Simply plug in the BL A C K END of the Serial ATA cable into the motherboard Serial ATA
connector, and the other end(s) into the drive(s). Each standard Serial ATA cable has tw o
connectors. Both BLACK ENDS of the Serial ATA cable are the same that are used to connect
to drives or motherboard.
Floppy Drives
Attaching a floppy drive can be done in a similar manner to an IDE drive. See the diagram
below for an example of a floppy cable. Most of the current floppy drives on the market require
that the cable be installed with the colored stripe positioned next to the power connector. In
most cases, there will be a key pin on the cable which will force proper connection of the
cable.
The first floppy drive (commonly denoted
as
A :
) is usually attached to the end of
the cable with the twist in it. Drive B: is
usual ly connected to the second or third
connector in the cable (the second or
third connector after you install Drive
A:
).
Refer to your floppy drive’s installation
instructions (if available), or contact your
dealer if you are unsure about how to
attach the floppy drive(s). Remember,
you can only have 2 floppy drives
connected at any given time.
Below are some symptoms of incorrectly installed floppy drives. While they are minor and
installing them incorrectly doesn’t cause severe problems, it may cau se your system to freeze
or crash when trying to read and/or write to diskettes.
Symptoms of incorrectly installed floppy drives
Drive is not automatically detected
Usually caused by faulty cables, cables put in
backwards or a bad floppy drive or motherboard.
Try another floppy drive to verify the problem if
the cable is properly installed or try replacing the
actual cable. Also check to see if the onboard
floppy controller is enabled in the BIOS setup.
Drive Fail message at bootup
The cable, floppy driv e or motherboard may be
faulty. Try another drive or cable to verify.
Drive does not power on
Check power cable and cabling. Maybe a bad
power supply or drive cable problem.
Drive activity light is constantly on
Usually signifies that the cable on the dr ive is on
backwards, which is a common issue. Reverse
the cable at the floppy drive end and try again.
