Open Source BIOS is not only choice.

> For booting Windows after you installed linuxbios.

You still aren't makeing sense to me.  Booting a COTS bios after you
boot linuxbios to boot windows is a regression not an advancement. 
You aren't getting any extra features.  You are just adding
complexity.  If you are going to boot a COTS bios then just boot the
COTS bios you don't need linuxbios.
