My school has recently updated the computers found in the Computer Science lab. We used to have old computers with Windows 98, but they were replaced exactly one week ago with semi-new Pentium 4 IBM machines with XP Professional. On the old machines, we would use headphones to make the annoying sounds possible in DOS (as made by C++) less audible to anyone except the programmer, thence making it less annoying. However, upon upgrading them we foud that the sounds are no longer sent through the headphones, and are instead sent through the computer itself. This can get extremely irritating with 30 students all playing extremely annoying high-pitched noises. This problem only happens with DOS, though; when out of DOS on the normal Windows desktop, the sounds go through the headphones as normal. Does anybody know of any way to fix this incredibly annoying problem?

I WILL SAY AGAIN THERE IS NO MSDOS IN XP IT IS AN EMULATION I WILL SAY AGAIN THERE IS NO MSDOS IN XP IT IS AN EMULATION please read this article and stop reciting MSdos in xp, it is command prompt / cmd.exe http://www.windowsitlibrary.com/Content/226/03/1.html

Think about dual booting Windows 98 and Windows XP as a possible solution.You setup Win 98 first on a small C primary partition set active of about 4 GB.You partition the balance extended partition as logical partitions(one or more).You setup the Windows XP on D drive.The XP setup program will install the boot loader and make it possible to work your lab experiments with sounds like you did before.Partitions made with Windows 98 dos boot disk should not exceed 32 GB to avoid error reporting. You can also try to run the experiment in a dos box.This would be a lot simpler than convincing the school board about dual booting advantages!Good luck.
