Don't assume the drives have sticktion just because they're not spinning. They don't start until the controller tells them to, and you're not far along enough yet in the boot process for that to have happened.

Of course, they could still be stuck. But I doubt it.

BTW the 8514/A outputs 256 colors at 1024x768 30Hz interlaced. You may have trouble finding a monitor that will sync to that.
