<!-- Updated Translation. Is this still needed or can it go?   OLD: When the firmware in the JavaStation (sun4m-Architecture) became version 0.8.1 Proll, a PROM replacement used in version 0.8.2, was replaced with OpenBIOS. --><!-- Double check the translation of this sentence! --><!-- Why is this sentence here in first place? -->====SPARC32====
