CHAPTER [17]: Why won't DOOM work correctly?
--------------------------------------------
This chapter helps you if you cannot get the game to function as it
should.
[17-1]: How can I use SMARTDRV.EXE with DOOM?
=============================================
Some people have been complaining about problems with DOOM and
SMARTDRV.EXE. DOOM is not completely compatible with SMARTDRV.EXE, but
here is how you can get it to work. Try putting the following command in
your CONFIG.SYS (This will not work in the AUTOEXEC.BAT):
DEVICE=C:\DOS\SMARTDRV.EXE DOUBLE_BUFFER
The double buffering uses memory differently than the normal
SMARTDRV.EXE commands. This command will take up 2k of conventional RAM and
cannot be loaded into high memory. This has been tested on two machines that
did not work with SMARTDRV.EXE, and this corrected the problem.
[17-2]: Why am I getting an "OUT OF MEMORY" error with DOOM?
============================================================
If you are receiving an "OUT OF MEMORY" error when attempting to run
DOOM, you might want to attempt any of the following:
(1) DOOM requires at least 4mb of RAM. Check to make sure you have
at least this amount.
(2) If you are using MS-DOS v6.xx, try holding down the LEFT SHIFT key
during bootup. This will stop all your TSRs from loading. Remember to
reinstall your mouse driver, however.
(3) If you are using MS-DOS v5.0, rename your AUTOEXEC.BAT to stop all
your TSRs from booting.
(4) If you are using MS-DOS v6.xx, try running MEMMAKER to free up more
RAM at bootup time.
(5) If you are using MS-DOS v6.xx, create a boot menu. For details
on creating a boot menu, type "HELP MENUITEM" at your MS-DOS prompt.
(5) Try running DOOM without using HIMEM and EMM386. If you are
using a different memory manager, try removing it instead.
[17-3]: Why does DOOM crash when I start it?
============================================
Your motherboard may not be compatible with the DOS extender that
DOOM uses. Try getting DOOM v1.2. If that still does not work, try running
DOOM with one of the DOS extenders in the file "altdoom1.zip". See Chapter
[6] for more information on how to get these files.
[17-4]: How can I run DOOM under OS/2?
======================================
People have been having a lot of trouble getting DOOM v1.x to work
under OS/2. Native OS/2 code is being worked on, so hang in there!
Here is a list of settings that many DOOM users have been able to use.
DOS_BACKGROUND_EXECUTION OFF
DOS_BREAK OFF
DOS_FCBS 16
DOS_FCBS_KEEP 8
DOS_FILES 20
DOS_HIGH OFF
DOS_RMSIZE 640
DOS_UMB OFF
DPMI_DOS_API AUTO
DPMI_MEMORY_LIMIT 8
DPMI_NETWORK_BUFF_SIZE 8
EMS_FRAME_LOCATION AUTO
EMS_HIGH_OS_REGION 0
EMS_LOW_OS_REGION 384
EMS_MEMORY_LIMIT 2048
HW_NOSOUND OFF
HW_ROM_TO_RAM ON
HW_TIMER ON
IDLE_SECONDS 0
IDLE_SENSITIVITY 100
INT_DURING_IO ON
VIDEO_TRETRACE_EMULATION OFF
VIDEO_ROM_EMULATION ON
VIDEO_SWITCH_NOTIFICATION OFF

XMS_MEMORY_LIMIT 2048
XMS_MINIMUM_HMA 0

CHAPTER [18]: Why won't my sound card work with DOOM?
-----------------------------------------------------
This chapter helps fix problems with various sound cards in DOOM.
[18-1]: Why won't my Sound Blaster v1.0 or v1.5 work with DOOM?
===============================================================
The v1.0 shareware release of DOOM does not work correctly with
earlier versions of the Sound Blaster. It is recommended that you receive
v1.2 of DOOM to fix this problem. Information on getting this upgrade is
available in Chapter [6].
If you insist on using v1.0 of DOOM, here are two different ways to
fix your problem, although they are not guaranteed to work on all computers.
(1) If you have a turbo button on your computer, turn it off. Run
DOOM, and when the title screen appears, turn it back on.
(2) Disable the internal cache.
[18-2]: Why won't my Sound Blaster Pro work with DOOM?
======================================================
If you are using an older graphics card that supports HiColor (16
bit graphics) you may have trouble getting this to work correctly. The
only recommendation is to borrow a friend's graphics card.
DOOM v1.1 has a bug that keeps the Sound Blaster Pro from working
on IRQ 2, and later versions do not allow usage on IRQ 10.
[18-3]: Why won't my Gravis UltraSound work with DOOM?
======================================================
To get DOOM to run properly with both music and digitized sound
effects on the Gravis UltraSound use these three steps.
////// SOUND //////
(1) Set your ULTRASND environment variable, and use GF1 IRQ less than 8
example: SET ULTRASND=220,1,1,7,5
|_______ GF1 IRQ
NOTE: DOOM v1.2 may be able to use any valid GF1 IRQ including 11,12,15
However, high IRQs are _not_ recommended. See BUGS.
////// MUSIC //////
(2) Doom requires that you have installed the General MIDI patch set from
the 2.06a Install Disks (or later) that came with your UltraSound (and are
also available via FTP and BBS). DOOM will find your patches (using the
ULTRADIR variable) in the MIDI subdirectory pointed to by ULTRADIR.
example: SET ULTRADIR=C:\ULTRASND
(DOOM will look in C:\ULTRASND\MIDI for the patches)
NOTE: Step 3 is only required for DOOM v1.0 / Operating System 0.99
(3) You will also need to copy ULTRAMID.INI into your DOOM directory and
rename it to DMXGUS.INI (or find and use the DMXGUS.INI file). ULTRAMID.INI
is a part of the UltraMID/AIL package (also available via FTP and BBS).
////// SETUP //////
Run the SETUP program in the DOOM directory and select the UltraSound for
both sfx and music. Now run DOOM!
////// BUGS //////
NOTE: DOOM v1.2 is known to occasionally lockup with GUS support.
If you experience frequent lockups AND are using a high GF1 IRQ
(10,11,12,15), try using a low IRQ (less than 8).
If you experience frequent lockups AND have less than 1024K of
GUS RAM, try upgrading to 1024K (1 Megabyte).
////// OPTIMIZING //////

Title : GUS1M.WAD
Author : Tom Klok
Email Address : a344@mindlink.bc.ca, a00344@giant.rsoft.bc.ca
Description : An optimized MIDI instrument mapping for
Gravis Ultrasound cards with 1024K on board.
NOTE! If you don't have a GUS with 1024K, this wad will gain you
nothing (but shouldn't hurt anything either).
This PWAD contains no new MUS music files or sounds whatsoever.
Nor does it require any new .PAT files, just those supplied
with the more recent install disks.
========================================================================
Information
~~~~~~~~~~~
As you probably know, Doom's wad file contains a resource named
DMXGUS which contains a list of all MIDI instruments (patch file
names) and a table specifying which instruments to load into card
memory. Since all 190+ instruments can't be loaded at once, the DMXGUS
file loads a subset of the full GM set and then maps the remaining
instrument numbers to the loaded instruments.
I was curious about the internal format of MUS files, and pretty
happy when the MIDI2MUS utility was released. Thanks, guys! Mu
