NOTE: Users of QEMM from Quarterdeck who are using the LOADHI.SYS feature to locate device drivers into high memory areas may, in very rare instances, experience a lock-up when exiting this demo. If this problem occurs, it can be avoided in the future by adding the option NOVIDEORAM to the QEMM statement in the CONFIG.SYS file; consult your QEMM manual for more information.
