How to change the drive boot order by code?

Hi,

I need to force a PXE boot so I need to change the boot priority. I know
boot order depends on BIOS, but how can I change it by code?

Thanks,

How to change the drive boot order by code?

I'm thinking about doing it from an application running inside the OS.
So maybe it's necesary to build a driver but, How to change the drive boot
