Also... since VMware has been mentioned a few times, let's address the elephant in the room: the VMWare host most definitely provides the virtual machine in question with a firmware binary (a proprietary one at that) that is implemented and shipped by VMWare. So what *their* virtual firmware does is 100% independent of what SeaBIOS does. The virtual firmware is specific to the vendor of the virtualization platform.
