Epson equity 320sx plus Benutzerhandbuch

Your computer can access RAM (random access memory)
faster than ROM (read-only memory). The Shadow RAM

feature enables the Equity 32sx PLUS to copy the contents

of its system BIOS and/or video ROM into RAM
so it can perform certain operations faster.

The SETUP Shadow RAM option lets you choose what to

place in the shadow RAM area:

0 System

3 Video

0 System and video

0 None.

unless you have installed a memory

card or video card that provides its own shadow RAM (in

which case you can select just 

or just 

if you do not want to use the Shadow RAM function.

Shadow RAM uses 128KB of the RAM available between

640KB and 1MB in your system (384KB). If you use the

shadow RAM feature, 256KB of this memory is available
for use as extended or expanded memory. If you do not
use shadow RAM, you can use all of the 384KB of RAM as

extended memory, but only 256KB of it as expanded

memory. See “Using Expanded Memory Above 640KB” in

Chapter 4 for more information.
