have only labview run on a computer at boot.

I was wondering if there is a way to boot directly into a VI at startup. I do not want to go into windows first, I just would like to see the bios do its thing, then my grpahical VI come up and be able to operae from there. Basicly Im working on a dedicated system that for some reason if it is off, or reboots, i need to get that VI up and running asap. As well this system is ONLY going to be useing this one VI, nothing else, so therefore there is no need for anyhting else on it. Ive heard of realtime being able to do somthing like this, but does real time give you a display? or is it all in the background?

Thank you very much!

Your vi must run on some type of operating system. Therefore, the OS must load prior to the vi startup. The RT OS has a much faster startup time because there is a much lower overhead than Windows. The disadvantage is that the display must be done on a remote computer connected via Ethernet. You may be able to make Windows start more quickly by limiting the services which start up at boot time.

I would highly recommend that you include a UPS with your system if uptime is critical. This not only helps to eliminate downtime due to short power outages but allows for proper shutdown of the machine for longer power outages, thereby reducing the possibility of file corruption. If other factors in your process are causing a shutdown of your system I would inve
stigate how to eliminate this full shutdown.

thanks! What do you think would be one of the quickest loading windows out right now that would run LabView well? I def dont think XP, I was mabye leaning towards Windows 2000. Any suggestions?

My experience has been that XP loads rather quickly. However, its hard to tell since the XP is also usually on faster machines. If you'll set either XP or 2000 up so that a lot of the extraneous stuff aren't loaded then I doubt that there will be a lot of difference on the same machine.

alright, well luckily i have copys of each to try out first. Thanks!

You may also want to consider Windows XP Embedded. You can easily pick and choose which parts of the OS you require to be installed and you can customise its behaviour on a more finer level than Windows XP.
