Comment 4 for bug 1453593

at #3 - bios upgrade:

considering the fact that such an upgrade is a sensitive matter, I feel that the suggested procedures are somewhat risky because not being really transparent to me.

On the other hand, I have a virtual win7 machine (32bit install) (under virtualbox) at my disposal.
Maybe, you could suggest a simple, more transparent way for a successful BIOS upgrade by using this virtual machine?
