[1] OpenBIOS is a GPL2 licensed implementation of OpenFirmware.  It's more 
akin to OpenBoot on a Sparc machine whereas SeaBIOS is akin to a PC's 
traditional BIOS.

[2] OpenBIOS provides a command-line and Forth programming interface to 
setting up and booting a computer.  As-is, OpenBIOS is rather spartan. 
See http://www.tldp.org/HOWTO/SPARC-HOWTO-14.html for a rundown of what 
can be done with a Sparc machine's OpenBoot environment.

[3] If you're asking if it provides legacy BIOS compatibility, then no.
