I was trying to record a bios on the motherboard machinist X99 PR9 with the Chipset B85 and a Xeon E5 2650V4. I will leave the log below but i wish anyone could give me instructions about how can i help this motherboard recorder/flash to get support. root@archiso ~ # flashrom --programmer internal -c "Opaque flash chip" -w backup. bin flashrom v1.2 on Linux 6.6.3-arch1-1 (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
