Microprocessor Upgrades

Hard Disk Drive Types

The computer’s processor can be upgraded by replacing the

existing microprocessor with a faster one. You can either

purchase an upgrade kit from Epson or buy the individual

components separately, as listed in the following table.

Microprocessor upgrade components

*For the SX/25, SX/33, and DX/33 processors

**For the DX/50, DX2/50, DX2/66, and Pentium OverDrive processor

SX/25, SX/33, and DX/33 processors require a heat sink.

DX/50, DX2/50, DX2/66, and Pentium OverDrive

processors require a heat sink and a fan. Make sure jumpers

J16, J17, and J19 are set correctly for the new processor.

Fan Installation

Some upgrade kits for processors that require both a heat

sink and a fan contain a separate fan assembly. Secure the fan

to the bracket using the long screws and the nuts. Then

secure the bracket to the chassis with the short screws.

Connect the fan connector to J12, aligning the small triangle

on the case of the connector with pin 1.

This system comes with a hard disk auto-sensing feature.

When 

you press 

Enter with 

the cursor positioned on the

Autotype Fixed Disk 

option in SETUP, the system

detects the type of hard disk drive you have installed and fills

in the drive information using values in the following table.
