Try running something more primitive just to make sure that something IS working in DOS. When you say you can't run anything in DOS, you mean not even dos's editor for example?

Yes sorry,

I can run things like EDIT and quite a few setup programs, such as setsound for various games. It's just when I try to load games.

Sam & Max Hit the Road - Works perfectly in Windows with sound, stops responding when I type sam.exe in DOS
Nascar Racing - Not a Window Games, I type Nascar at command prompt, from Bootable floppy or F8, Command Prompt and it stops with the cursor flashing
Screamer 2 - Works perfectly in Windows, reboot to DOS, can load setup which has a GUI but stops responding again when I type in screamer with the cursor flashing
Quake - Works perfectly in Windows, reboot to dos, goes to load then errors (Need to find the error, its quite long)

Thanks,
Mark

Probably some hardware conflict with PNP hardware that is resolved in Windows, but not in DOS.

Pull everything out that is not needed, set everything to default settings in BIOS. Also remember that alot of games will crash in DOS if you have sound parameters entered and no sound card/drivers loaded.

What vetz said.
Some hardware issue you are having is negated in a dos box on Windows.

- Try stripping it down to a minimalistic DOS config, reducing (removing / replacing) RAM if you can - I know 32 Mb is practically the smallest and for some games even that is too much, but you can use eatxms or several RAMdisk drivers to reduce available RAM for DOS.

- not for late DOS4GW games like Screamer 2, but for earlier ones: use speed throttling utilities (SetMul by gerwin can at least enable/disable caches for your processor. If you upgrade to a K6-II+ or III+ then it can also lower the multiplier)

start with a standard, unoptimized autoexec.bat like below (adjust paths where necessary)

1@ECHO OFF
2PROMPT $p$g
3SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;
4SET DIRCMD=/P /A
5SET TEMP=C:\WINDOWS\TEMP
6SET TMP=C:\WINDOWS\TEMP
7SET BLASTER=A220 I5 D1 H5 P330 E620 T6
8SET SOUND=C:\PROGRA~1\CREATIVE\CTSND
9SET MIDI=SYNTH:1 MAP:E MODE:0

11rem        C:\WINDOWS\COMMAND\MODE CON RATE=32 DELAY=2
12rem        LH /L:2 C:\WINDOWS\COMMAND\DOSKEY /INSERT
13rem        missing lines for the AWE64  to work in DOS.  Adjust  the paths to your directories !
14SET CTCM=C:\CTCM

and config.sys:

1DEVICE=C:\WINDOWS\HIMEM.SYS /V /testmem:off
2DEVICE=C:\WINDOWS\EMM386.EXE 4096 RAM
3DOS=HIGH,UMB
4FILESHIGH=40
5BUFFERSHIGH=40
6SHELL=C:\WINDOWS\COMMAND.COM C:\WINDOWS\ /E:1024 /P

Just been playing around with this tonight and took out the Voodoo 3 2000 and Doom which previously crashed booted up instantly. I can now run Nascar & Screamer...

Edit - Now just started doing it with the o/b graphics card. I've yet to have sound in DOS. Might try a new install.
