[REQUEST] RAMPAGE II Extreme BIOS Unlock
#1
Hi Guys,

did i get it right, that you bunch of BIOS-Gods really made it to fix the RMRR table issue as mentioned in this thread?

http://www.bios-mods.com/forum/Thread-Ac...A-Bios-Mod

If so, would it be possible to fix it in this bios for the rampage 2 extreme?

Rampage II Extreme BIOS 1802

EDIT: Sorry for not posting a direct link, but i´ve found none.

Im dying to get this fixed, because no workaround to enable VT-d in Xen helped to get the system stable when i passthrough a usbcontroller, which are the only devices with RMRR entries. Asus does not seem to be interested or even able to get this fixed, the only statement i´ve got was "Linux is not supported". So youre my last chance before throwing away that expensive crap, and buy even more expensive, but working hardware with less features.

Muy grande thanks in advance, and please excuse my bad english. Big Grin

Hi Bunkasan,

From what I hear this has been a very frustrating issue for people. Fortunately you have a fully unlocked retail BIOS which means there's a good chance its fixable without modding. Now there are several places in the BIOS that I see Virtualization items, but under Chipset menus, and Intel VT-d configuration I see the BIOS disables this option by default. I would ensure that these are set to enabled, as well as the other various references in the Tweaker menu and the Main menu. If this doesn't work the second step would be to flash the BIOS again with the options already enabled.

Hope this helps and welcome to the forums,
TheWiz

Hi TheWiz,

I´ve already tried every option related to virtualiziation, and flashed every available BIOS provided by Asus up and down. VT-d is defintily enabled, and also working for every device without RMRR entries.

Here is a part of my bootlog, what xen says about the dmar table:

As you can see, in the second range the start-address is greater than the end-address. Huh

Only with commenting out the security shutdown in the source i´ve got VT-d to be enabled. The mentioned iommu_inclusive_mapping=1 parameter is set, but makes no difference.

In the xen-wiki they write about a modded unofficial BIOS, where this issue is fixed for the P6T Deluxe. Unfortunatly google didn´t tell me where to find it. (Not for flashing my board to death, just to provide you as much marterial as possible)

Quote: ASUS P6T Deluxe (Intel X58 chipset) requires (currently non-public) BIOS update to correct DMAR-table issue

http://wiki.xensource.com/xenwiki/VTdHowTo

So correcting this dmar entries seems to me the last chance to get rid of those nasty system freezes, when having high I/O over the usb controller passed trough (as you can see in the xen log, the two usb controllers, 00:1d.x and 001a.x, are the only devices with entries), like from webcam or external disks.

This are the Intel spec´s of the memory range found in ftp://download.intel.com/technology/comp...ect_IO.pdf :
Quote:The interrupt-remapping architecture enables system software to control and censor external
interrupt requests generated by all sources including those from interrupt controllers (I/OxAPICs),
MSI/MSI-X capable devices including endpoints, root-ports and Root-Complex integrated end-points.
Interrupts generated by the remapping hardware itself (Fault Event and Invalidation Completion
Events) are not subject to interrupt remapping.
Interrupt requests appear to the Root-Complex as upstream memory write requests to the interruptaddress-
range 0xFEEX_XXXXh. Since interrupt requests arrive at the Root-Complex as write requests,
interrupt-remapping is co-located with the DMA-remapping hardware units. The interrupt-remapping
capability is reported through the Extended Capability register.

Greetz,
Bunkasan

Do you think you could test VT-d in a windows OS and see if its working? It could very well be driver related. Also please post your CPU specs Smile

Gonna test it on Hyper-V Server, shoud reveal if Asus is right, and its really Linux related.

My system specs:

Asus Rampage 2 Extreme
Core i7 920
12 GB Corsair XMS3
Nvidia 7600GT
ATI HD 5870

I will post the results as soon as the Hyper-V is up and runnig.

Bug 
I have an issue with my board that I cant figure out (no, its on the CMOS batter or bad Bios chip).

My board always detects "New CPU" on boot forcing me to keep default settings (no overclock possible). Can this feture be bypassed safely? Willing to pay first modder that can provide a bios that fixes this issue.

Bump for some help.

Can anyone mod a Rampage II Extreme Bios to bypass "New CPU detected" feature?
