Re: [Xen-devel] X86_64 and 4GB RAM using Flat Memory Model?

["John Hannfield" <hal9020@xxxxxxxxx>]

Hi Kier,

OK, I have updated my grub to the latest available from Debian stable/etch.
When I access grub at the boot menu, it displays the following for
'displaymem'

grub> displaymem
EISA Memory BIOS Interface is present
Address Map BIOS Interface is present
Lower memory: 631K, Upper memory (to first chipset hole): 3144640K

So this is a bit better. More than 4 MB.
However it does not show any address ranges below that, like it does on
when booted in to the OS.

Any further ideas?

Normal debian etch booting on same machine sees all 4GB, using the same
grub. But I guess it doesn't get the memory map from grub?  If I know the memory
map from the vanilla linux boot, can I provide this another way to xen?
