AG, Well I'm sorry I don't have the DDO answer, but I can tell you what I did when I had the same problem. My ThinkPad 600 BIOS also is limited to seeing about 8GB of my replacement 20GB hard drive. So I put Win95 in the first 7.5GB, then FreeBSD after that. As long as the root partition of FreeBSD is fully before cylinder 1024 (guaranteeing BIOS can do its boot things) everyone is happy. This solution doesn't require DDO or any other BIOS tricks. I use the FreeBSD MBR. I'm limited to 7.5GB for Windows and the rest for FreeBSD, but that is not too bad.
