On server nothing is attached to other I/O boards, only I/O riser board is attached.
We were using I/O riser's 4 ethernet connections for network.
I write Centos iso file to DVD, you give. Then tried to reboot from DVD, result is as follows.
- LCD error screen is normal blue at the beginning.
- Centos first blue info screen opens normally.
- Then a black screen comes with the info: ERST: Cannot request iomem region <0x... - 0x.... > for ERST
- Then LCD error screen turns to amber with E171F PCIE Fatal err
I have also tried to use this IO riser card on a different stable server. It gives no error with this IO riser card.
