Configuing BIOS From Linux
Configuring BIOS settings from within Linux is hard. It seems to be vendor specific.
Some Intel server boards are supported by the syscfg utility which allows you to see all sorts of goodies for IPMI and BIOS stuff.
Dell has this huge OpenManage deal. But eventually they seem to have support for Dell syscfg? (Different version)
There also seems to be some tools for "PowerEdge C" servers for "Cloud" stuff. Tools for configuring the bios from a kinda fishy website: http://poweredgec.com/
Seriously, if you have a Dell Server that starts with a C, check out the Dell setupbios command: http://poweredgec.com/files/
HP has conrep, scli, and hpasmcli. I don't know the differences between these tools yet. The possibilities are there.

- hpasmcli: http://h30499.www3.hp.com/t5/General/Possible-to-set-Boot-Controller-Order-Proliant-from-Linux/td-p/4788562#.UMJ59YMR4mk
There is /dev/nvram, but it seems to be obsolete on newer platforms with UEFI. In theory you can copy and paste /dev/nvram to other identical servers to copy bios settings.
There is also smbios-token-ctl, part of smbios-utils which should be able to, in theory, set and read bios settings that are exposed through libsmbios.
UEFI is kinda next-gen bios. There is
Somewhere in here there is at least boot order that grub-efi can control.
