I-Coreboot (eyayibizwa ngaphambili ngokuba yi-LinuxBIOS) yiprojekthi ejolise ekubuyiseleni i-firmware engahlawulelwayo kwi-BIOS yobunikazi.
Inguqulelo entsha ye ICoreboot 4.20 yakhululwa kwiintsuku ezimbalwa ezidlulileyo kwaye kolu kukhululwa benze a utshintsho oluninzi ezijolise ekuphuculeni iimpawu esele ziphunyeziwe, kunye nokuphuculwa kokhuseleko, ukuphuculwa kokuhambelana kunye nokuxhasa uphuculo lweebhodi esele zixhasiwe kunye neebhodi ezintsha.
Kulabo abangaqhelekanga ngeCoreBoot, kuya kufuneka uyazi ukuba yile umthombo ovulekileyo ongasetyenziswa kwinkqubo yesiqhelo ye-I / O yesiqhelo (BIOS) esele ikho kwii-PC ze-MS-DOS 80s kwaye iyitshintsha nge-UEFI (Unified Extensible). ICoreBoot ikwayi-analog yasimahla yokuthengisa i-firmware kwaye iyafumaneka ukuze kuqinisekiswe ngokupheleleyo kwaye kuphicothwe. I-CoreBoot isetyenziswa njenge-firmware esisiseko sokuqaliswa kwezixhobo kunye nolungelelwaniso lokuqalisa.
Kubandakanywa ukuqaliswa kwe-chip chip, i-PCIe, i-SATA, i-USB, i-RS232. Kwangelo xesha, i-FSP 2.0 (Intel Firmware Support Package) ye-binary element kunye ne-firmware ye-Intel ME esezantsi kwenkqubo, ekufuneka iqalise kwaye isungule i-CPU kunye ne-chipset, zidityanisiwe kwi-CoreBoot.
Iimpawu ezintsha eziphambili zeCoreBoot 4.20
Kule nguqulo entsha yeCoreboot 4.20 leyo inika umsebenzi omalunga ne-1600 lokuqinisekisa ukususela ekukhutshweni kwangaphambili kwaye omele umsebenzi wokucoca kunye nokuphuculwa okuqhubekayo okuphunyeziweyo.
Kwiinguqu ezigqamayo kolu guqulelo lutsha kukuba cpu/mp_init.c yenza ii-CPU zisebenze nje ukuba ziqhube ikhowudi, kunye ne-cpu/x86/smm yongeza i-PCI yokugcina izixhobo zokusebenza
Ngaphandle koko, ixesha lokusebenza le-SMM liqinisekisa ukuba izixhobo zePCI zigcinwe kwimemori ye-SMRAM ukhuseleko lokuthintela uhlaselo olukhokelela ekuvuzeni kwedatha enovakalelo ngokuphazamisana nePCI BAR yokwenziwa kwakhona.
Olunye utshintsho olwahlukileyo kule nguqulo intsha kukuba wongeze umqhubi ukuba afunde kwaye abhale ii-variables ze-EFI igcinwe kwindawo yenkumbulo eyahlukileyo. Oku kuluncedo ngakumbi kwi-EDK2 njengomthwalo wokuhlawula kwaye ivumela izixhobo ze-EFI ezikhoyo ukuba zisetyenziswe kwakhona ukuseta / ukufumana iinketho ezisetyenziswa yi-firmware.
Ndiyazi name yongeza umlawuli we-EWL (ukuphuculwa kwesilumkiso sokungena) ukuphatha iimpazamo ze-Intel EWL HOB, kunye nokuba yintoni yongeze inkxaso yememori ye-DDR2 kwikhowudi ye-Intel GM45, yongeze inkxaso ye-inteltool ye-Intel "Emmitsburg" PCH, yongeza abaqhubi be-Sound-Open-Firmware kwii-Chromebooks ukuxhasa isandi kwiinkqubo, kwaye yongeza inkxaso yokungena kwe-SimNow console ye-AMD.
Kwelinye icala, Yabits payload isusiwe ngayo iphelelwa lixesha kwaye igcinwe, kwaye igxininiswe oko imiba elungisiweyo yokwakha i-superiotool usebenzisa i-musl-libc, iphunyezwe umsebenzi wokuqala kwi-Xeon SPR, yasusa inkxaso ye-Zephyr SDK kwi-coreboot-sdk njengoko inguqulelo epakishweyo yayindala kakhulu kwaye ingasetyenziswanga ngokwenene kwaye yongeze inkxaso ye-inteltool ye-Intel PCH “Emmitsburg”.
Kukhankanyiwe ukuba umsebenzi wenziwa ukuphucula ipesenti ye-cache hits xa kusakhiwa kwakhona usebenzisa i-ccache, kunye nokuphuculwa kunye nokwandiswa kwekhowudi yokuvelisa i-ACPI kunye nokuba Kulungiswe imiba ethile ye-RISC-V ikhowudi.
Okokugqibela, kufanelekile ukukhankanya ukuba kolu kukhutshwa lutsha, yongeze inkxaso yeebhodi zee-25, i-11 yazo isetyenziswa kwizixhobo ze-Chrome OS okanye iiseva zewebhu.

Ukuba unomdla wokwazi ngakumbi ngale nguqulo entsha yeCoreBoot 4.18, unokujonga iinkcukacha Kule khonkco ilandelayo.
Fumana iCoreBoot
Okokugqibela, kwabo banomdla wokufumana le nguqulo intsha yeCoreBoot banokuyenza kwicandelo labo lokukhuphela, enokufumaneka kwiwebhusayithi esemthethweni yeprojekthi.
