Actually there is a repeated mistake in the Studio docs. Instead of Example: Any system based on the UltraSPARC chip architecture it should read Example: Any system based on the UltraSPARC II or higher chip architecture (for v8plusa and v9a) For v8plusb and v9b it would need to read Example: Any system based on the UltraSPARC III chip architecture. But this only as a side-remark. While I do not want to distract from the main topic. %mab _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
