MITSUBISHI MF501C/MF504C FLEXIBLE DISK DRIVES
INSTALLATION GUIDE
1. Preparation prior to installation
(1) Option jumper settings:
The factory pre-settings of the option jumper plugs are shown in Fig. 1.
They are set to make the drive plug-in compatible to the IBM
PC~ pC-XT~
and
PC-AT~
(The MF504C is workable only with the
PC-AT~)
Therefore no
relocation of the jumper plugs is required for these and other fully compatible
computers.
.
If your IBM compatible computer requires a unique option setting, or your
computer is not IBM compatible, refer to Section 3 in this guide for appro-
priate settings.
(2) Removing the terminating resistor pack:
If your system has another 5
1/.1
inch flexible disk drive
installed,
remove the
terminating resistor pack from the drive connected to the middle connector
of the FDD controller signal cable. The terminator pack of the MF501C or
MF504C is located on the P.C. board as seen in Fig. 1.
If your other flexible disk drive is a 3.5 inch drive, always remove the termi-
nator pack from the MF501Cor MF504C.
