My first post too: I have a Samung Notebook M40, and the windows7 upgrade advisor indicated I can upgrade to win7. However, apparently the phoenix bios that came with the notebook is not ACPI compliant (?)... I have downloaded presumably a new bios for win/2000/XP which I doubt will work. I wonder if anyone can advise whether there is a new bios from Phoenix that will allow me to load Windows 7? The current bios is supposed to be Samsung NM40 notebook SM40 System BIOS/MICOM Ver 03JK for Win 2000. Many many thanks.
