Epson 2000 - Manual (Page 65)

This section includes steps for the following procedures:
Removing the mounting frames from the hard disk drive
(if necessary)
Installing the hard disk drive below the diskette drive in
the mounting bracket
Replacing the mounting bracket and drives in the computer
Connecting the drive cables.
If you have two hard disk drives, one must be configured as
the master (which contains your operating system), and the
other as the slave. Be sure to check the jumper settings on the
hard disk drive before you install it.
Also, you may need to know the number of cylinders, heads,
sectors, etc., if the hard disk drive auto-sensing feature in
SETUP is unable to correctly identify your drive. The hard disk
drive table used in the SETUP program is included in
Appendix A, along with a table of jumper settings for
high-capacity EPSON drives. If your drive is not listed or you
need more information, see the documentation that came with
your drive or contact the manufacturer.
