J5 Jumper Funtion Description (* indicates default)
──────────────────────────────────────────────────────
A B
OFF OFF Drive is the slave (Drive 1).
OFF ON Drive is the master (Drive 0) with slave (Drive 1) present.
ON* OFF Drive is the master (Drive 0).
C
ON* DASP- is brought into drive through I/O pin 39
OFF DASP- is not used and is not connected to drive. I/O cable
pin 39 may be used for spindle synch if jumper H is
installed.
D
ON* No spindle synch reference is used. See also J6 position
R, which duplicates the function of this jumper. Either J5
D or J6 R may be jumpered to signify no synch spindle
reference is used.
OFF Spindle synch reference signal cable may be plugged onto
this jumper, J6 R or spinle synch ref may be taken from I/O
cable pin 28 (if jumper J installed) or pin 39 (if jumper H
installed).
E
ON I/O connector J1 pin 28 is used for Cable Select function.
Jumper F must also be installed to implement cable select.
OFF J1 pin 28 not used for Cable Select function.
F
ON Cable select option enabled. Jumper E must also be
installed to enable cable select.
OFF Cable select option not enabled.
G
ON Optional feature #1 enabled
OFF Optional feature #1 not enabled
H
ON Spindle synch reference signal is on I/O connector J1 pin 39.
OFF Spindle synch reference signal is not on J1 pin 39.
J
ON Spindle synch reference signal is on I/O connector J1 pin 28.
OFF Spindle synch reference signal is not on J1 pin 28.
J6 Jumper Funtion Description (2x2 jumper block)
-------------------------------------------------
L Remote LED cable connection (Not a jumper position). Do not
install a jumper if remote LED cable is not plugged here.
R
ON No spindle synch reference is used. See also J5 posistion
D, which duplicates the function of this jumper position.
Either J5D or J6 R may be used to signify no spindle synch
reference is used.
OFF Spindle sync reference signal cable may be plugged into
this jumper position, J5 D or the spindle synch reference
may be taken from I/O cable pin 28 (if jumper J installed)
or pin 39 (if jumper H installed).

* MAY REQUIRE FORMATTING AND PARTITIONING SOFTWARE. ALSO, CHECK TO
SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE" DRIVE TYPE
AVAILABLE. (see below)
Possible translation: 1024 cyl, 16 heads, 63 sectors = 528,482,304
Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
Already low-level formatted at the factory.
Since a User-definable or Custom translation geometry may be used, it
is imperative that the values be written down and kept with your
permanent records for retrieval in the event of CMOS battery failure.
