Yup. I confirmed it the other day -- the Adaptec 2940 series can be taught to treat removables as bootable media.

I think this is all happening before the OS even sees daylight, so I don't know if having a DOS partition out there would help things. > Does anyone out there have boot of removables working for ANY removable drive, > even IDE on the second enumerated drive (e.g., Jaz, SyJet, SparQ)?
