Welcome to FreeDOS

  • What is FreeDOS?
    FreeDOS is a free DOS-compatible operating system that can be used to play games, run legacy software, or support embedded systems. FreeDOS is basically like the old MS-DOS, but better! For example, unlike MS-DOS, FreeDOS lets you access FAT32 file systems and use large disk support (LBA).

New FreeDOS web site

2012-06-03 10:58 We created the first FreeDOS web site in 1995, providing basic information about FreeDOS. Over the years, we've tweaked the site: rewriting old text, growing new content areas, updating the design. While the design had stabilized, the content was difficult to use; information was hard to find. Since March, I've been working on an updated FreeDOS web site design. The goal with the redesign was to improve the web experience for our visitors, to make the site easier to navigate and find things that you need. And at the same time, to provide better support for mobile browsers. The new design is a result of several usability tests, where you all played a part. Thank you for your contributions to the new web site. I think we have a great new design! Take a look around.

Here is what you can look forward to: * Power awareness for virtual machines and laptops * IRCjr fixes to improve compatibility with more servers * "How-to" style documentation for setting up SLIP and PPP with mTCP * FTPSrv requires significantly less RAM * FTPSrv can be made to exclude certain drive letters * Telnet now supports Xmodem and Ymodem uploads and downloads * More newline handling fixes for Telnet (I think I got it right this time!) * The FTP client will send files much faster now - 10 to 34% has been measured."

Yes, we know the blog is down

2012-05-21 4:35 For those of you curious about why the blog is down, it's not intentional. SourceForge is having problems with the Wordpress system, which is what feeds that page. Until SourceForge fixes it, the page will be empty. Sorry. http://www.freedos.org/jhall/

New UIDE and UIDE2

2012-05-21 3:38 Jack Ellis and Johnson Lam posted a new 20-May-2012 DRIVERS.ZIP file with updated UIDE and UIDE2 drivers. UIDE and UIDE2 now have a /N5 switch, to disable diskette caching when running with "VirtualBox" or other emulators which do NOT post a diskette "media change" (new diskette has been inserted)! With /N5, UIDE and UIDE2 ignore all diskette read/write requests and just let the BIOS handle them. Diskettes will run much slower due to no caching, but users will NOT have any situations of "seeing the OLD diskette" after a new one has been inserted!

dos2unix 6.0

2012-05-07 10:35 Erwin Waterlander released dos2unix 6.0. Most important changes: * Conversion of Windows UTF-16 files to Unix UTF-8 files. * Conversion of Unix UTF-8 files to Windows UTF-8 files with byte order mark. The new functionality to convert UTF-16 to UTF-8 is only available on Windows and Unix. For FreeDOS users there is no change compared to version 5.3.3. http://waterlan.home.xs4all.nl/dos2unix.html
