Continue on the last blog, the Solaris PowerPC kernel boot-up on EFIKA, both as usual and unusual, on Dec 4th 2006.

As usual, which we expect due to the facts that the ODW and EFIKA use the same firmware, and it is industry standard (IEEE1275) used widely in Sun SPARC systems and Apple PowerPC systems. It is a very nice solution to provide binary compabilities for different hardware configuration. As ODW is the target machine for Solaris PowerPC development, we are not surprising at all to see the kernel bootup without problem.

As unusual, even with the same firmware in EFIKA as in ODW, there are differences in hardware, which means the firmware implementation is not the same on these two board, even they all both have the standard interfaces. Yet the differences are well addressed by the firmwares and they are transparent to the kernel. An os kernel (or a kernel loader) that is developed on top of it is BINARY portable. Please note, it is not just portable in source level or just application binary compatible.

Here is the boot log from serial port:
