I have been following this topic with some interest as I am trying to run 
NetBSD from a Jaz cartridge and have a few questions.  Does all of what has 
been said here apply to Jaz carts. too?  I used Silverlining to partition 
the cartridge and now have some minor conflicts similar to those 
described here.  Also, the partitioning software will allow me to install 
the Silverlining driver on the Driver_43 partition.  How will the disk 
drivers on the Driver and Driver_43 partitions interact?  Thanks for the 
help.
