[Solved] Dell T5810(E5-1630v4, C610/X99) could NOT boot into installer

[oreym]

Ok guys, here's a clover for our PC. All the latest and freshest. Launches the High Sierra. It is used in modding based on a PowerMac G5 case with a motherboard from Dell T5810 (bios A32).
- CPU - E5 2620 v3
- GPU - PowerColor Red Devil RX570 4G
- RAM - 4x8Gb Hynix HMA41GR7MFR4N-TF
- boot - PCIex 16 addapter with NWME disk.
- WiFi/BT - Fenvi T919

Everything is working.

This bootloader is compiled by one cool russian guy.

Now, we are creating bootloaders based on Clover and OpenCore to run Catalina. If possible, I will share.

Does anyone have BIOS settings? I reset BIOS settings and now my system does not boot, Catalina 10.15.6. I use OpenCore. I had a completely working system, but now, whatever loader I use, it's error everywhere. If I use Clover, there is an error in the memory of the PCI devices.

ERROR:
[EB|`B:WFDW] Err(0xE), 0 @ LocHB 71B4903C-14EC-42C4-BDC6-CE1449930E49

Ок, I posted on github instructions for installing the Mac OS Catalina (OpenCore) on Dell T5810
