1: Introduction
Overview
This manual covers the information you need to service or upgrade the L295N/L297N LCD computer. Information about
operating the computer (e.g. getting started, and the Setup utility) is in the User’s Manual. Information about drivers (e.g.
VGA & audio) is also found in User’s Manual. That manual is shipped with the computer.
Operating systems (e.g. DOS, Windows 9x, Windows NT 4.0, Windows 2000, Windows XP, OS/2 Warp, UNIX, etc.) have
their own manuals as do application software (e.g. word processing and database programs). If you have questions about
those programs, you should consult those manuals.
The L295N/L297N LCD computer is designed to be upgradeable. See “Disassembly” on page 2 - 1 for a detailed de-
scription of the upgrade procedures for each specific component. Please note the warning and safety information indi-
cated by the “” symbol.
The balance of this chapter reviews the computer’s technical specifications and features.
