What is difference there is ‘Configuring devices’ line which is present with omnios, but missing with OI. It means that OI boot is just missing the device nodes to scan.

The kernel and “miniroot”  — thats what the boot_archive actually is are loaded by boot loader and boot loader is using firmware functions to do that (BIOS INT13 or UEFI Block IO). But once we start the kernel, we depend on OS drivers and features and at this stage, there is a problem with those.
