| Okay, when booting in DOS itself, there are 3 files that start; io.sys,
msdos.sys, and command.com. These 3 files are needed to run DOS, correct?
What about config.sys and autoexec.bat?
When booting WIN9x/ME, im loading the same 3 files right, but these are then
not needed once windows actually loads its drivers, correct?
Thanks in advance...

| config and autoexec are not REQUIRED to run dos!! If you have dos programs
that need a mouse, sound, etc then autoexec.bat is needed to load these
drivers! If I remember correct it would be needed to use expanded/extended
memory as well!

What you get's a prompt for date and time and then your C:\ prompt is
actually more like c> and won't display the current directory. The memory
managers aren't loaded so all you have's the 640kb of conventional memory
unless you're using a very old program designed to address memory directly.
You'll have no drivers loaded, so the cd-rom, sound card, mouse, etc. won't
be operative unless again, you're using software that addresses the
hardware.
Programmers today rely on their API's so they don't have to concern
themselves with the hardware and memory management.

Autoexec.bat and config.sys are not required to boot a PC. They are
required by other programs or drivers running under DOS, or other
environment changes, but not required just to boot a PC.
