ESXi 5.5u1 PassThrough issues with AMD FirePro™ RG220

I'm trying to build my lab were i have an Dell C1100 server and i added in an AMD FirePro™ RG220 hoping that i'll be able to do a 1 to 1 Pass-through.

My problem is i'm able to select the AMD FirePro™ RG220 as well as the Teradaci's TERA1200 chipset, but when i restart the host and i go back to check the pass-through they are still listed as "Changes made to some of these devices below will not take effect until the host is restarted

Is there a way to solve this?amd.png

Hi

Welcome to communities.

I assume you are using inbuilt Graphics if so try to reduce the graphics memory or

use lowest power-concuption dedicated GPU

AMD FirePro™ RG220 is an add-on card PCie-x16 gen2, its an older card that "should" support pass-through, however none of the options mentioned above would work since Dell BIOS doesn't have such option in any of they Dell ProEdge C1100 series. I was shooting more for a software-side solution rather than a BIOS mods.

Any idea what could be the issue?

Maybe you can use the vmkchdev command to switch to passthrough mode.

Here is an example for disabling a nic using that command, but should be similar to every device: http://www.virtuallyghetto.com/2011/06/how-to-disable-vmnic-in-esxi.html

-bash: vmkchdev: command not found

That's a dead end - however, i've disabled the ACS in esxi and it got mapped, but the problem that i've run into was, the entire server blow its fans out of proportion and everything slowed down after doing the reboot to pass-through the card. I had to enable ACS, reboot and the server start operating normally,  although - i'm back to the same issue, when ACS is enable, i can't map it., only when disabled, but then the server overloads. Any thoughts why is this happening?

Could you try another slot to put it in?

Unfortunately Dell ProEdge C1100 has only one PCIe x16 slot.
