Got this in the mail and thought it would be of general interest.
In case you missed it, this is a response to my article on the 3.5"
DS Epson drive upgrade for the SF354.  There is a problem with the
non-boot drive (B:) not being recognized by the system unless a disk
(even a blank one) is in it.

OK, any ideas?  How about just shorting out the disk in
position switch? :-)
