a few messages how to fix this. But here it goes again: in /etc/default/grub, change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash lapic" and then run update-grub and reboot This only works if your system _does_ have an LAPIC. If you get the error message: [ 0.080250] Local APIC not detected. Using dummy APIC emulation. then you are out of luck, and you need a non-SMP RTAI install (hardy 8.04 for example).

I did try switching the APIC option in within my BIOS and I came up with a whole different set of errors, that said about the same thing. the out put ended with: RTAI[hal]:ERROR, LOCAL APIC CONFIGURED BUT NOT AVAILABLE/ENABLED Yesterday, I did some experimenting and a good bit of google research and one promising thing i found was this site: http://www.network-crawler.de/index.php/RTAI --which notes that if i get this error, then I will have to recompile. I have not idea what exactly i would recompile or how to do it, so please, if anyone knows, spell it out to me (i am really bad at Linux stuff). The computer that I am trying to install 10.04 onto is a neoware e100 thin client, with a VIA processor. Although it is x86 compliant, some earlier versions were made without support for APIC. This can be found by typing $ 'cat /proc/cpuinfo' and looking at the flags section. Well, lucky me, my processor does not support APIC, however my BIOS does not seem to know (or care). I am pretty sure that no APIC support on the process is my issue here, and this has absolutely nothing to do with 10.04. --Moderators, if you want to two and put in a new thread, feel free. -- So, at this point I have two questions: 1 - Does EMC2 require APIC support to run ? 2 - How would I go about configuring EMC2 to run with out APIC support ? Any help is greatly appreciated!!
