DR DOS 8.x

DR DOS is an MS-DOS compatible operating system from Digital Research that evolved from their earlier CP/M-86 based products Concurrent DOS and DOS Plus.

Release notes

In 2002 Lineo was bought out. Former employees created Devcelogics LLC that continued to sell DR-DOS for use in embedded systems. In 2004 Devicelogivs released DR-DOS 8.0.

DR DOS, Inc. was then created as a spin-off and released DR-DOS 8.1.

While DR-DOS 8.0 was based on DR-DOS Kernel 7.03.[46], 8.1 is instead based on OpenDOS/Enhanced DR-DOS 7.01.xx.

Shortly after release, it was discovered 8.1 as well as 8.0 contained works from FreeDOS, none of which were credited and source was not provided. When the FreeDOS project pointed out this was a GPL violation, DR-DOS, Inc pulled both 8.1 and 8.0 from the market.

Note: It appears 8.1 was distributed as a file set. To install, create a boot disk using "Bootdisk.img" and manually copy all files to a DOS folder.
