86-DOS 0.3

86-DOS 0.3 was the fourth release of QDOS/86-DOS. It was the first release licensed to Microsoft.

On 7 July 2021, the BIOS and boot sector was uploaded to the BetaWiki Discord server by Lucas Brooks. The boot sector was the same as the ones found in 86-DOS 1.00 and 1.14, but the BIOS contained new source code.
