An interesting wrinkle--controller boots fixed drives but not removable ones? Well anyhow, looks like I need to validate that my config can enumerate three drives under ANY OS--especially these particular drives. Any suggestions anyone how I could test this out under MSDOS, for example? Anyhow, it does seem to me the ability to boot off a removable drive would be a very desirable alternative to partitioning or dedicated hard drives for certain purposes. For example, I've got a co-worker that is thinking of installing FreeBSD on a system that she uses for home office running Win95. I'd like to to be able to steer her toward a removable drive solution rather than partitioning. 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)? If so what drive and controllercombination? Such info might be useful to include on the hardware compatibility list. I'm getting swamped with questions@FreeBSD.ORG mail so I plan to unsubscribe in a day or so. Anyone that responds to this, I'd appreciate your copying directly to me. Cheers!
