We have a Phi 31s1p  with a Tyan 7059 board. There is a compatibility list from Tyan  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)  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) . 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?
