Hello guys, recently I bought used HP Elitedesk 800 G6 Tower for as a Proxmox/VM homelab server. I opted for this solution because it has VPro and not knowing all things around I thought it was a good idea. Then I realized things liek HP has RSA signed bioses. It’s problematic to impossible to mod them etc. Because of virtualization / GVT-g I really need to increase Aperture size. This option isn’t in the Bios, so tried to change UEFI variable. I used UEFITool and tried look into UEFI file. I see Aperture size mentioned in HPSetup module but if I use IFR extractor, I don’t see Aperture Size in the extracted files. I only found varstore UmaVideoMemory which I tried to modify through UEFI shell, but I got access denied. I even tried to downgrade to the oldest Bios supported for this computer ( version 2.0.1 - initial production release from 2020 ) but no change, still got access denied. I am not sure if it’s even possible to solve this problem. Maybe someone more experienced could help with this?
If you need any additional information, let me please know.
Thank you so much!
Lukas
