Ok, i managed to run simple test bootsector code on the 3 drives. The nice thing about standards is that there are so many to choose from

I'm working on a new version of the installer that will enable to "install" MenuetOS to USB drives as the majority of PC's bought after 1999 will have at least some sort of support for USB-booting.

Don't expect anything soon tough .

edit:
Ok, the reason for the 4GB disk showing up as a HD: it had a partition table. That's 2 disks that i can write to with an easy "image dump".
