Design

Coreboot usually endless a Linux kernel, but it can amount any added stand-alone ELF executable, such as Etherboot, which can cossack Linux over a network, or SeaBIOS9, which can amount Linux, Microsoft Windows 2000 and later, and *BSD (previously, Windows 2000/XP and OpenBSD abutment was provided by ADLO1011). Coreboot can additionally amount about any operating arrangement from any accurate device, such as Myrinet, Quadrics, or SCI array interconnects. Some OSes (such as Windows 2000/XP/Vista/7 and *BSD) crave bequest BIOS functions which are provided by SeaBIOS.

A different affection of coreboot is that the x86 adaptation runs in 32-bit approach afterwards active alone ten instructions12 (almost all added x86 BIOSes run alone in 16-bit mode). This is agnate to the avant-garde UEFI firmware, which is acclimated on Intel-based Macintosh computers and added newer PC hardware.

Coreboot can cossack added kernels, or canyon ascendancy to a cossack loader to cossack a kernel/image instead. It can additionally cossack a Plan 9 from Bell Labs atom directlyclarification needed. A coreboot-capable adaptation of GNU GRUB 2 exists.

By default, coreboot does not accommodate BIOS alarm services. A burden alleged SeaBIOS can be acclimated to accommodate BIOS calls and appropriately acquiesce coreboot to amount operating systems that crave those services, about best avant-garde operating systems admission accouterments in addition address and alone use BIOS calls during aboriginal initialization and as a fallback mechanism
