VGA and IDE Drivers
Your computer comes with special VGA and IDE drivers for
use with the integrated local bus VGA interface and the local
bus IDE hard disk interface. With the VGA drivers, you can
take advantage of the extended VGA features such as high
resolutions and 132-column text mode when you run popular
application programs. With the IDE drivers, you can take
advantage of the high-speed, 32-bit local bus IDE hard disk
drive interface. Instructions in Chapter 6 describe how to install
the VGA drivers for Microsoft ® Windows ® 3.1 and how to
install the IDE drivers. Other VGA drivers are available from
the Epson Electronic Bulletin Board or from our worldwide
network of subsidiaries and distributors. To access the bulletin
board, call (310) 782-4531.
Optional Equipment
You can easily upgrade your computer by installing additional
memory and a wide variety of options, as describe d below.
(Installation instructions are provided in Chapters 4 and 5.)
System Memory
By adding 1MB, 2MB, 4MB, 8MB, 16MB, and 32MB SIMMs
(single inline memory modules) to the main system board, you
can expand the computer’s memory up to 64MB.
Cache Memory
You can increase the cache memory on your main system board
to 64KB, 128KB, or 256KB by having additional SRAM chips
installed by an Authorized Epson Servicer. Additional cache
allows your system to access frequently used data faster.
