DESCRIPTION:Unlike the traditional BIOS that operates in 32-bit mode\, Linu
 xBios (now known as coreboot) switches to 32-bit mode almost immediately. 
 It was previously considered progressive to write firmware in 32-bit prote
 cted mode using C. However\, even though AMD released the AMD64 extension 
 in 2003\, introducing 64-bit or long mode\, coreboot remained in 32-bit mo
 de. This was adequate for coreboot's responsibility for limited hardware i
 nitialization. Nevertheless\, it now shows signs of confinement\, and adap
 ting to long mode should be considered\, especially as Intel plans to phas
 e out 32-bit mode with X86S. This presentation will outline the key achiev
 ements in enabling long mode on coreboot\, challenges encountered\, and ma
 de design decisions. It will conclude with some metric analysis and a glim
 pse into future silicon plans.
