PhoenixBIOS 4.0 Release 6.x is a family of PhoenixBIOS versions developed by Phoenix Technologies from 1997 until 2002 when it was replaced by the FirstBIOS. Although it was replaced in 2002, instances of it with copyright years as late as 2006 exist. VMware's virtual machine solutions (such as Workstation Pro and Player) still use the PhoenixBIOS 4.0 Release 6.0 for BIOS-based virtual machines today.
POST screen
The POST screen of the PhoenixBIOS 4.0 Release 6.x is displayed in 640x480 resolution (with a few unused pixel lines) with an 8x19 font. It is also the first commercially sold BIOS solution with this font (excluding late instances of Intel's AMI Hi-Flex BIOS fork for their motherboards that also used this same font). AMI also started using this same font in 1999 with the AMIBIOS 07.00.xx (and later the AMIBIOS 8).
