Hi anonymous Abwesend forum member who is pessimistic about DOS ;-)

FreeDOS no, old DOS games yes.

> FreeDOS on the other hand is a very old operating system concept.

Old concept yes, old operating system no. This means: DOS
has no multi tasking and no 64 bit address space, so your
modern computer will be bored: Only a single CPU core and
at most 3 to 4 GB of RAM can be used inside DOS. Which is
of course a lot more than old DOS games ever could imagine.

This leads to the next problem:

Old DOS games do not use "DOS drivers" for sound. They could
not imagine that games would have any more fancy sound card
available than a stereo SoundBlaster. So the games THEMSELVES
contain drivers for SoundBlaster. DOS kernel is unable to tell
a game that it must use your computer has 7.1 channel surround.
This is where DOSBOX and similar special tools comes into play:

DOSBOX can show your game a SIMULATION of a SoundBlaster card
and capture all sound from that simulation. It can then send
the sound to your REAL sound card so you can hear the sound
from the front speakers of your surround system :-)

Note that you CAN run a modern media player for DOS, which is
aware of surround sound cards, to enjoy MP3 & OGG on modern PC.

Is there anything else than sound which has problems in DOS on
modern hardware, when playing old games written in the 1990s?

Note that DOS also does not involve networking in the operating
system itself: You may have a DOS web browser which supports a
common packet driver interface. The DOS kernel does not care if
you have packet drivers or web browsers. So because you will not
find a packet driver for your wireless network, the DOS kernel
can not help your DOS web browser to use a wireless network.

Which other "dozens" of drivers do you miss? Interesting topic!

Cheers, Eric
