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.

0When 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.
