Processor Chips
Hard Disk Drive Types
Support is provided for a future OverDrive processor.
The table below lists types of hard disk drives you can use in
the computer. Check this table and your hard disk manual to
find the correct type number(s) for the hard disk drive(s)
installed in the computer. You need to enter the type
number(s) when you set the hard disk drive configuration in
the SETUP program.
SIMM lnstallation
There are two SIMM sockets on the main system board. To
increase the amount of memory in the computer up to
128MB, you can install 36-bit, n-pin, gold-leaded, fast-page
mode SIMMs that operate at an access speed of 70 ns or
faster, with a capacity of lMB, 4MB, 16MB, or 64MB.
Had Disk Drive Types
The following table shows the possible SIMM configurations;
do not install memory in any other configuration. Make sure
that both SWIMS operate at the same speed. The computer
comes with 20MB of memory @MB soldered on the main
system board and one 16MB SIMM).

lnstallation/Support Tips
Power
The computer has an input voltage selection switch on the
back panel to select between 115 VAC, for USA and
Canadian use, and 230 VAC, for use in other countries.
Mouse and Keyboard
When connecting the mouse and keyboard to the computer,
be careful to plug them into the proper ports. Although the
ports are physically identical, they are not interchangeable,
and you may damage the main system board if you plug the
connectors into the wrong ports.
Installing Diskette Drives
Make sure that the drive type has been correctly selected in
the SETUP program.
Installing Hard Disk Drives (for DOS Use)
It is recommended that a 16-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.
See the hard disk drive type tables on pages 7 and 8 and
use the SETUP program to enter the correct type
number(s) for the hard disk drive(s) installed in the
computer. (Also be sure to use the SETUP program to set
the hard disk drive configuration if you install or remove
a hard disk 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 press Enter and
then F2 at the Hard disk 1 or 2 option and enter the
drive’s exact parameters.
Cl If you are using a copy-protected program that does not
require a key disk but requires a special procedure to
install it on a hard disk, set the speed to low while you
install the program. Then set the speed to high while you
load and run the program. If this does not work, try
installing and loading the program at low speed and then
change to high speed to run it.
Ci You can change the processor speed using the SETUP
program, the ESPEED program, or keyboard commands.
See the User’s Guide and Setup Guide for more information.
Password
Make sure that you do not forget the password you set. If
you do, you must disable it by setting jumper J13 on the main
system board to position A.

the program at high speed. If you can’t load the program
at high speed, set the processor speed to automatic.
