Thanks for your answer!
I can enter into cmos-setup when running VMware,so I want to have a try
with qemu/kvm.
I have read Seabios's document,found that there were items that could
be configured with "qemu-system* --fw_cfg",and only some of items was
related to cmos setup.
Yes, some of the stuff you usually find in the cmos setup on physical
hardware (boot device order for example) is configured with qemu command
line switches instead.
fw_cfg (shortcut for firmware config) is the name interface used to pass
this information from qemu to the firmware (be it seabios, ovmf or
something else).
