iPXE fails to boot anything

For the most part, your menu seems to be correct. You need to move the kernel command line parameter "iso" onto the "kernel" line instead of the "initrd" line, and you might want a "|| goto failed" at the end of the "choose" command.

Other than that I might be inclined to think your machine has a hardware problem. Have you thoroughly tested it with memtest and breakin? Does it come out clean?

FYI: There is also a version of memtest86 that is compiled as a linux kernel (bzimage) which can run directly from a "kernel" line, no need to use memdisk.

You might also try just "sanboot http://192.168.252.1/PXE/iso/atih11.iso" instead of using memdisk and see how that works instead.

And finally, if you're using undionly.kpxe to boot, you might have better luck with ipxe.pxe (which uses iPXE-provided drivers for the hardware in question instead of vendor-provided drivers).
