Epson 386/25 Personal Computer User Manual


 
Introduction
The Epson® Equity® 386/25 PLUS is a high-performance
personal computer which offers exceptional speed and
convenience in a compact design. The computer’s 25 MHz
80386 microprocessor makes all your programs run extremely
fast, even when supporting multitasking operations.
Your system includes 2MB of internal memory, a built-in ‘VGA
(video graphics array) display adapter, built-in parallel and serial
interfaces, an IBM® PS/2™ compatible mouse port, and four
standard option slots (three 16.bit and one B-bit). These
interfaces allow you to connect most of your peripheral devices
directly to the computer, so you do not have to install option
cards. You can use the option slots to install additional devices,
such as a modem or a networking card.
Your computer can support up to three internal drives: either
two diskette drives and one hard disk drive, or one diskette drive
and two hard disk drives.
The Equity 386/25 PLUS offers several other features to
enhance the speed and versatility of your computer:
Memory caching. Portions of your system memory are
copied to a high-speed cache buffer so your computer can
access programs and data very quickly.
Shadow RAM. Your system ROM (read-only memory) and
video ROM are copied into the computer’s 32-bit RAM
(random access memory) to further accelerate system
performance.
Extended and super-extended VGA modes. The built-in
VGA adapter and VGA drivers (included) provide graphics
resolutions up to 1024 x 768 in 16 colors or 640 x 480 in
256 colors on compatible VGA monitors.
