[ Hint ] Just a tip to install Proxmox VE in Dell R620

Hello @Gilberto Ferreira,
I stumbled on your post because I recently got an R620 with H310 and am facing the issue of "No Hardisk Found" with the DMAR DRHD error. There are multiple posts I have found about R620s and H310 having issues but none I could find with actual solutions that I can follow.
You stated "After disable the RAID controller everything is ok!" I just want to ask what is the step by step process you followed to disable the RAID?
I have tried to go System Setup > System BIOS > SATA Settings > and played with the "Embedded SATA" setting (ATA Mode, AHCI Mode, RAID Mode, and Off) and none of those allow for the installation to recognize a harddisk.
I also have tried to go into Integrated Devices (under System Setup > System BIOS) and set "Integrated RAID Controller" to Disabled but that completely disables the Controller.
I have seen/read where people overwrite the firmware to allow IT Mode, but unless it is absolutely necessary for my setup to work, I rather try your method first.
Can you share the steps please?

You can follow the instruction in this web site:

https://fohdeesha.com/docs/index.html

Click in PERC Cross Flash and find you RAID controller.

To be honesty, I don't recall what I do at that time.
But I think the Fohdeesha guide will help you.

Keep us posted about your progress.
