PRIMEEMX.EXE

This is a DOS port of the Mersenne prime program by George Woltman for
Linux. Although it is possible to run this version on OS/2 I strongly
advice you not to do for two reasons: 
1. This version runs 1.5% slower using OS/2 than PRIMEOS2
   OS/2 users are adviced to use PRIMEOS2.EXE instead of PRIMEEMX.EXE.
2. PRIMEEMX has no PRIMENET facilities. 

See the readme.txt and whatsnew.txt files as written for the Linux
version for more information.

Version 3.3.1 contains the functionality of the 18.1.2 version of
George's program mprime for Linux. 

NOTE for those upgrading from a previos version.
The menu items have changed numbers because of the new Testing/ECM

SYSTEM REQUIREMENTS
===================

You need the EMX runtime system that can be obtained from:

	ftp://hobbes.nmsu.edu/os2/dev/emx/v0.9c/

it has the name emxrt.zip. (The version (v0.9c) might change in the
future).

If you want to run PRIMEEMX in a Windows 3 environment (actually W95
and NT too, but I can't imagine why you should not use PRIME95 then)
get the RSX package instead of EMXRT at:

        ftp://ftp.uni-bielefeld.de/pub/systems/msdos/misc

EMX and RSX need at least 1 Megabyte of memory. Because of the great
amount of memory needed I would not advice to use the program on a
system with less than 4 Megabytes (for small exponents up to 16 for
the real big exponents) available.

Please read for more detailed information the documentation provided
with emxrt.zip.
