x86 VS X64 Boot Image

I am trying to PXE boot a x86 machine, but it keeps trying to download the x64 boot image. I do have a mixture of x86 and x64. When the machine does download it tries to load and gives me an error about the wrong architecture...which is obvious because its a x86 trying to use a x64 boot image. How can I get the x86 to boot first...?...and will the x64 machine be able to use the x86...reboot and then download the correct boot image?
 
Thanks,

Configure the task sequences to only use x86 boot images. You can deploy x64 OS Image Packages even with a x86 boot image.

How can i make the PXE boot use the x86 as the default? THese are unknown machines, and i do have it designated in the task sequences which boot image to use...?? Any other suggestions?

Configure all task sequences to use the same x86 boot image, then PXE will use that one too.

I am new to SCCM....update all task sequences for that collection...being that it could possiblly be an unknown machine...i would have update every task sequence I have on my server to run x86 by default?

Okay, all my task sequences are set to use x86 by default...if these are uknown machines how will it know which boot image to use before it boots up to the task sequence?

The Task Sequence you advertised to the all unknown computers collection will have a boot image assoicated with it.
