  INSTALLATION ON THE DOS PLATFORM WITH DJGPP
  -------------------------------------------
 
- Openssl has been ported to DOS, but only with long filename support. If
- you wish to compile on native DOS with 8+3 filenames, you will have to
- tweak the installation yourself, including renaming files with illegal
- or duplicate names.
+ OpenSSL has been ported to DJGPP, a Unix look-alike 32-bit run-time
+ environment for 16-bit DOS, but only with long filename support.
+ If you wish to compile on native DOS with 8+3 filenames, you will
+ have to tweak the installation yourself, including renaming files
+ with illegal or duplicate names.
 
  You should have a full DJGPP environment installed, including the
  latest versions of DJGPP, GCC, BINUTILS, BASH, etc. This package
  requires that PERL and BC also be installed.
 
- All of these can be obtained from the usual DJGPP mirror sites, such
- as "ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp". You also need to
- have the WATT-32 networking package installed before you try to compile
- openssl. This can be obtained from "http://www.bgnett.no/~giva/".
+ All of these can be obtained from the usual DJGPP mirror sites or
+ directly at "http://www.delorie.com/pub/djgpp". For help on which
+ files to download, see the DJGPP "ZIP PICKER" page at
+ "http://www.delorie.com/djgpp/zip-picker.html". You also need to have
+ the WATT-32 networking package installed before you try to compile
+ OpenSSL. This can be obtained from "http://www.bgnett.no/~giva/".
  The Makefile assumes that the WATT-32 code is in the directory
  specified by the environment variable WATT_ROOT. If you have watt-32
  in directory "watt32" under your main DJGPP directory, specify
  WATT_ROOT="/dev/env/DJDIR/watt32".
 
- To compile openssl, start your BASH shell. Then configure for DOS by
- running "./Configure" with appropriate arguments. The basic syntax for
- DOS is:
- ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
+ To compile OpenSSL, start your BASH shell, then configure for DJGPP by
+ running "./Configure" with appropriate arguments:
+
+       ./Configure no-threads --prefix=/dev/env/DJDIR DJGPP
  
- You may run out of DPMI selectors when running in a DOS box under
- Windows. If so, just close the BASH shell, go back to Windows, and
- restart BASH. Then run "make" again.
+ And finally fire up "make". You may run out of DPMI selectors when

+
+ Quoting FAQ:
+
+  "Cryptographic software needs a source of unpredictable data to work
+   correctly.  Many open source operating systems provide a "randomness
+   device" (/dev/urandom or /dev/random) that serves this purpose."
 
- Building openssl under DJGPP has been tested with DJGPP 2.03,
- GCC 2.952, GCC 2.953, perl 5.005_02 and perl 5.006_01.
+ As of version 0.9.7f DJGPP port checks upon /dev/urandom$ for a 3rd
+ party "randomness" DOS driver. One such driver, NOISE.SYS, can be
+ obtained from "http://www.rahul.net/dkaufman/index.html".
