Above I mentioned qemu which was used to test a virtual machine with 486 CPU and 24MB memory.... testing again with 4MB works fine as well ... but with only 2MB of RAM the virtual machine just reboots after "Loading ROM image ... "

If I reduce iPXEs size by building intel.dsk (which only has Intel drivers instead of "all" drivers) then it works fine with only 2MB as well.

Anyway, RAM size is not the issue here, but there is a multitude of possible reasons, to many to mention them all

But, have you run memtest86+ on the machine to make sure it don't have any faulty ram?

Since the issue you are having is in the loader code itself I'm not sure what, if any, debug methods are available.

You might also try some older version of iPXE for example checking out the old 1.0.0 tag and see if that behaves differently (if it at all compiles that is)

Sorry not being able to help much more on this.
