Re: [Freedos-user] Run Linux & Linux binaries on DOS

In the mid 1990s I copied the Tru64 shared libraries and some other things from one of the universities Tru64 machines onto an Alpha running Linux in my office. With a very small amount of hacking around and configuring I got Mozilla and maybe a few other things to run. Other than showing ever

I remember, from DR-DOS website (drdos.com to the best of my memory), in their later years DR-DOS could load Linux and come back to DR-DOS after the user exited from Linux. As far as I could see, it was not possible to run DOS and Linux software concurrently. I never tried that, believe DR-DOS

After poking around the GitHub project, this is actually a very clever thing. Looks like he's using VM86 mode (requires '386 or later CPU) to instantiate a dedicated Linux kernel with BusyBox to run the Linux commands. This is not bringing up a full Linux installation in a VM - this is only the ker

The author freely admits running DOS & Linux side-by-side this way is a fragile coordination [0]. I doubt that redirection would work as one might desire. The recently updated ascii demo [1] shows calling various DOS and Linux commands, and, shows creating a text file with `dsl vi hello.txt` and

Hi everybody, I would predict doslinux to be a variant of a Linux loader, so my questions here are: Can Linux safely write to the DOS partition while running? What are the limitations to return to DOS after using Linux? Is it possible to switch between DOS and Linux without having to reboot Linu
