  Some days ago, I ask Linus to borrow his Larrabee GPU. Now I got some news.

  I test 4 hours, and made Larrabee can work.

  Although it just show 'Microsoft display adapter' in the Windows(Because I also doesn't have drive)

.  But, other player's Larrabee just shows 'Unkonw device' in the Windows System. But this Larrabee can show 'Microsoft display adapter', it can be recognized as a graphics card in the Windows System!! This Larrabee may be the only other player in the world that can be recognized as a graphics card.IMG_8904.thumb.jpeg.fdeecf7f3850c8458a2bf2b0349ceb77.jpeg

 (By the way, it is work ,but its buzzer will always sound, like '—.—' one long one short one long.

[My test motherboard:Gigabyte-Z78X-UD5H(But you also need put HDMI or DP in motherboard, Larrabee can't used alone like P106 GPU)]AFBD5882D1BB47ADEB367F871DEEE0F3.png.96f738365034be7b765f9701ef09c5ce.png155AA018514961C787151C5C6CC9AA1D.thumb.png.5847604534be3b0b57b257c2dd1932b9.png

I am very much intrigued as to how you got the card to work! I have a Larrabee card myself and I have been trying for months to get it working even as a coprocessor. Did you modifiy the drivers in any way?

You could try adding the PCI-E ID to the intel graphics driver to see if trying to use the Intel graphics driver makes it work, but the chances of it working seem very low given that it is expected to be a completely different architecture from Intel’s other GPUs.

I actually tried that but I had no luck whatsoever. Even tried a driver from around the time but the driver just threw a fit and didn't even attempt to detect the card.

No, just installed MPSS.

Which version of MPSS did you use? My card didn't work with MPSS at all. The card uOS got stuck in a boot loop when I tried to start the card with MPSS commands as it was trying to boot from a Knights Corner image rather than Knights Ferry.

@YuuKi-AnS

 

Does your Larrabee boot as 2D without any other card in the system?

Oh okay I misunderstood. I guess that one may be actually working. Doubt 3D performance is working as expected tho...

Any plans to re-visit this? I noticed a few comments on the YouTube video mention that they had drivers, but they might have been the MPSS or just BS.

My card doesn't show up as a display adapter for me. Just shows up in Device Manager as "coprocessor", not under display adapters

GPU Z and Speccy both show nothing for me

In cmd I can use micinfo and it just says "Knights Ferry - unknown error"

 

Which exact driver did you use for the card and how exactly did you install it?

Hey, guy. Is there any BIOS data in the BIOS Flash on your Larrabee? Can you give me a copy of the BIOS Data?

I've got access to three Knights Ferry cards. One of them I'm pretty sure has a corrupted BIOS or something as it doesn't get as far as the other cards in terms of trying to boot the card uOS

Update

I finally got round to installing MPSS 3.8.6 and the card seemed to be detected properly and everything seemed to set up fine, but issuing the command micctrl --start still doesn't cause the card to boot. I get the error mic0: boot failed (mode: Linux image: \bzImage-knightscorner.bin)
