Installing a Hard Disk Drive in the Internal Drive Bay
Your computer may have a hard disk drive already installed in
the internal drive bay. If not, you can install a l-inch high by
3½ inch wide drive in this bay.
Here you will find steps for the following procedures:
Removing the mounting frames from the hard disk drive
(if necessary)
Connecting the hard disk drive cables
Installing the hard disk drive under the mounting bracket
Installing the hard disk drive above the mounting bracket
Note
Be sure to check the jumper settings on the drive before you
install a hard disk drive. Also, you will need to know the
number of cylinders, heads, sectors, etc. to select the correct
drive type in the SETUP program. See the documentation
that came with your drive for this information.
Before you can install a hard disk drive, you need to remove
any option cards that may be blocking your access to the hard
disk drive area. Once you have installed the drive, replace any
option cards you removed. See Chapter 3 for instructions.
