IT doesn't use dos that I know of. I used to work in IT. I think you will find
out that freedos is for
- embedded systems developers
- people who want to run their old DOS programs.
- probably some other uses I am not covering, like POS
I do research like anybody else. but I am not skilled in writing an OS (but I
am trying to learn about coding multithreading, who knows, maybe I can do it on
top of DOS! touch subject with too much to read that's over my head right now,
dig into the intel manuals if you don't believe me.).
If you don't like the internet, why are you on it? I use it for a research
tool. it's because I can't get out to the library, and the library has almost
no technical books. I also have an easier time asking for permission to use
something, again, because I can't get out. on the internet, sometimes you get
good stuff, and sometimes you get junk or in between, or things I didn't think
about, or stuff that's not standardized (like most javascript functions).
sure, I have a library of my own.
my only trouble in making a multithreading API on top of DOS is that there's no
compiler for it. gcc runtime and some libraries must be custom built for that
kind of platform.
I really need multithreading in DOS to parallelize some disk wipe or refresh
jobs to take FAR less time. I like efficiency. and dd is very very slow for
some reason.
I like coding for DOS, it's easier. linux isn't an easily customizable system
like DOS, it requires linux to build linux and there are very few
cdrom-building packages out for it and they are hard to use. DOS you just
compile a program and run it and you are done and it's cdrom-able. only thing
you need is freedos ripcord and a boot sector image and the proper files and
you are good to go with bootable [disk] utilities. I think such a disk utility
could possibly also work with GPT from a structure point of view without having
to mess with UEFI calls, but I am thinking that the partition GUIDs MAY need to
be regenerated (more research?) if the disk is repartitioned or partitions
moved, or . but maybe not.
in windows something changes (dialog boxes fly by) there when I switch a drive
form one channel to another with GPT. so I am thinking that ther eis something
more under the hood.
I still think it would be nice to have tuxera ntfs-3d filesystem support in
freedos with LFN. but then would it b DOS? also, NTFS is "not meant for
removable drives". this is why we have exFAT, fat32, etc.
would love to see exFAT/FAT64 support in freedos, or dos-like OS. I don't care
what the OS is, as long as it:
- has a compiler for it I can hopefully run on windows
- it's easy to set up and cdrom
- has the needed utilities
- I can just hit the reset button when I need to without consequence, like DOS
- has long filenames
- multithreading support both in the compiler and in the OS
- either multitasking or task switching.
- no improper limitations on the fliesystem size that aren't in the filesystem
spec
- uses a commonly used filesystem (there is a free paragon ext2/3/4 for windows
by the way)
- filesystem works with windows I hope (NTFS, FAT32, FAT12 (floppies),
- floppy drive support
- cdrom support
- network support optional
- a command shell prompt with decent scripting capabilities
- text screen is fine for most of what I do, but should have some sort of
access to graphics
exFAT is 64-bit and is licensed I am pretty sure. on my cdroms and installation
of DJGPP I really need to get around that 8.3 filename thing.
not sure, but I *think* reactos.org is supposed to be an XP clone might be just
that. it's cdromable (you can make a livecd) and right now it's only fat32.
compilers are definitely available and it has all the above except for
filesystem limitations probably.
*****
if ANYONE has learned what switches to use to get DOSLFN to work with freedos,
PLEASE post to this mailling list! thanks, much appreciated. I have tried
everything I could and failed, out of ideas, and testing all possible
configurations would take FAR too long due to the sheer number of
options/switches.
tried posting before but got no answer. help would be greatly appreciated if
someone has the answer.
thanks.
