Rana Systems’ Enhancements for Apple’s Apple II
DOS 3.3 allow automatic accessing of 4 drives
from the Rana Elite Controller Card and the
additional capacity of the Elite Disk Drives.
The Controller Card is capable of addressing any
combination of Apple Disk II and Rana Elite
Series Drives. The PROFILE program sets up DOS
(Disk Operating System) to recognize which
drives are Rana Elite Drives and which are Apple
Disk LI drives. The seek rate can also be
increased by the PROFILE program to take advant-
age of the increased speed of Rana drives.
The enhancements made by the ENHANCE utility
only apply to a master DOS diskette. Non-master
diskettes (slave diskettes) are what are created
when the DOS “INIT” command is used to initial-

placed on such a diskette is not ENHANCE-able.
Even though a diskette may say it is a master”
when it is booted, it may not actually be one.
The program which says the diskette is a master
is completely independent of the DOS itself, and
can be copied br saved (by an “INIT’ command,
for instance) onto a slave DOS diskette.
Those DOS 3.3 diskettes supplied directly from
Apple are all master DOS diskettes. In addi-
tion, any diskette which is a copy of an Apple
DOS 3.3 distribution diskette, made using the
Apple COPY or COPYA utility will also be a
system master diskette. These instructions will
assume you are using your original DOS 3.3 dis-
tribution diskette from Apple; but if you’ve
