Re: [Xen-devel] Unable to start PAE Mini-OS from 0x0

I am trying to start PAE Mini-OS from 0x0 so that I can get access to

when it tries to pin the L3 table with the following error below.
Further more, I am not able to bring up Mini-OS from any other address
other than 0xc0000000.
Is there a restriction on this in i386 PAE? Could someone please
explain
why?
Xen absolutely requires that the 4th PAE pgdir slot is filled as Xen
hijacks entries in the pmd to map itself. In fact the builder should
probably simply allocate 4 pmd pages always, and always fill all 4
slots of the top-level pgdir when running on PAE.
