Im having a hard time getting VT-D enabled on my GIGABYTE GA-Z68X-UD3H-B3. I was wondering if someone knew of a bios that could enable it.
Any help would be much appreciated.

Hi
You might well have to ask GGTS for help on this and see if they can send you a modified BIOS to suit your needs. You will also need a processor the supports it.

Please expect several days for a reply.

Hello,
I just got the answer from Gigabyte. they send me a new BIOS.
I put the links to download it in person it interrested.

yes there have been rapid. I install the BIOS, but I still can not activate the option DirectPath I / O on ESXi 5.0.
However, my CPU support (i7-2600).
If someone has an idea, I'm interested.

help please

Note that the linked BIOS is of version F5e from 07/19/2011. There is a newer 11i version on the German forums: http://forum.gigabyte.de/index.php?page=Thread&postID=58283#post58283
This newer 11i version is reported as F11i from 01/19/2012.

Hi all, ;)
Just read this topic and check link...

Try to understand why VT D technologies are not functionnal ....
Like Virtualization Technology for Directed I/O
Check why cpu or chipset not able to give VT D technologie...
After verify your CPU and Chipset.... on intel web site....
-
Gloup_Gloup, are you trying to say that VT-d is unsupported for the GA-Z68X-UD3H-B3 board (rev 1.0)? The CPU I plan to use is i7-3770.
-
if you want only VT-x technologie...
Intel® Virtualization Technology (VT-x) is right for motherboard
Intel® Virtualization Technology for Directed I/O (VT-d) are not compatible...
Intel 7-3770K
ntel® Virtualization Technology (VT-x) right
Intel® Virtualization Technology for Directed I/O (VT-d) not include , so Not compatible....
Intel 7-3770
Intel® Virtualization Technology (VT-x) Yes
Intel® Virtualization Technology for Directed I/O (VT-d) Yes
But the chipset now ...
Intel® Z68 Express Chipset
(Intel® BD82Z68 PCH)
http://ark.intel.com/products/52816/Intel-BD82Z68-PCH
http://www.intel.com/content/www/us/en/chipsets/z68-express-chipset-brief.html
Intel® Virtualization Technology for Directed I/O (VT-d) No
Intel® Trusted Execution Technology No
Intel® vPro Technology No
Intel® Active Management Technology No
So sorry, for you... The VT-D technologie are not compatible with motherboard Z68, and many other chipset....
If you want a VT-D technologie... choose a Server motherboard by Gigabyte...

I have asked a question on Superuser.com (http://superuser.com/q/609228/47108) about this, there exist Z68 mobos that support VT-d. I think that VT-d support is a software (firmware) modification.

I submitted a question and got multiple replies since I re-submitted the questions because no e-mails were shown.
Thank you for emailing GIGABYTE.
We are delighted with your interest in our products.
F12 is already supports Ivy Bridge CPU, and up BIOS F10 we have already BIOS that will supports VT-D, Please test it yourself. If The BIOS F12 do not have the VT-D, please try the attached BIOS.
Attached file:z68xud3h-f10a.zip ( 1510 KB ) (http://ggts.gigabyte.eu/FileList/1370802/z68xud3h-f10a.zip)
This F10a BIOS has listed date 09/06/2011. The version number seems not to signify anything because the download from gigabytes's main website has a different md5sum. See note on the bottom.
Does the attached F10a BIOS support all Ivy Bridge CPUs, even the E1 stepping?
Do you know people who have actually tested VT-d on any BIOS for this board?
You have stated that VT-D is supported to F10, do you mean that up to F10, VT-d is enabled by default and cannot be disabled? Or that a Beta BIOS is available which provide an option to enable VT-d in BIOS, which is disabled by default?
A follow-up reply:
Thank you for emailing GIGABYTE.

The UEFI bios will supports Ivy bridge CPU and VT-D,
You can try to flash it to U1L(UEFI BIOS)

"Bottom note":
Try it yourself, the download servers have mod_spelling enabled that help you finding all released BIOSes on their servers:

The document name you requested (/FileList/Bios/mb_bios_ga-z68x-ud3h-b3_f1u.exe) could not be found on this server. However, we found documents with names similar to the one you requested.

Hi thisisausername, ;)
But the fact are :
The VT-D .... Like Virtualization Technology for Directed I/O .... are able to make a job?
The VT-D are functionnal just with this add parameter in BIOS?
The software for Directed I/O are fine and functionnal?
Give us a new....

Hi Gloup_Gloup,
I do not understand your first point, what job are you referring to? The paychecks of GA engineers? Of course VT-d needs additional initialization, just adding the option it is not enough. If you mean "VMM" by software, that is my last worry. If the hardware supports VT-d, then eventually the software can support it as well. I do not mind a bit of hacking.
I just disassembled the U1h UEFI BIOS module 2B341C7B-0B32-4A65-9D46-E1B3ABD4C25C (Smbios131) and found out that VTd should exist in the Setup menu (this can be configured at compile time). VT-d is a feature provided by the north bridge which was previously a separate feature of the chipset, but since Sandy Bridge it got integrated on the CPU itself.
Looking further in the source code of AMI BIOS (http://www.reddit.com/r/linux/comments/1buefw/amibios_source_code_and_amis_uefi_signing_key/), it looks like VTd support is more a policy configuration rather than hardware availability (other than CPU/SB support). Presumably not to hurt sales of server boards.
Since the BIOS policy is configured to allow VT-d, there is one remaining barrier, the hardware (DRAM controller) must support it. (VT-d = Directed I/O, duh.) Support for VT-d is checked by looking at bit 7 on offset 0xe6 of the PCI device 00:00.0 (DRAM controller).
On Linux, one could run the following command:
dd if=/tmp/pcicfg-ext.bin bs=1 skip=$((0xe6)) count=1 2>/dev/null | xxd -ps
If you see "80" or something else with bit 0x80 enabled, then VT-d support is not available. Otherwise, initialization of VTd continues (init from DMAR ACPI tables). On my current SB CPU that does not support VT-d, bit 0x80 is indeed set. See page 81 of http://www.intel.com/content/www/us/en/processors/core/2nd-gen-core-desktop-vol-2-datasheet.html
Now, I will have to wait for my VT-d-capable CPU to arrive before I can test anything.
PS. this is an account I found via bugmenot, disregard all "personal details" of this profile.

Update: a working CPU that supports VT-d has finally arrived. VT-d is also working with EFI BIOS U1l. Although the Setup menu has a "Miscellaneous" section that mentions "VT-d" in its short description, it does not have an option to disable VT-d. By default, VT-d is enabled.
