Hello,
We have a Phi 31s1p [1] with a Tyan 7059[2] board. There is a compatibility list from Tyan [3] which we conclude our board supports such device. In fact, the BIOS has the "above 4G decoding" option. So, we are totally sure that the board supports Phi. I have to mention that our phi is not new though!!
We have installed the Phi on one of the PCI slots.There is also another (low end) nVidia 280 on the board. When we power on the board, the LED for the nVidia blinks and the color is red. According to the manual (page 93) [2] that means it is working with lower speed. However, the LED for the Phi is solid red which is not explained in the manual (page 93) [2]. Also, there is a blue LED on the Phi and it blinks repeatedly.
Next, with the 'lspci' command on Ubuntu, there is no sign of Coprocessor or Phi.
1- What does the blue blinking LED on the Phi mean?
2- What should we do for more investigations?
Thanks.

Ubuntu is an unsupported distro. Use SLES, RHEL or CentOS.

For anyone wanting to experiment with Ubuntu - which apparently runs significantly faster than CentOS - the following page gives a view of the changes required to make it work:

Unfortunately it only covers Ubuntu 14.04 and MPSS 3.6.1

I had the problem with CentOS 7.3 with multiple used Phis , though some worked fine. I'm going to create a new topic about it.
