Booting Windows from a PS2 USB formatted drive
Since this this was considered to be impossible, I figured out how to do it. This is a fairly complicated issue, but the short story is that I first formatted the drive as a PS2 USB drive (I used a 320GB WD), and applied a bootsector using a command line tool found on the Windows Vista installation DVD, in the directory "BOOT", called bootect.exe. Query it for it's switches. And since this is a Vista thing, it makes Vista "bootmonger" and Windows XP bootsectors on just about anything, even fat partitions, nt52 or nt60, vista. I'm not sure how usefull this is, but I remember that this subject came up a long time ago. I'm not sure, exactly, if anyone else would find it usefull, I copied an installation of Windows XP to that drive, that I specially prepared to run from a USB drive (and from just about any x86 machine it should "awake" on), without crashing, you have to have the drive installed on the IDE bus (inside) of your pc to install on, otherwise, this is still really hard, and not very practical, but I can, now, in fact, boot Windows XP, and play PS2 games off the same USB drive, so it can be done, and I can elaborate, if anyone cares.
Some may wonder why I bothered to do this, well, because I knew I could, so I just had to. What can I say, I'm constructing a home-built, back yard gas turbine (yes, a jet) from a turbocharger unit recycled from an old diesel truck. Same reason.
