Hi Debra

Please *don't* try to use the socket on the floppy cable. That's for another
floppy drive.

Does the cable to your 8.4 GB drive have another plug on it? If so, it's what
you want to use.

    About your CDROM drive: Where is that plugged in? If it's on the same
    cable as the 8.4 GB drive, you can move this CDROM onto a 40 pin cable
    of it's own (which would likely plug into a socket on the motherboard
    right next to where the hard drive cable now plugs in) in order to make
    room for the second hard drive. You might not have to worry about
    changing the jumper block (shunt) on the CDROM drive...I just learned
    yesterday that it is okay to slave a CDROM drive to nothing.

    Another choice is to plug the 1.6 GB hard drive into the second 40 pin
    cable (the one that has no hard drives on it) but then you must replace
    the jumper block (shunt) that you removed from the 1.6 GB drive.

This is correct ONLY if both hard drives are attached to the same 40 pin
cable. (I looked at the web page that you mentioned.)

No matter how you do this, you will need a second 40 pin hard drive cable,
one that is NOT longer than 18" and has two plugs near one end. If there
is not such a cable in your computer now, you'll need to go to a computer
store and get one. This should not be a problem.

The white power socket on the hard drive is next to the long 40 pin socket
(for the data cable which goes to the motherboard). Both sockets are on the
back of the drive. The power socket is shaped so that it won't accept a plug
the wrong way. The 40 pin socket is coded (at the center) so that the cable
won't be put in wrong. (Notice that one pin in the middle of the 40 is
missing.) If the data cable will go in either way, put it in so that the red
striped side is closest to the power socket. Plug the other end of the 40 pin
cable into the socket on the motherboard so that the red side of the cable is
on the side of pin 1 (usually stenciled in small letters on the circuit board
by the socket).


> PS.  Additional question...[about motherboard]


You will get better help from people if you can tell them what kind of
computer you have. This includes both the brand and type of processor (Intel
Pentium, Pentium II or Celeron, AMD K5, K6 or K6-2, Cyrix/IBM). The processor
you have is usually mentioned on screen when you turn the computer on. Many
list subscribers can tell you what brand and model motherboard model you have
if you tell us the long BIOS identifier number shown at the bottom of the
screen at startup. (Hit the Pause key to freeze the screen while you write
this number down.) It is unlikely that you have an Intel brand motherboard
because Intel usually doesn't use Award BIOS'. (Many manufacturers other than
Intel still use Intel brand support chips on their motherboards.) By the way,
Award BIOS' are arguably the best made. Few (if any) Intel boards include
6 memory slots.

Bill
