Re: [Xen-users] Xen-Kernel detects just 3.2GB Ram on a 64Bit Debian

[Stephan Seitz <s.seitz@xxxxxxxxxxxx>]

Hi Roman,

We had similar problems with recent Supermicro Boards after installing
huge amounts of RAM.
The problems disappeared on all machines after we made BIOS updates.
Only issue was to find the right BIOS image, since Supermicro offered
a bunch of images labelled with the same version but with different
release dates.

Greetings

Stephan
