Tarl: is this nested boot process something that auto-boot should handle automatically based on various bootarchive properties set by the initial Fcode loader?
Sorry about the delay, I just checked my email.
I don't believe there is anything that should be automatically handled by the boot process - when you load /boot-archive, the fcode loaded should itself at the end invoke whatever execution method is required. My recollection is that boot-archive proceeds to load an ELF file and then jumps to that - I can verify that on monday.
Have we verified that OpenBios can jump to a SPARC ELF file?
