|Since Phoenix merged with Award many years ago, in late 90's I believe, for any mboard newer than that, the Phoenix labelling may be used on a bios chip that has an Award bios version on it, if it has an Asus supplied bios version .|
Compaq and HP brand name system bios versions are often Phoenix bios versions.
If it was supplied to a brand name system builder, it originally had a brand name system bios version, and there would probably be one or more stuck on labels on the mboard (not something printed on the surface of the mboard), one of which has bar codes and the brand name's part number for the mboard on it. Mboards used in HP and Compaq systems also often have their own unique name for the mboard printed on that label, and one label for the mboard part number, another label with the part number for the mboard with the specific cpu installed.
The label may be ontop of the parallel port.
