DragonBIOS

Phoenix DragonBIOS was a BIOS developed by Phoenix Technologies in the 90s. Not much is known about DragonBIOS, and so far only one instance of a POST screen does exist. There is a possibility that it could be a codename for PhoenixBIOS 4.01 rather than a separate BIOS, as the only known instance of the BIOS itself looks really similar to regular PhoenixBIOS.

According to a VCFED (Vintage Computer Federation) forum thread, a supposed version of DragonBIOS with the version and date "Phoenix DragonBIOS Version 4.01 - BIOS DATE: 11/05/94" has also existed, which further indicates that DragonBIOS was most likely just a codename for 4.01 rather than a seperate BIOS, either that or DragonBIOS was very quickly dropped and only release 4.01 was released.
