I-Coreboot (ngaphambilini ebibizwa nge-LinuxBIOS) iphrojekthi okuhloswe ngayo ukufaka esikhundleni se-firmware engakhululekile ku-BIOS yokuphathelene.
Uhlobo olusha lwe I-Coreboot 4.20 ikhishwe ezinsukwini ezimbalwa ezedlule futhi kulokhu kukhululwa benze a izinguquko eziningi ezigxile ekuthuthukiseni izici esezivele zifakiwe, kanye nokuthuthukiswa kokuvikeleka, ukuthuthukiswa kokuhambisana kanye nokusekela ukuthuthukiswa kwawo womabili amabhodi asevele asekelwa kanye namabhodi amasha.
Kulabo abangajwayelene neCoreBoot, kufanele wazi ukuthi lokhu enye indlela evulekile ehlukile kuhlelo lwendabuko lwe-Basic I / O (BIOS) ebesevele ikuma-PC we-MS-DOS 80s futhi esikhundleni sayo kwafakwa i-UEFI (Unified Extensible). ICoreBoot ibuye ibe i-analog yamahhala ye-firmware ephathelene futhi iyatholakala ukuze iqinisekiswe ngokuphelele futhi ihlolwe. I-CoreBoot isetshenziswa njenge-firmware eyisisekelo yokuqalisa kwe-hardware nokuxhumanisa i-boot.
Kubandakanya ukuqaliswa kwe-chip chip, i-PCIe, i-SATA, i-USB, i-RS232. Ngasikhathi sinye, izingxenye zebhanana ze-FSP 2.0 (Intel Firmware Support Package) kanye ne-firmware kanambambili yohlelo olungaphansi lwe-Intel ME, okudingeka ukuthi iqalise futhi ivule i-CPU ne-chipset, ihlanganiswe kwi-CoreBoot.
Izici ezintsha eziyinhloko ze-CoreBoot 4.20
Kule nguqulo entsha ye-Coreboot 4.20 okungukuthi yethula umsebenzi weziqinisekiso ezingaba ngu-1600 kusukela ekukhishweni kwangaphambilini futhi okumelela umsebenzi wokuhlanza nokuthuthukiswa okuqhubekayo okwenziwe.
Ezinguqukweni ezigqamayo kule nguqulo entsha yileso cpu/mp_init.c inika amandla ama-CPU uma esesebenzisa ikhodi, kanye ne-cpu/x86/smm yengeza ukusebenza kwe-PCI yokugcina insiza
Ngaphandle kwalokho, isikhathi sokusebenza se-SMM siqinisekisa ukuthi izinsiza ze-PCI zigcinwa kumemori ye-SMRAM ukuphepha ukuvimbela ukuhlasela okuholela ekuvuzeni kwedatha ebucayi ngokuphazamisa ukuklanywa kabusha kwe-PCI BAR.
Olunye ushintsho olugqamile kule nguqulo entsha ukuthi wengeze umshayeli ukuze afunde futhi abhale okuguquguqukayo kwe-EFI igcinwe endaweni yememori ehlukile. Lokhu kuwusizo ikakhulukazi ku-EDK2 njengomthwalo okhokhelwayo futhi kuvumela amathuluzi e-EFI akhona ukuthi aphinde asetshenziswe ukusetha/ukuthola izinketho ezisetshenziswa i-firmware.
Ngiyazi namie yengeze isilawuli se-EWL (ukungena okuyisixwayiso okuthuthukisiwe) ukuphatha amaphutha e-Intel EWL HOB, kanye nalokho wengeze ukusekelwa kwememori ye-DDR2 kukhodi ye-Intel GM45, yengeze usekelo lwe-inteltool lwe-Intel "Emmitsburg" PCH, yengeza izishayeli ze-Sound-Open-Firmware zama-Chromebook ukuze isekele umsindo kumasistimu, futhi yengeza usekelo lokungena kwe-SimNow console lwe-AMD.
Ngakolunye uhlangothi, i-Yabits payload isusiwe ngayo iphelelwa yisikhathi futhi igcinwe kungobo yomlando, njengoba ibuye igqanyiswe ukuthi izinkinga zokwakha ze-superiotool ezilungisiwe kusetshenziswa i-musl-libc, iqalise umsebenzi wokuqala ku-Xeon SPR, isuse ukwesekwa kwe-Zephyr SDK ku-coreboot-sdk njengoba inguqulo ehlanganisiwe yayindala futhi ingasetshenziswa ngempela futhi yengeza nokusekelwa kwe-inteltool kwe-Intel PCH “Emmitsburg”.
Kuthiwa kwenziwa umsebenzi wokuthuthukisa iphesenti lokushaywa kwenqolobane lapho kwakhiwa kabusha kusetshenziswa i-ccache, kanye nokuthuthukiswa nokunwetshwa kwekhodi yokukhiqiza ye-ACPI nokuthi Kulungiswe izinkinga ezithile zekhodi ye-RISC-V.
Okokugcina, kufanele futhi ukubalula ukuthi kulokhu kukhululwa okusha, kungezwe ukusekelwa kwamabhodi womama angama-25, ezingu-11 zazo ezisetshenziswa kumadivayisi we-Chrome OS noma amaseva ewebhu.

Uma ungathanda ukwazi okwengeziwe ngale nguqulo entsha ye-CoreBoot 4.18, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
Thola i-CoreBoot
Ekugcineni, kulabo abanentshisekelo yokukwazi ukuthola le nguqulo entsha yeCoreBoot bangakwenza esigabeni sabo sokulanda, engatholakala kuwebhusayithi esemthethweni yephrojekthi.
Ngokungeziwe kulokho kuyo ungathola imibhalo kanye neminye imininingwane mayelana nephrojekthi.
