You would want to use an SDK that you’ve built for your BMC hardware.
bitbake -c populate_sdk obmc-phosphor-image
You’d then use that SDK the same way you used it for Hello World
and then you would scp the compiled binary to your BMC hardware.
If your bmc hardware is similar to the Romulus hardware then you
could just scp the binary you generated for Hello World over
to your hardware.

The BIOS is pretty dependent on the system. Something like this should
list all firmware images on your system, you could then introspect them
to figure out your BIOS and the appropriate D-Bus calls to read them
from an application:
busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper xyz.openbmc_project.ObjectMapper GetSubTreePaths sias "/xyz/openbmc_project/software" 0 1 xyz.openbmc_project.Software.Version

Does this mean I need to either increase the storage for the romulus, or am I simply installing it in the wrong place, and instead need to wget that into the regular VM?
