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.
