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 LucasB (also known as ComputerHunter). 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.
