Hi all, I was intrigued by this nice thread. I have access to an old Fujitsu Siemens Lifebook S6120D lying around in an office. I will try to buy new processor, and to replace the original, which is Pentium M 1.6Mhz. With this one, starting the Windows 8 install CD results in an error message, about the PAE incompatibility. The notebook has 2GB RAM, two pieces of 1GB each: one piece at 400Mhz (PC3200) and one piece at 266Mhz (PC2700). I will post a feedback. of course. What I am unsure, is whether BIOS needs a mod or not. It is with the latest possible version (1.26). Aside of this, the notebook is not able to recognize bigger than 120GB Hard Drive. Can someone give a hand on the BIOS questions, please ? I have uploaded here the version of this BIOS (1.26), in three different flavors, (as per the official support site) BUP, ISO and EXE: mega.co.nz/#!hEVVjSKA!k5j6o9ZoYdkDAu9yHLWRjjLTFTv1XxOxzpXnv2G8JZI (It is a Phoenix make) I also read the javamocha2000 post, in the D600 CPU upgrade thread, so I shall look for the Intel Pentium M 725A processor, which is stated there to support PAE. TNX for support !
