Everything work fine. Except the video for very high definition (4K).

Saw this post about Dell M4800 working well below.  I bought one and attempted to install Q ubes 4.0.

I am getting IOMMU/VT-d/ADM-Vi, Interrupt Remapping warning.

It will partially install with the warning(s) above.  Depending on the BIOS setting I get

IOMMU/VT-d/ADM-Vi 

HAP/SLAT/ET/RVI warning.  somtimes I get both errors

Can you suggest any BIOS settings I can change ?

I have set it enable EUFI.

I have set "Enable Legacy Option ROMs off/on (both)

I have set "Enable Intel Virtualization Technology enable/disable (both)

TPM enabled - does not work.

I can find no combinations that works.

Please help.

Have you tried with legacy boot, UEFI did not work for me either.

[Scott Mason]

Yes.

Both UEFI and Legacy.

I set BIOS to Legacy and try to re-install.  I get:

IOMMU/VT-d/ADM-Vi, Interrupt Remapping  

 i7-4710MQ CPU  

This is a i7 24Mb laptop I bought just for Quebes.  I am going to have to sell this laptop or give up on Quebes.  :/

I don't know what else I can do.  ???

[Scott Mason]

Solved:

I have found this and I think it would serve the entire Qubes community when checking hardware requirements:

How do I know if my CPU supports VT x or AMD-V?

Method 3: Visit Intel’s product specification site. Visit Intel’s product specification site (https://ark.intel.com/) and follow these steps:

1. Once on the site, enter the processor information you noted above in the search box located on the right-hand side of the page.

2. Under “Advanced Technologies” on the product page for your processor, you will see whether Intel® Virtualization Technology (VT-x) is supported or not.   It will show Yes or No

If you do this before you purchase or attempt to install Qubes you will have some assurance that Qubes will work.

My configuration for the Processor Intel(R) Core(TM) i7-4710MQ CPU @ 2.50GHz, 2501 Mhz, 4 Core(s), 8 Logical Processor(s) says:

•   Intel® Virtualization Technology (VT-x) ‡ Yes

• Intel® Virtualization Technology for Directed I/O (VT-d) ‡ No

I don't know of other options I can try.  I am sure an expert could tweak this.  I just don't have the time.

This resource has been mentioned regularly on the mailing list, and is
on the hardware requirements page in the docs.
Unfortunately it only provides *part* of the assurance that is needed -
we do see people who have CPU capable of VT-x, but are unable to get
it working.
The thing is that you need **both** a board **and** a CPU which are VT-x
or AMD-V capable.
The usual advice is that you ask the manufacturer before purchase -
that way you have iron clad guarantee of getting money back if support
is not available.
Or select model from HCL.
