- This file specifies the requirements of this demonstration
- and gives tips for running it. It might be a good idea
- to read this file throughly, especially if you encounter
- problems...
-
- Unreal requires:
- - 2.5MB of disk space (you probably already know this :-)
- - a 386 or a 486 computer (preferably the latter)
- - 600K (actually 600000 bytes) of memory. You *CAN* use a
- 386 memory manager like QEMM to get this memory available.
- - also a SoundBlaster, SoundBlaster Pro, or Soundmaster II
- soundcard will make the demo more fun to watch, although
- the demo is able run without sound.
-
- As you can probably understand, the sheer size of the Unreal
- makes it impossible for us to make sure it works in every
- possible configuration given the time we have had to produce it.
-
- However, we have tested it as throughly as possible. And there
- are a few points that will probably solve the possible problems
- you might have running this demo.
-
- First of all, you might simple try running the demo with
- your normal configuration, and if it works ok, clearly no
- problem exists. However, if the demo hangs or runs VERY
- slowly or you don't have enough memory, try the following:
-
- To get memory, try installing a 386 memory manager (such
- as QEMM 386 or 386MAX) and/or removing all unnecessary
- residents from config.sys and autoexec.bat. Also decreasing
- the value of the buffers statement in the config.sys will
- help a little.
-
- If the demo doesn't work properly but you do have enough
- memory, first try removing all disk caches and other active
- residents (programs that do something and don't just eat
- your memory until you call them up with a hotkey). Things
- like enhanced keyboard drivers that intercept things like
- video and keyboard interrupts may cause problems because
- the Unreal clearly isn't your average dos application using
- machine resources as usual.
-
- If this doesn't help, try running without sound. Especially
- in slow machines, the sound output can interfere with the
- hard disk transfers and this will most surely cause a hang
- when the demo loads more data from the hard disk between
- parts. Also, disabling sound in slow machines is the best
- way to get the demo run faster. Some of the tunes use up
- to 10 digitized channels, and with 20Khz playing speed in
- a slow 386SX this takes up nearly half of the frame time!
-
- As a last option, try creating a boot disk etc. and load
- ONLY the NECESSARY drivers to memory. That is, possibly a
- hard disk driver (for SCSI etc.) and QEMM if you can't get
- enough memory otherwise. Leave all extras out like your
- countrys keyboard driver, mouse driver and so on. If this
- doesn't help either, your machine might unfortunately be
- too unique for the Unreal to work completely.
-
- If the demo always hangs in the same place, you might try
- skipping the problem part by pressing ESC immediately when it
- starts. Also, if the part hangs before you have a chance to
- hit the key, you can, as the final solution, run the demo part
- by part. This is accomplished with the following command line:
- UNREAL P#
- where # stands for the part group number (1..9). First you run
- UNREAL P1, then UNREAL P2 etc. and just leave the part group
- out that is causing problems. This, of course is a bit harder,
- but at least you will see the rest of the demo.
-
- Well, after reading this file you probably think that Unreal is
- full of bugs and the most incompatible program ever created...
- You are probably right :-) The Unreal has been created in a
- pretty short time (a month or so, except for some older parts
- which are nearly a year old). It contains so different routines,
- many utilizing some undocument (yet theoretically IBM VGA
- compatible) effects that even small incompatibilities or
- differences may trigger problems. There is also a lot of source
- code for the bugs to hide in (about 40000 lines not counting
- include files like sin tables) so hunting them down is not a
- trivial task. Also, as you will find out, Unreal takes up quite
- a lot of processing resources... Our goal was to make a great
- demo at the cost of bigger processor requirements... Keep this
- in mind while watching this presentation!
-
- In any case, we believe that Unreal as an experience is worth
- the trouble getting it working :-) We hope you will also think
- so after enjoying it.
