Bottomley: Owning your Windows 8 UEFI Platform

Well there was SMM for some time with its crappy interface (write ebx to port 0x20 and see all the registers changed) which I cannot call real mode even if it is .code16gcc. That thing handle hard disk emulation of USB drive, keyboard and mouse - which is not present in the standard BIOS in between segments 0xE000 and 0xFFFF.
I hope SMM has gone from EFI.
BIOS is not perfect neither with no standard support of network card (put a packet on the wire / read last packet from the wire) and no support for multiple screen/keyboard.
