[SOLVED] VirtualBox, LTSP, “SMBus base address uninitialized – upgrade BIOS or use force_addr=0xaddr”

As I have mentioned in the previous post, I was experimenting with LTSP on my Ubuntu 10.04 Lucid Lynx Alpha installation. I set up ltsp client and then created a diskless VirtualBox Virtual Machine with Network Boot as First Boot Option. I tried to boot it and it an error came up. It said:

SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr

and just froze there.
Since I have Core 2 Duo, I set up two processors in the System>Processor. I just set it back to one processor and despite of the error, the LTSP server booted successfully.
