AI might be wrong:
To optimize the performance of the original Doom on DOS, you might need to make some adjustments to your AUTOEXEC.BAT and CONFIG.SYS files. These adjustments can help ensure that Doom runs smoothly and takes advantage of your system's resources. Here are some common modifications you can make:
AUTOEXEC.BAT
Set a High Memory Area (HMA):
HIMEM.SYS
DOS=HIGH
Load Drivers into Upper Memory Blocks (UMBs):
EMM386.EXE NOEMS
Set the Sound Blaster (if applicable):
SB16.SYS DMA1=1 DMA2=5 IRQ=7 MPU=3
Set the Path and Prompt:
PATH C:\DOS;C:\
PROMPT
$P$G
Run Doom:
CD C:\DOOM
DOOM -FILE DOOM.WAD
CONFIG.SYS
Set the Number of File Handles:
FILES=40
Set the Number of Buffers:
BUFFERS=20
Enable UMBs:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE NOEMS
Set Device Drivers:
DEVICE=C:\DOS\ANSI.SYS
DEVICE=C:\DOS\RAMDRIVE.SYS 2048 1024 512
DEVICE=C:\DOS\SMARTDRV.EXE
Set the Shell:
SHELL=C:\DOS\
COMMAND.COM C:\DOS /E:1024 /P
Additional Tips
Use a DOS Extender: Doom itself uses a DOS extender (typically DOOM.EXE), but you can use additional tools like CWSDPMI to ensure better compatibility and performance:
PATH C:\CWSDPMI
Run in a Safe Mode: Sometimes, running Doom in a safe mode can help avoid conflicts with other drivers:
CD C:\DOOM
DOOM -SAFEMODE
Use a DOS Emulator: If you are running on a modern system, using a DOS emulator like DOSBox can help you run Doom more reliably. Here is a basic configuration for DOSBox:
[sdl]
fullscreen=true
fulldouble=true
fullresolution=desktop
output=overlay
autoscale=true
[dosbox]
language=
machine=svga_s3
captures=capture memsize=16
[render] frameskip=0 aspect=true scaler=normal2x
[cpu] core=dynamic cputype=auto cycles=4000 cycleup=100 cycledown=100
[mixer] nosound=false rate=22050 blocksize=2048 prebuffer=20
[midi] mpg123=false timidity=false
