P104-100 cannot show with command `lspci`

the PC running CentOS fails to identify the P104-100 with the lspci command while it is detected on Windows OS

I have 2 PC,
PC A: p8b-x with CentOS 7, e3-1260l v1, ecc memory,
PC B no name of motherboard, gtx960, Windows 10 OS, i7-4790

  1. Insert p104 into PC A, command lspci only show one gpu who was intel
  2. Insert gtx960 into PC A, command lspci show intel and gtx960 's gpu
  3. Insert p104 into PC B, p104 also shown on Device Manager in WIN10 OS
