A note to the forgetful one:
  1. I used the instructions for Sandy Bridge-E, since there are significant differences from Sandy Bridge
  2. Gathering files are also different from Sandy Bridge
  3. I completely went through all the instructions myself, collected the config and files, but I had a black screen. As it turned out, the problem was in the boot arguments ("npci = 0x3000" was missing) and the current HfsPlus.efi was not working (replacement for the previous version helped)
  4. I used not Legacy, but UEFI boot (I think I'll write about this with screenshots, so as not to forget)
  5. Now there is nothing superfluous in my EFI, the system works stably
  6. But there was one problem, I could not recover my data that I had on Catalina. Recovery system and Migration Assistant did not help
  7. OpenCore sanity checker also supports Sandy Bridge-E. Found it just now, my god :) The config fully meets the requirements. Why didn't I know about this before ..
