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

["Peter Peltonen" <peter.peltonen@xxxxxxxxx>]

I have (almost) now solved my issues with Xen not resolving all RAM of
Supermicro server.

As grub patching seemed a bit too much work, I went straight ahead to
flashing the BIOS.

Everything else went just fine except one strange thing: Before the
upgrade BIOS reported 5904M of RAM. After the upgrade it reported only
5360M.

After BIOS upgrade I booted to 64bit CentOS5. To my disappointment the
system still saw only  3,2G of RAM.

But I did not give up :)

I thought that if the problem was with grub, maybe some older version
would work. So I installed 64bit CentOS 4.5 and installed Xen 3.10 to
it from the binaries Xensource provides. And this is what I can now
see on my server's screen after issuing `xm dmesg`:

(XEN) System RAM: 5343MB (5471676kB)

So the problem was with grub I think and I probably just hurt myself
by flashing the BIOS as I lost a few hundres of megabytes of memory.
But at least we made this much progress.

Cheers,
Peter
