Where can I get reference material for the OBP in my Themis board or system?
A24. For all recent Themis products, Sun’s “OpenBoot 4.x Command Reference Manual” applies, document number 816-1177-10. For older Themis products, Sun’s “OpenBoot 3.x Command Reference Manual” applies, document number 806-1377-10. The boot-up banner will identify the core OpenBoot as 3.x or 4.x. The hardware and software manual for your specific model of Themis product will include additional commands and variables added to the standard Sun OBP to accommodate special features of the Themis hardware (e.g. – the Universe II VME interface chip).
