Can't update Server GEN9 with internal dvd-rom

Hi,

when i'm trying to update SPP or intelligent provisiong on a Gen9 server (DL and ML) using the internal dvd-rom with a bootable CD, after the loading system returns a black screen with "error kernel".

With the same CD but an external dvd-rom there isn't this problem.

can someone help me?

Thanks,

Gabriele CIaldini.
