I have been having problems mounting my zip drive and using disklabel on
it.  My zip drive is attached to an Adaptec 1510A scsi controller.  When
NetBSD boots it finds the zip drive at sd0.  Whenever I try to mount sd0 or
use disklabel on sd0 my computer goes into a state that only allows
keyboard input, but it does not process any input from the keyboard.  Does
anybody have an idea on how to solve this?
