Jim Hall Posts the PD-DOS Announcement That Became FreeDOS
On June 29, 1994, a Usenet post to comp.os.msdos.apps proposing a public-domain DOS kicked off what would be renamed Free-DOS weeks later — a direct response to Microsoft's plans to fold MS-DOS into Windows 95.
On June 29, 1994, Jim Hall posted an announcement to the Usenet newsgroup comp.os.msdos.apps proposing a project called PD-DOS — a public-domain, MS-DOS-compatible operating system — the post that directly launched what would become FreeDOS.
What the post actually said
Hall wrote that he’d already circulated the idea a few months earlier and found strong support, and that he had now written up a “manifest” describing the project’s goals along with a task list of exactly what needed to be written. The post followed an earlier March 31, 1994 message on a related newsgroup asking whether anyone had considered writing a public-domain DOS — Hall took up that challenge directly.
Why this specific moment
Hall was responding to Microsoft’s publicly signaled plans to phase out standalone MS-DOS as a product, folding its functionality into the upcoming Windows 95 (which would ship the following year). For the many users and systems that specifically needed DOS itself — not a GUI shell running on top of it — that created a real gap Hall set out to fill.
The rename, weeks later
In a follow-up post on July 26, 1994, Hall announced the project had been renamed from PD-DOS to “Free-DOS”, alongside a more specific commitment: source code would be distributed under the GNU General Public License, not simply placed in the public domain as the original name implied.
Why this founding moment still defines the project
Every FreeDOS release since — from 1.0 in 2006 through 1.4 in 2025 — traces back to this specific 1994 Usenet post and the manifesto it referenced. The FreeDOS 25th anniversary celebrations in 2019 marked their anniversary from this exact date, not from any later, more polished milestone — a recognition that the founding moment was this announcement, not a subsequent release.
