SvarDOS – an open-source DOS distribution

So apparently this isn't "just" a FreeDOS distro? That's interesting; I sorta didn't realize there were multiple living DOS implementations.

The idea is to make it more compatible with DOS 6.x

So I believe things like Long filenames are not emphasised.

DR DOS was Digital Research's MS-DOS clone. For a while it had more features and ran better than MS-DOS. In the mid-90s, Caldera bought the rights to DR DOS so they could bundle it with their OpenLinux Linux distribution. They briefly released its source code (renamed to "OpenDOS"), but not as an open source license. The license only allowed free use for educational and evaluation purposes. You were required to buy a license from Caldera after 90 days for commercial entities or after a "reasonable period" for non-commercial entities. They then closed the source code again after a few months. The Enhanced DR-DOS project is based off this code release. They seem to have replaced the license in the repo with an email log that releases the code to CP/M as open source, but doesn't mention DR DOS at all. This is a bit sketchy but DR DOS has no commercial value so I doubt anyone will mind.

The biggest impact Caldera's purchase of DR DOS had was that they were able to sue Microsoft for not making Windows 95 compatible with other DOS's besides Microsoft's. Caldera were able to demonstrate Windows 95 booting on DR-DOS with the assistance of a small TSR, which helped the lawsuit (see https://msfn.org/board/topic/109018-windows-98-in-dr-dos/ ). This functionality was never released publicly. Microsoft ended up settling out of court and paying Caldera $280 million.

btw, if you want to keep up with the freedos community (unfortunately) the facebook group is the best place to do it https://www.facebook.com/groups/freedosproject/

I refuse to create a facebook account. There are alternatives[0].

Great for svardos users, not ideal for the rest of the FreeDOS community, however.

As an aside... I wonder how many people use VPNs among the HN crowd. I've been on a VPN so long, I feel really exposed when I'm forced to access anything without one.

Is this link really http? Safari on latest iOS refuses to open it.

(All modern browsers will do the same although on desktop you could bypass security restrictions.)

On the upside not being able to open the link led me to find out 86box emulator.

That's interesting, Firefox and Safari on iOS 18 do open it - didn't know that they changed the default behaviour in 26 apparently.

But yes it's HTTP-only, I think it's by choice.

It’s working now, must have been something to do with ISP/Firewall/?. Thanks

To work with Arachne?

Old school :)

Maybe the comments form in the forum could use https. Nothing else that I can see really needs it.

In addition to the httpd on port 80, there is also a gopher server

   echo /ogup/list|nc -vvn 51.210.178.223 70

Copies of DR-DOS:

   echo /abandonware/os/DR-DOS|nc -vvn 51.210.178.223 70

bladeenc... now that brings some memories!

svardos comes with a nice package assortment indeed
