However, going for your 2nd option (tweaked EFI disk label) are there any pointers on how to achieve it? I tried using rmformat (on a 64-bit OpenSolaris), gparted with GPT partition type (on Ubuntu 9.04, 32-bit) and Disk Utility with GUID partiion table (on Mac OS X Leopard), but all of these utilities allow only a "label" and nothing more. As you point out, creating a small partition inside the partition table does not solve the problem. Appreciate your help, Vassilis
