Installing the Motherboard 2-11
User’s Manual
♦Two hard disks can be connected to each
connector:
The first HDD is referred to as the “Master”
and the second HDD is referred to as the
“Slave”.
♦For performance issues, we strongly suggest
not to install CD-ROM drive on the same
IDE channel as a hard disk, or the system
performance on this channel may drop (for
how much is depending on your CD-ROM
drive performance).
Note: The Master or Slave status of the hard
disk is set on the hard disk itself. Please
refer to the hard disk drive user’s manual.
Note: A red mark on a wire typically
designates the location of pin 1. You need to
align the wire pin 1 to the IDE connector pin
1, then insert the wire connector into the
IDE connector.
How to install the Ultra ATA/66 Cable
Assembly:
Figure 2-8. How to connect an ATA/66 cable
to the Motherboard
'The BLUE connector MUST be plugged into
the motherboard or your system will not
work.
'Each connector on the Ultra ATA/66 cable
assembly has a small polarization tab
centrally located on the body of the plastic.
This fits into the matching slot on the mating
plugs on the motherboard and the drives, thus
assuring positive mating (pin #1 to pin #1)
'The red line on the cable should be aligned
with pin #1. On the drives this will result in
the red line facing the power connector.
Attach the BLUE connector to the
appropriate 40-pin IDE plug on the
motherboard.
'Attach the BLACK connector to the mating
plug on the master hard drive. Attach the
GREY connector to the mating plug on the
slave drive (secondary hard drive, CD-ROM,
or tape drive). Please refer figure 2-8.
Figure 2-9. SE6 back panel connectors
Figure 2-9 shows the SE6 back panel connectors.
These connectors are for connection to outside
devices to the motherboard. We will describe
which devices will attach to these connectors
below.
(18) KM1 Lower: PS/2 Keyboard Connector
Attach a PS/2 keyboard connector to this 6-pin
Din-connector. If you use an AT keyboard, you
can go to a computer store to purchase an AT to
ATX converter adapter. You can then connect
your AT keyboard to this connector. We suggest
you use a PS/2 keyboard for best compatibility.
(19) KM1 Upper: PS/2 Mouse Connector
Attach a PS/2 mouse to this 6-pin Din-
connector.
(20) USB Port Connectors
This motherboard provides two USB ports.
Attach the USB connector from the individual
device to these connectors.
You can attach USB devices such as a scanner,
digital speakers, monitor, mouse, keyboard, hub,
digital camera, joystick etc. to one of each of the
USB connectors. You must make sure your
operating system supports this feature and you
may need to install an additional driver for
individual devices. Please refer to your device
user’s manual for detailed information.
