# System Requirements

This document lists the system requirements for running Eagle Mode. Please read carefully.

CPU: | 2 GHz, 1 MB cache.
Memory: | 1 GB RAM and 1 GB swap space (or more RAM). This is a recommendation. If you run Eagle Mode with less memory, then your first job after starting should be to navigate to the Preferences (somewhere in the upper left area of the control view) and lessen the value for Max Megabytes Per View.
Disk: | About 15 MB disk space for installation, 1 GB for temporary files at run-time. The disk should be quite fast and without frequent sleep states (notebook hard disks are not so suitable).
Operating system: | An up-to-date Linux is recommended. Other UNIX-like systems may also be suitable (tested were FreeBSD, OpenSolaris, Cygwin and Mac OS X 10.5). Eagle Mode also runs on Windows ≥ 2000-SP2, but several features are not ported (UTF-8 encoding, time zones, audio/video player, postscript viewer, viewers that perform temporary conversion).
Graphics: | An accelerated graphics driver. On UNIX-like systems it should be an accelerated X-Server with a fast XShm extension. 3D acceleration is not needed. It is not recommended to use something like a 3D desktop or composite manager, because that could slow down Eagle Mode a lot.
Mouse: | With three buttons (not emulated) and with a smooth-running wheel.

Programs & Libraries:
Program/Lib | Debian Package Name | Required?
perl (Perl >=5.8) | perl | By all means (but on Windows only for compilation)

Do not have the wrong program to a name

Eagle Mode runs many standard programs by names like they have on Debian GNU/Linux 5.0. Your system must not have another program with one of those names, otherwise unforeseeable things could happen. For example, Eagle Mode runs "gs" when it means Ghostscript, and therefore you should not have another program named "gs" which, for example, formats the hard disk. In detail, Eagle Mode runs standard UNIX shell commands like "cp", "mv", "rm", "grep" and so on, and it runs the programs listed in the table above. Many of these are run when you just navigate around in Eagle Mode, without asking you. In addition, many further programs (not listed above) are run by triggering the file manager commands. If you are unsure about the later, please study the file manager command scripts (see emFileMan Customization for a description of the scripts).
