PhoenixBIOS: Difference between revisions

Revision as of 17:20, 28 January 2024

PhoenixBIOS is a personal computer BIOS developed by Phoenix Technologies since 1983. Nowadays, it has been mostly replaced by Phoenix's UEFI solution SecureCore.

PhoenixBIOS is the first fully IBM PC compatible personal computer BIOS that was mass licensed to other system manufacturers. Before its introduction, manufacturers (often illegally) reverse engineered the IBM BIOS for PC compatibility on their computers. It is therefore also the starter of the competition between Phoenix and other commercial BIOS vendors that came up with their own solutions later on (such as American Megatrends with their AMIBIOS and Award Software with their AwardBIOS).
