Installing Hard Disk Drives
Ll
It is recommended that a
X-bit,
AT-type hard disk
controller be used if you are installing a drive that cannot
use the embedded IDE interface. If you install a non-IDE
hard disk drive and controller card, you need to use the
SETUP program to disable the built-in IDE hard disk drive
interface.

When installing a hard disk drive, see the hard disk drive
type tables on page 7 and use the SETUP program to select
the correct type number for the drive. You can select a
type number that matches the parameters for the drive or
a type number with parameters having lesser values, as
long as they do not exceed the maximum capacity (in MB)
of the drive. If there is no match for the drive, you can
select a user-defined drive type (48 or 49) and enter the
drive’s exact parameters.
Software Problems
Ll
When installing a copy-protected software package, first
try the installation at high speed. If this does not work
properly, select low speed by pressing the
Ctrl
and
Alt
keys
and the
-
key on the numeric keypad simultaneously. Try
loading the program at low speed and then switching to
high speed, if possible.
Cl
When using a software package that uses a key disk as its
copy-protection method, try loading it at high speed. If
this does not work, load it at low speed.
Password
Make sure that you do not forget the password you set up. If
you do, you must disable it by setting jumper J7 on the main
system board to the ON position.
If you set J7 to ON, however, CMOS RAM returns to the
factory settings and you need to run the SETUP program to
enter your system configuration again.
Booting Sequence
If you cannot boot the computer from the hard disk drive,
make sure the booting sequence in the SETUP program is set
to A, C. Then boot the computer from a system diskette in
drive A.
