Hy!

I'm running Xen on several systems and everything was ok,

I just got a new 2 x Dual core Xeon 5030 on an Intel S5000PAL with SAS drives and ESB2 chipset.

The CPUs are 64-bit, from what i read in the archives from xensource, it isn't possbile to load 32-bit kernel on guest if dom0 is 64-bit.

OK, then how can i compile Xen in order to see all 4GB of RAM (and not only 2396MB) while keeping 32-bit Dom0?

I tried the Highmem support for 4 GB and i still see only ~2GB, if i compile with 64GB option the system craches and boot-time with some PAE error.
