IGPU The graphics initialization for the igpu using "libgfxinit" in "txt mode" and SeaBIOS is compatible with both IGPU and or PCIE 16X slot used GPU from AMD/NVIDIA at the same time. It can show SeaBIOS screen on both devices. Also the G4900T CoffeeLake iGPU works fine! Using onboard GPU with ...

The built-in intel Gbe option ROM can also be included during coreboot build time, by adding the following line to "Kconfig": select MAINBOARD_USES_IFD_GBE_REGION From the make menuconfig chipset you can than enable the "Add gigabit ethernet configuration" and give location for the GBE.BIN file just ...

Could you also review your coreboot bootlogs on the Asrock H110M DVS and see if it also mentions some PCIe root Port remapping, because of ports not or wrong defined in devicetree... also the same ports? [INFO ] Found PCIe Root Port #5 at PCI: 00:1c.0. [INFO ] Found PCIe Root Port #7 at PCI: 00:1c.6 ...

Indeed good idea, before it really seems to look like a thread hijack ;-) Still I'm interested in your CoffeeLake CPU experience possibly R0 / P0 steppings, and if you modify the CPU or motherboard to fake CPU occupation. Did you know on "nuvoton pin 102" based boards it maybe possible to pin mod on ...

Coffeelake Celeron G4900T works (B0 stepping without HW pin mods nor isolation) on Asrock H110 Pro BTC+ with coreboot! I did use the original Intel ME from the original OEM 1.10 BIOS which is version 11.6.1126.0 without any ME disabler, since I read that any ME version above 11.7 will not work with ...

Progress: E3-1270-V6 Xeon on Coreboot with Asrock H110 Pro BTC+ While using the me-region from the 1.10 bios cleaned with -S option, coreboot does give Serial Debug output, recognizes CPU but no POST the system but it stays ON, previous coreboot attempts it powered down instantly after powering on ...

Some food for thought about C232/C236 with native supported XEONS like the e3-1270-v6 or perhaps coffeelake XEONS. Found a 8MB flashrom sized motherboard with same similar sized IntelME, its the Gigabye ga-x150-plus-ws with BIOS F21 and F22 supporting these Kabylake XEONS.... https://www.gigabyte ...

Also tried adding option rom via "cbfstool" instead of "ifdtool" but it probably won't load options roms did you enable that on your build? cbfstool corebootMECLEAN.rom print FMAP REGION: COREBOOT Name Offset Type Size Comp cbfs_master_header 0x0 cbfs header 32 none cpu_microcode_blob.bin 0x80 ...
