Processor Chips

If you have the 4SX/33 system, you can install an Intel OverDrive processor (ODP486-33) or a 487SX/33 microprocessor (with built-in math coprocessor) on the main system board. Installing an OverDrive processor effectively doubles the internal clock speed of the computer’s microprocessor; future OverDrive processors may be available for the 4DX2/50 and 4DX2/66 systems.

SIMM Installation

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, fast-page mode SIMMs that
operate at an access speed of 70 ns or faster, with a capacity
of 1MB, 4MB, 16MB, or 64MB. The following table shows the possible SIMM configurations;
do not install memory in any other configuration. Make sure that both SIMMs operate at the same speed. There is 4MB of memory soldered onto the main system board.

Hard Disk Drive Types

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.

Installation/Support Tips

Power

The computer has an input voltage selection switch on the back panel to select between 115V, for USA and Canadian use, and 230V, 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 can 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

Cl It is recommended that a 16-bit, AT-type hard disk
controller be used if
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 page 7 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 or 2 option and enter the drive’s exact parameters.

and then F2 at the Hard disk 1
Q
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.
0
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.

If you are using a copy-protected program that can run only on a diskette or that requires a key disk, try to load
the program at high speed. If you can’t load the program
at high speed, set the processor speed to automatic.
