Installation/Support Tips
Installing Diskette Drives
Make sure that the drive type has been correctly selected
P
in the SETUP program.
Make sure jumper J6 is set to position 1-2 to enable the
Cl
diskette drive controller.
Installing Hard Disk Drives
If you are installing a drive that cannot use the embedded
IDE interface, such as an ESDI hard disk drive, it is
recommended that you use a 16-bit, AT-type hard disk
controller. If you install a non-IDE hard disk drive and
controller card, you must set jumper J23 to position 2-3 to
disable the built-in IDE hard disk drive interface. Also be
sure to remove the hard disk drive ribbon connector from
the system board.
When installing a hard disk drive, see the hard disk drive
type table on page 7 and use the auto-sensing feature in
SETUP to select the correct type number for the drive. If
the auto-sensing feature does not produce a match for the
drive, you can define your own drive type by selecting
User as the type and entering the drive’s exact
parameters.
Software Problems
Cl
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 Ctrl Alt - (using the
numeric keypad). Try loading the program at low speed
and then switching to high speed, if possible.

this does not work, load it at low speed.
Booting Sequence
If you cannot boot the computer from the hard disk, make
sure the booting sequence in SETUP is set to
Then boot the computer from a system diskette in drive A.
Password
Make sure that you do not forget the password you set up. If
you do:
Disable the password by setting jumper CN3 on the main

system board to position 3-4.
Then turn the computer on and off again

A:
Installing Option Cards
If you are installing a video adapter card that doesn’t support
VGA, make sure you disable the built-in VGA by removing
jumpers J20 and J21.
Installing External Cache
When installing cache on a 486DX/50 or Pentium OverDrive
system, make sure you use a 15ns tag chip.
COM Port Assignment
If you want to assign COM1 as COM3, you must set jumper
J3 to position 2-3. If you want to assign COM2 as COM4, you
must set jumper J2 to position 2-3.
Parallel Port Operation
If you connect a scanner to the parallel port, set
Configuration to Disabled so you can change the
Printer Port Control option to PS2 mode (for
bidirectional operation). The default setting for the parallel
port is AT mode (for unidirectional operation).
