Coreboot on firmwareprojekti, joka kehittää vapaan ohjelmiston vaihtoehtoa BIOSille ja UEFIlle. Koska ohjelma on suurelta osin laitekohtainen (Coreboot ladataan ennen käyttöjärjestelmän ydintä) on siihen ohjelmoitava tuki erikseen eri laitteille.

Coreboot on aiemmin tunnettu nimellä LinuxBIOS.[1] Projekti on laajentunut alkuperäisestä Linuxin käynnistävästä firmwaresta tukemaan myös esimerkiksi Plan 9 -käyttöjärjestelmää.[1] Coreboot on saatavilla eri arkkitehtuureille kuten RISC-V-suorittimille.[2]

Corebootin eduiksi lasketaan tehokkuus (karsimalla ylimääräiset ohjelmistot tietokone käynnistyy nopeammin) sekä turvallisuus (vähentämällä mahdollisia hyökkäyspintoja).[3] Koska Coreboot on avointa lähdekoodia se voidaan auditoida ja sitä voidaan muokata.[4]

Muun muassa System76 on julkaissut kannettavia tietokoneita, joissa on Coreboot.[3]

Historia

Coreboot-projekti sai alkunsa Yhdysvalloissa Los Alamos National Laboratoryssä vuonna 1999 kahden opiskelijan projektina. Sittemmin projektin parissa on työskennellyt suuri joukko ihmisiä.

Rahoitus

Muun muassa Google, AMD, Acer ja Saksan valtio ovat tukeneet projektia.
