Since this is a DOS newsgroup, I'm going to assume that you're
talking about -true- DOS.
If you're talking about the text-mode command line interface in
WinDoze, then all bets are off. The WinDoze CLI is not 'DOS.'
Here's how you set up your CD-ROM drivers for DOS:
1. From your CONFIG.SYS file, load the driver provided by the
CD-ROM manufacturer (or a generic equivalent). This should
be done after HIMEM.SYS and EMM386.EXE are loaded (if you're
using them).
The syntax would be:
DEVICEHIGH=C:\CDROM\TAISATAP.SYS /D:CDROM-1
The drive letter and path should be self-explanatory. Here,
"TAISATAP.SYS" is the name of the CD-ROM driver. The "/D:"
parameter is where you to give your CD-ROM drive a "name."
That "name" can be anything you want.
Then, from your AUTOEXEC.BAT file, you load the 'CD-ROM
extensions' driver. This is necessary because DOS does not
have a native interface to CD-ROM drives. The 'extensions'
driver gives DOS the capability to access the CD-ROM.
The syntax would be:
LOADHIGH C:\DOS\MSCDEX.EXE /D:CDROM-1 /L:F
The drive letter and path should be self-explanatory. Here,
"MSCDEX.EXE" is the name of the 'extensions' driver. The "/D:"
parameter should contain the same "name" you gave your CD-ROM
drive in the CONFIG.SYS file. The "/L:" parameter must specify
the drive letter you want to assign to your CD-ROM drive.
There are other, more advanced options that can be used with the
'extensions' driver, but they're generally not needed. The basic
set-up, described above, should be all that's required for most
systems. Check your DOS manual for further details.

I have no idea what you mean by this, but the answer is "No."
You simply load the sound card driver, provided by your sound card's
manufacturer, from your CONFIG.SYS file. For a SoundBlaster sound
card (as an example), the syntax will look something like this:
DEVICEHIGH=C:\SOUND\CTSB16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5
See your sound card manual for full details.
Then, from your AUTOEXEC.BAT file, you'll usually need to set a
couple of environment variables for the sound card driver to use.
They'll generally look something like this:
SET SOUND=C:\SOUND
SET BLASTER=A220 I5 D1 H5 P330 T6
See your sound card manual for full details.
All of this assumes, of course, that you have a FULL HARDWARE sound
card, such as a SoundBlaster 16 -- and not a Win-sound card.
If you have a Win-sound card, you're out of luck. Win-sound cards
are brain-dead pieces of crap that rely entirely on WinDoze to
provide their functionality.
A Win-sound card does not work under DOS, and it cannot be MADE
to work under DOS. Ever.

You might be laboring under some misperceptions here, Bill.
Misperception 1:
While DOS itself may be 16-bit, the programmer can still
access all of the 32-bit capabilities of the processor and
the hardware peripherals. It's done all the time; most
modern DOS assemblers and compilers have this ability.
There's no particular reason or advantage -- especially at
this late date -- for "taking DOS to 32-bit."
Misperception 2:
A copyright is good for 50 years initially, with options to
renew it after that. PC/M$-DOS 1.0 is only 24 years old.
Therefore, the original copyright is still in effect; it
doesn't need to be "renewed."
Anyway, each new release of DOS is copyrighted as a separate
entity. So, for example, M$-DOS 5.0 -- released in April
1991 -- has a copyright that's effective through April 2041.
Hope this helps.
