That sounds like a pretty convoluted and backwards solution. DOSBox is an emulator. If you have real hardware, that you don't need to emulate, why do you need DOSBox? It looks like you are essentially trying to use DOSBox as some sort of slowdown utility. There are far simpler and effective solutions for this problem.

DOSBOX is at this state by far the better option then ANY slowdown-utility. Most of them do not work properly on a PII/Celeron,
some cause serious problems, some do not prevent the software from crashing. The only Problem is, that I picked a slightly
underpowered CPU.

I expected Doxbox to use the real hardware if the machine has it and it's properly configurated.

No, DOSBox is an emulator. It emulates the hardware, so having the real one is no benefit (there is an outdated patch to pass through ISA soundcards on Linux, I think).
AND emulation needs raw CPU power, for 90ies and especially mid-90ies you need much more power than you have.

Technically that shouldn't be possible.
DOSBox is a Windows application, and Windows prevents direct access to the hardware. Some hardware is protected altogether, other hardware is programmed specifically by Windows, and reprogramming it will crash the system. In Win9x, some of the hardware was virtualized, so DOS applications running in Win9x 'thought' they could access it, and it may or may not work. Eg, you weren't allowed to reprogram the timer interrupt, because Windows uses it for its task scheduler.
This breaks most games/demos, which want to use the timer interrupt to sync things to the screen refresh and such.

Likewise, Windows is a multitasking OS, so it has to share its hardware between processes. You can't have a single process access your sound card directly, because Windows is in charge of the sound card, and it uses a mixer to make multiple processes use the same card at the same time. Or in the case of a midi synth, you can only send midi data to Windows at a high level, and Windows decides how and when it is sent to the card. You are not allowed to directly access the hardware like in DOS.

Thx! The newer games that use dosextenders run good on that machine (duke, blood, etc.)
Because the slowdown-utilities for dos with a PII/Celeron do not work so good, I thought
about using Dosbox, but you made it clear, that this a dead end, especially on that machine.

So I should try some Windows-Slowdown Utilities, they should effect the dostitles started
under Win9x also.

DOSBox is not Windows application, it's open sourced and may to have ports to other OS with less limitations. It may be run with DOS extender. Windows itself may to have patches/drivers/software to extend limits. Some additional hardware may be used. DOSBox has kind of passthrough patch for FM, but I doubt it makes things much faster. There may exist ways to make passthrough mode for sound cards. But as not many ones need this, it's more reasonable to use 2nd faster machine for DOSBox.
As for your CPU, you may speed it up a little by overclocking. Or try other close CPU like Celeron 300A many of wich could be overclocked to 450-500 MHz (100/110*4,5) what will give ~2 times more speed in DOSBox. Result should be slow for 1993-... stuff, anyway, but at least something.

Thx, I did not update the signature yet. I currently use a Celeron 400 and trying to get it in 433 Mhz (SL3BC)

Many 300A allow 100-112 FSB, besides higher frequency up to 450-504 MHz. If you seek for maximum with Intel, while keeping low speed close to P2 333.

My board has max FSB66, so no 100/133 FSB

If you are interested in Win9x games too, 66-133 FSB board like Asus P3B-F 1.04 is better choice.

Yes I know, but the machine itself is safe, so no other board.
