Motherboard with superior BIOS protections [closed]

http://serverfault.com – I am planning on building a tower server for myself, and I am interested to know the various physical and firmware protections that motherboard manufacturers place on bios and firmware upgrades. The last time I built a server, the motherboard had to be jumpered for the bios to be upgraded. Are there still motherboards like this, which will only allow a bios update if the right jumper setting is set, and are there any additional protections available for the bios? Are there any motherboards where the bios chip needs to be swapped out instead of having it reflashed? (HowTos)
