I did try to install and use freedos several years ago.  It wasn't 
possible to use freedos though I did manage to get it installed.  The 
reason was probably the screen writes for the operating system were going 
too fast for my screen readers to capture them and speak them.  I tried it 
with both jaws for dos and provox 7 which was the last version of provox 
released and provox is the only open source dos screen reader now too. 
Unfortunately it's no longer supported either.  Mostly C but some a86 
assembly language was used to write it.  I didn't try freedos with 
tinytalk though but don't think tinytalk could have done any better with 
it.  So my questions are first has any accessibility work ever been done 
on freedos with a goal of making freedos useable by populations with 
sensory disabilities?  If so, does any command or switch or configuration 
option exist to slow the screen writes down to the speed drdos does them 
when newui=off is set?  If that does, it might be worthwhile me trying 
another installation attempt and screen reader tests.  One of the 
computers I have only runs dos and gets out on a dial up modem and is now 
running drdos.  It's got an ethernet card but apparently this card gets 
set up in the cmos and drdos can't find it.  Most of the drivers available 
for ethernet for drdos are isa and this is also a pci card.  I don't know 
that freedos will ever be able to do any better but would be willing to 
find out.
